1.1 Display Configuration and Messages
The display on MD200 open chassis drives consists of a 3-digit, 7-segment LED display with 2 status LEDs at the top of the display and a Decimal Point LED at the bottom between the 2nd and 3rd digits. Refer to the diagram below for details.
1.1.1 Seven-Segment and Status LED Display
This manual will use the following terminology when referring to the Status LEDs: Left Status LED – Top Left Corner, Right Status LED – Top between 2nd and 3rd digits.
OFF ON BLINK
1.1.2 Display During Power-Up
Display flashes the parameter set number between 300 and 399 for about 2 seconds.
1.1.3 Display With No Run Command
The three center segments are illuminated continuously.
1.1.4 Displaying Target and Actual Frequencies
If the commanded frequency is changed while the drive is stopped the set frequency will display and the Left Status LED will illuminate. After about five seconds, the display will begin alternating between the set frequency and the stop indication shown in 1.1.3 above. Press the Mode button to stop the alternation, if desired.
Set frequency (10.2 Hz shown). Left Status LED illuminated.
When the drive is started, the display will show actual frequency as the drive ramps up to the target frequency. The Left Status LED will flash to indicate that the drive is accelerating or decelerating. If the target
frequency is changed during drive operation, the display will indicate the target frequency until the actual and target frequencies agree. At this time, the Left Status LED will illuminate steady for about five seconds and then extinguish. This indicates that the target frequency has been
1.1.5 Changing the Frequency Command Source
The source of the frequency command can be changed while the drive is running. For example, a digital input may be programmed to change from the 0-10 VDC input to 4-20 mA input. If this is done, the display will momentarily show a message to indicate the new speed source. Refer to Table 1.1 for a description of these messages. If the drive is being
controlled by any other source besides the ∆ ∇ buttons, a press of the ∆ or ∇ buttons will cause the display to momentarily display the frequency source. Example 1: Assume the drive is running and the present frequency
reference is the keypad and TB13A is programmed to select a 4-20 mA signal as the speed source. When TB13A is connected to TB2, the display will flash “EI” to indicate that the frequency reference was changed to the 4-20 mA signal. If TB13A is opened, the display will flash “CP” to indicate the reference was changed back to the keypad.
Example 2: Assume that the frequency reference is a 0-10 VDC signal. If the ∆ or ∇ button is pressed, the display will flash “EU” to indicate that the reference is the 0-10 VDC input and that the ∆ or ∇ button cannot be used to change the frequency.

2.0 Safety
Safety is an important concern when working with any electrical equipment. AC drives operate at dangerous voltage levels and
dangerous voltages can be present for several minutes after power is removed. Only persons experienced with the installation, operation and maintenance of AC drives should be allowed access to the drive enclosure. Failure to follow proper electrical safety procedures could lead to serious injury or loss of life.
2.1 Danger
This manual will use the following symbol when, due to the nature of the procedure, serious injury or possible loss of life is an issue.
The symbol will be accompanied by a boxed description in bold text describing the potential safety issue and steps to take to avoid injury. An example is shown below.

POTENTIALLY LETHAL VOLTAGES EXIST IN THIS DRIVE AND MAY REMAIN AT A DANGEROUS LEVEL FOR
SEVERAL MINUTES AFTER POWER IS REMOVED. BEFORE ATTEMPTING TO SERVICE THIS CONTROLLER, WAIT 3 MINUTES AND MEASURE THE DC BUS VOLTAGE TO INSURE THAT IT IS ZERO.
The DC bus voltage can be measured by placing a DC voltmeter suitable for 500 VDC (230V drives) or 1000 VDC (460V or 590V drives) across the B+ and B- terminals. Only an experienced electrician should attempt this measurement.
!
2.2 Caution
In addition to the Danger symbol and typical statement shown above, some actions have a smaller potential for injury but failure to follow proper
procedures could cause damage to the drive or to the driven equipment. This manual will use the following symbol when the operation requires care in performing the procedure but conditions are not normally life threatening.
The symbol will be accompanied by a description in bold text describing the potential safety issue. An example is shown below. Notice that Caution alerts are not boxed.
!
CAUTION
CONSULT THE MANUFACTURER OF THE MOTOR AND THE DRIVEN MACHINE BEFORE OPERATING THE MOTOR ABOVE RATED SPEED. FAILURE TO DO SO MAY RESULT IN DAMAGE TO EQUIPMENT AND/OR PERSONAL INJURY.
2.3 General Safety Precautions
2.3.1 Always
• Read and understand the contents of this manual before attempting to install or service the AC drive.
• Allow only qualified persons experienced with the installation, set-up and maintenance of power electronic devices to work on this
equipment.
• Disconnect power before attempting to work on the drive or connected motor.
• Follow plant and electrical code lockout procedures to insure that power is not accidentally applied while working on the drive, motor or driven machinery.
!
• Measure DC bus voltage with a meter capable of handling DC voltage up to 1000 V to insure that the DC bus capacitors have fully
discharged before touching any components or terminals in the drive enclosure or before opening the motor conduit box.
• Insure that proper grounding procedures have been followed during installation of the AC drive and motor.
• Follow proper procedures for handling static electricity sensitive electronic equipment.
• Insure that the AC line voltage at the drive installation agrees with the drive rated voltage, as imprinted on the ratings label on the side of the drive or as listed in the Specifications, Section 8 in this manual.
2.3.2 Avoid
• Working on the drive when power is applied unless absolutely necessary for troubleshooting purposes and then only by a qualified electrician.
• Touching the drive heatsink because of the possibility of burns due to elevated temperature.
2.3.3 Never
• Remove or install the drive cover while voltage is applied. • Never stand directly in front of the drive when applying power.
• Never connect or disconnect any wiring, either power or control, while power is applied to the drive.
• Never touch any component on an electronic circuit board with power applied. Some components are at DC bus potential.
• Never short the DC Bus (B+) and (B-) terminals to discharge the DC bus capacitors.
• Never run conductors from multiple drives and motors in the same conduit or raceway.
!
DANGER
HAZARD OF ELECTRICAL SHOCK OR BURN!
NEVER ROUTE CONDUCTORS BETWEEN MULTIPLE MOTOR AND DRIVE COMBINATIONS IN THE SAME
CONDUIT OR RACEWAY. OPERATION OF ONE DRIVE MAY RESULT IN VOLTAGE BEING INDUCED INTO A SET OF MOTOR LEADS EVEN THOUGH THE DRIVE SUPPLYING THAT MOTOR IS OFF AND DISCONNECTED FROM ITS POWER SOURCE.
!
CAUTION
ROUTING MULTI-MOTOR, MULTI-DRIVE CONDUCTORS IN THE SAME CONDUIT OR RACEWAY CAN RESULT IN DAMAGING VOLTAGE TRANSIENTS THAT CAN CAUSE PREMATURE MOTOR AND/OR DRIVE FAILURE.
3.0 Inspection and Storage
3.1 Inspection
Always inspect MD200 AC drives upon receipt to insure that no shipping damage has occurred. If damage is suspected, contact the freight carrier immediately to file a damage claim. Also, contact your local Sumitomo Machinery Corp. of America (SMA) Representative or Distributor to receive a Return Material Authorization and return the drive for inspection and, if
necessary, replacement or repair. Attempting to install or operate a drive that has been damaged may create a safety hazard.
The following signs may indicate possible shipping damage that should be investigated further:
• Visible damage to the drive shipping container including cuts, tears or punctures.
• Signs that the container may have been dropped such as deformed corners.
• Signs that heavy items may have been stacked on top of the drive container such as caved-in top, bottom or side.
• Opened containers.
• Loose parts inside the shipping container. • Evidence of water damage.
3.2 Storage
If the AC drive is not to be installed immediately, it should be returned to its original shipping container and stored in a location that meets the following conditions.
• Temperature maintained within -20°C to +70°C (-4°F to 158°F). • Not prone to large temperature swings.
• Humidity within a range which will not result in condensation. • Away from dripping or splashing liquids.
• Atmosphere is free from corrosive gasses and/or conductive dust. • Free from excessive vibration.
4.0 Installation
4.1 General Precautions
MD200 SERIES DRIVES ARE SUITABLE FOR INSTALLATION IN A UL POLLUTION DEGREE 2 ENVIRONMENT ONLY. THEY ARE UL OPEN CHASSIS (IEC DESIGNATION IP20) DEVICES AND MUST BE INSTALLED WITHIN A SUITABLE ENCLOSURE WHICH AFFORDS MECHANICAL PROTECTION FOR THE DRIVE AND PREVENTS ACCIDENTAL
CONTACT OF THE USER WITH POTENTIALLY HARMFUL VOLTAGES.
4.2 CE Installation Requirements
4.2.1 EMC Directive Considerations
MD200 drives are CE Listed and can be used in European Community countries. A Declaration of Conformity appears in Section 10, CE Declarations. MD200 drives meet the requirements of the Low Voltage Directive without modification. Compliance with the EMC (Electromagnetic Compatibility) Directive requires additional equipment and special installation considerations.
A motor drive does not generally function independently. It is a component designed to be integrated into a machine control system, and is generally intended to be installed within another enclosure with other control
equipment and devices. It is therefore assumed that the drive is installed in such a manner, and to assure compliance with the EMC Directive, the drive is tested in this configuration. Compliance with the EMC (Electromagnetic Compatibility) Directive requires additional equipment and special installation considerations. The following guidelines must be implemented in addition to standard installation guidelines as described in this manual. Refer to Figure 4.2.1 on the following page for additional information.
1. The drive must be installed in a metallic enclosure designed to contain radio frequency energy. Basic requirements include RFI gasketing around all door or removable cover joints and continuous welded seams for any enclosure joints.
2. AC line input wiring must be routed in rigid metal conduit or metal jacketed flexible conduit. The conduit must be securely attached to the enclosure with paint or other insulating material removed at the point of attachment to insure positive electrical contact.
3. A separate ground conductor must be routed inside the conduit
carrying the AC line conductors. The ground conductor must be solidly connected to the enclosure ground stud.
4. The drive and motor must be solidly grounded to the same point. 5. Install a 1 % minimum impedance line reactor, as required, between
the drive and the power source.
6. An approved Radio Frequency Interference (RFI) filter must be installed between the drive and the power source.
7. If required, a load reactor with a minimum of 1% impedance may be installed between the drive and the motor.
8. Shielded power cables must be used to connect the motor to the drive. The shielded cable must include a separate ground conductor tied to the drive heatsink on one end and the motor ground terminal on the other end. The braided shield or drain wire must be grounded to the drive heatsink.
9. Shielded cable must be used for all control wiring entering or leaving the enclosure that contains the AC drive. The shield must be solidly attached to the drive ground terminal.
10. A ferrite bead must be installed on control wire or cable entering or leaving the enclosure that contains the AC drive.

4.2.2 Low Voltage Directive Considerations
A power system is unique in its safety concerns and the methods used to ensure the safety of people, animals, plant and equipment. The applicable standard for this product family is EN50178: 1998 Electronic Equipment for use in Power Installations. This standard details the design requirements and verification testing required for power electronic systems, including motor drive products, and we have self-certified compliance to the Low Voltage Directive according to this standard.
1. 200-230 V Applications – MD200 drives are dual rated for 200 or 230V operation and carry a higher full load ampere rating when operated at 200V. The drive ratings tables and nameplate list 2 output current ratings. The higher current rating corresponds to the lower voltage rating and the lower current rating corresponds to the higher voltage rating. The result is that the VA rating of the drive stays essentially constant. For example, a 2 HP, 200/230 V rated drive lists output current of 7.8/6.8A. The rated current at 200 V is 7.8A and the rated current at 230V is 6.8A. In order to maintain conformity with CE, the drive must be applied to a motor with both voltage and current rating within the rating of the drive. Using our 2 HP example, if a motor with a 230V rating is applied to the drive, the rated amperes must not exceed the 230V rating of 6.8A. The additional 1.0A (7.8 – 6.8) is not available at the higher voltage.
2. 400-460V Drives – The same conditions apply as described in item 1 above.
3. The drive must be properly grounded by connecting the ground terminal on the drive to a solid earth ground using a conductor with a current rating equal to or greater than the current rating of the AC line feeder
conductors. Wire each drive of a multi-drive installation to a common ground point. Do Not daisy chain the ground conductor between drives. 1. Do not use an Earth Leakage (Ground Fault) circuit breaker ahead of
the drive as a means for personnel protection.
2. Current limiting fuses must be used in the AC line feeding the drive even if a suitably sized circuit breaker is used. Refer to Section 4.4.1, Paragraph 4 on Page 13 for fuse recommendations.
4.3 Mounting Location
If an open chassis style MD200 AC drive is being installed, it must be panel mounted in a suitable enclosure. Ambient temperature inside the enclosure must be within the drive specification. Refer to Section 8, Specifications for information on MD200 drive losses. NEMA enclosed drives can be mounted in any location within the limits of the NEMA rating of the enclosure. For example, a NEMA 1 enclosed drive must not be mounted in a location where there is a possibility of water entering the enclosure.
!
CAUTION
AVOID TOUCHING THE DRIVE HEATSINK DURING AND FOR SEVERAL MINUTES AFTER OPERATION. NORMAL OPERATING TEMPERATURES MAY CAUSE BURNS. INSURE THAT THE MOUNTING LOCATION IS SUITABLE FOR THE EXPECTED TEMPERATURES.
If the drive is installed in another enclosure, the enclosure must be sized according to the heat dissipation of all installed components and additional ventilation supplied, if needed. The enclosure must include a door, cover, etc. to prevent accidental contact with terminals or other drive parts that are at hazardous voltage levels.
In general, the mounting location should meet the following criteria. • Temperature maintained within the drive specified operating range as
listed in the Specifications, Section 8 of this manual.
• Not prone to large temperature swings which could cause condensation. • Humidity maintained within a range that will not result in condensation. • Away from dripping or splashing liquids unless the enclosure carries a
NEMA 4 rating.
• Atmosphere is free from corrosive gasses and/or conductive dust. • Not prone to excessive vibration.
• Heat sink fins must be oriented vertically. • Airflow must not be obstructed.
• Avoid mounting the drive above a heat source (including another drive). • Maintain a minimum of 1 in. (25 mm) horizontal and 2 in. (51 mm) vertical
clearance between a drive and adjacent components including the enclosure wall.
• Install a space heater if the ambient temperature inside the enclosure is likely to fall below 0°C (32°F). A space heater should also be used to minimize condensation if high humidity combined with large temperature swings is anticipated.
4.4 Electrical Installation
!
DANGER
HAZARD OF ELECTRICAL SHOCK OR BURN!
FAILURE TO FOLLOW SAFE ELECTRICAL PRACTICES CAN RESULT IN SERIOUS INJURY OR DEATH. BEFORE
COMMENCING INSTALLATION INSURE THAT ALL SOURCES OF POWER ARE TURNED OFF AND LOCKED OUT.
MD200 AC drives must be installed in accordance with the requirements of any national and / or local electrical codes in effect at the point of installation. An experienced electrician, familiar with the handling of solid state power conversion equipment, must perform the installation. In addition to normal electrical safety procedures, the following items must be
considered in planning the installation. 4.4.1 Power Wiring
1. Remove all power from sources that feed the AC drive and any associated equipment. Install safety lockout devices in accordance with standard electrical safety practices.
2. Insure that feeder conductors and motor conductors are sized in
accordance with applicable electrical codes. Refer to the drive nameplate or Specifications Section of this manual. If long cable runs between the AC drive and power source are anticipated, insure that the conductors are sized to compensate for voltage drop due to the cable impedance. Failure to do so could result in reduced performance from the AC drive and
connected motor.
3. The available short-circuit current at the drive input terminals must not exceed 5,000 RMS Symmetrical Amperes. Use of a line reactor or
isolation transformer may be used if necessary to meet this requirement.
4. The drive should be connected directly to the power system through an appropriately sized current limiting fuses and a disconnecting means. Fuses should be Bussman Type KTKR rated for 2 Times the drive input current, but not less than 10 Amps. The use of a contactor between the drive and power supply should be avoided. If it is absolutely necessary to install a contactor, take care to insure that the contactor is not cycled rapidly to remove and reapply power to the drive. Removing and
reapplying power more often than 6 times per hour may damage the DC bus capacitor precharge circuit and will void the drive warranty.
5. Feeder cables to the AC drive must be run in metallic conduit or covered
metal wire-way to minimize radiated electrical interference that could affect nearby electronic devices or cause interference in communication devices. Conduit or wire-way must be properly grounded. In some installations with sensitive electronic equipment, in may be necessary to install a properly sized Radio Frequency Interference (RFI) filter between the AC drive and the power system. Consult the factory for filter
recommendations.
6. Do not run motor leads in the same conduit as input power leads. Switching noise on the motor leads will be coupled into the AC line.
7. Conductors from the drive output to the motor must be run in metallic conduit or covered metal wire-way to minimize radiated electrical interference which could affect nearby electronic devices or cause interference in communication devices. Conduit or wire-way must be properly grounded. In some installations with sensitive electronic equipment, it may be necessary to use shielded cable for the motor conductors. An installation that must meet CE listing requirements will require shielded cables between the drive and motor.
8. MD200 AC drives use Insulated Gate Bipolar Transistors (IGBTs) in the inverter section. The extremely fast switching speed of IGBTs can result in potentially damaging voltage spikes being present on the motor leads. This potential increases dramatically with increasing motor cable length. Refer to Section 4.4.2 for additional details.
9. Do not run power cables from one drive-motor combination in the same conduit or raceway as power cables from another drive-motor
combination. This can cause coupling of voltage present in one set of motor leads into another set of motor leads. Potentially damaging voltage transients can occur resulting in damage to the connected motors and a safety hazard can result because even though one of the drives may not be operating, the motor leads can have potentially lethal voltage levels present.
!
DANGER
HAZARD OF ELECTRICAL SHOCK OR BURN!
DO NOT ROUTE MOTOR LEADS FROM MORE THAN ONE DRIVE-MOTOR COMBINATION IN THE SAME CONDUIT OR RACEWAY. DOING SO MAY CAUSE HAZARDOUS VOLTAGE TO BE INDUCED INTO A SET OF MOTOR LEADS EVEN
THOUGH THE DRIVE FEEDING THE MOTOR LEADS IS NOT OPERATING AND HAS POWER REMOVED.
10. Do not run control wiring in the same conduit or wire-way with power
wires. Maintain a minimum separation of 36 inches (1 meter) between parallel conduits carrying input power or motor leads and conduits carrying control wires. If it is necessary for power and control wiring to cross, cross at a 90° angle and maintain as much separation as possible.
11. Insure that the correct voltage source is connected to the AC drive input terminals, as shown in Figure 4.4.1 – 4.4.4, not the output terminals. Connecting a drive to the wrong voltage can cause equipment mis- operation and/or failure resulting in a safety hazard. Connecting AC line voltage to the output terminals will destroy the drive and void the warranty. Connect a ground wire to the terminal provided at the top of the drive. The motor ground should be tied to the same grounding point.

CAUTION
INSURE THAT THE VOLTAGE OF THE AC DRIVE POWER SOURCE MATCHES THE VOLTAGE RATING OF THE DRIVE NAMEPLATE. CONNECTION OF AN INCORRECT VOLTAGE SOURCE MAY RESULT IN MISOPERATION AND/OR FAILURE OF THE AC DRIVE AND MAY RESULT IN A SAFETY HAZARD. DO NOT CONNECT AC LINE POWER TO OUTPUT TERMINALS (T1, T2, T3).
12. Avoid the use of a contactor between the AC drive and motor. If it is absolutely necessary to install a contactor between the drive and motor, the contactor must be sequenced so that it is closed before the drive receives a run command and remains closed at all times during drive operation. Improper operation of an output contactor may cause the drive to fail and void the warranty.
4.4.2 IGBT Rated Motors
Operation of IGBT based AC drives such as MD200 drives can result in transient voltages that can be damaging to motors under some conditions. The potential for damage increases as the cable length from the drive to the motor increases. Motors used with MD200 drives should be Inverter duty and suitable for use with IGBT drives. Most motor manufacturers have motor designs suitable for application on IGBT inverters. All Sumitomo Machinery Corp. of America SM-Cyclo® F-frame Gearmotors shipped after August, 1996 are suitable for use on IGBT Inverters. Even though a motor may be IGBT rated, cable length between the motor and drive should be minimized. Refer to Table 4.1 on the following page for recommendations.
If an MD200 drive is installed to operate an existing motor that is more that two years old and/or the motor was previously controlled by a fixed-speed starter, it is highly unlikely that the motor is equipped with IGBT rated insulation. In this event, operation of the drive could result in failure of the motor. A line reactor or transient voltage suppressor installed between the drive and motor may provide the necessary protection. A suggested source of these components is:

The information above is based on data provided by Marathon Electric, Wausau, WI and may not be applicable to all motors. Sumitomo Machinery Corporation of America F-Frame Integral Gearmotors are IGBT rated.
4.4.3 Control Wiring
1. All control signals interfacing with the MD200 AC drive must be connected using shielded cable. Analog signals for 0 to 10 VDC, remote speed potentiometer or 4 to 20 mA should be run in shielded, twisted-pair cable. Cable shields for drive inputs must be grounded only at the drive end. The drive chassis is considered ground provided the power supply ground wire is properly terminated at ground screw. A jumper can be placed between any terminal labeled TB2 and chassis ground. All TB2 points are internally connected to each other. Note: TB2 must be connected to chassis ground when terminals TXA and TXB are used for RS485 serial communications. Cable shields for drive outputs must be grounded only at the connected device end.
2. Any relay, contactor or solenoid coil located near the drive, connected to the drive or fed from the same power source as the drive must be
equipped with a transient suppressor on its coil. Consult the device manufacturer for recommended suppressors.
3. A DC relay coil connected to one of the open collector transistor outputs must be equipped with a flyback diode transient suppressor. The diode must be connected so that its cathode terminal is oriented toward the positive side of the DC voltage. Refer to Figure 4.4.5 below.
R TB-11 (+12V) TB-14 TB-2 COM Figure 4.4.5 DC Relay Coil Connection
Note: Terminal TB-11 can source 12 VDC at 50 mA maximum.
4. Refer to Figure 4.4.6 below to become familiar with the drive control
terminal strip. Observe the following when connecting to the control terminal board:
• Strip wires approximately ¼ in (6.5 mm).
• Control wiring should be twisted, shielded cable with cable shield grounded to the drive chassis.
• Digital Input DI1 must be connected to common (CM) for the drive to operate except when Jog Forward or Jog Reverse is selected as the function for Digital Input DI4 and the input is connected to common (CM).

Figure 4.5.5 – Brake Motor Control
1. A separate brake relay circuit must be used to energize the brake coil. The circuit must be powered from the AC line and not the AC drive output.
2. The open collector transistor output at TB14 must be programmed for Run to allow a brake to release when the drive starts and to allow the brake to set when the drive stops.
3. This set up is not suitable for applications that involve vertical lifting as no provisions are available to insure that motor torque is available prior to releasing the brake. For these applications, use the NTAC-2000 or AF3100α AC drives.
4.6 Explosion-Proof Applications
MD200 drives may be used with an explosion proof motor provided that the motor is UL Listed for use with an AC drive. It must specifically list the Class, Division and Group which is compatible with the location where it will be installed and must include the operating frequency range on its nameplate. Use of the drive with a motor that is not specifically approved for inverter duty will void the listing conditions and may create a safety hazard. Determination of the suitability of the drive and motor combination is the sole responsibility of the user.
5.0 Start-Up Instructions
!
CAUTION
INSURE THAT THE VOLTAGE OF THE AC DRIVE POWER SOURCE MATCHES THE VOLTAGE RATING OF THE DRIVE NAMEPLATE. CONNECTION OF AN INCORRECT VOLTAGE SOURCE MAY RESULT IN MISOPERATION AND/OR FAILURE OF THE AC DRIVE AND MAY RESULT IN A SAFETY HAZARD. DO NOT CONNECT AC LINE POWER TO OUTPUT TERMINALS (T1, T2, T3).
!
CAUTION
TO AVOID DAMAGE TO THE DRIVE, DO NOT APPLY AND REMOVE POWER FROM THE DRIVE MORE FREQUENTLY THAN ONE TIME DURING A TWO MINUTE PERIOD.
!
DANGER
HAZARD OF ELECTRICAL SHOCK OR BURN!
POTENTIALLY LETHAL VOLTAGES EXIST IN THIS DRIVE AND MAY REMAIN AT A DANGEROUS LEVEL FOR SEVERAL
MINUTES AFTER POWER IS REMOVED. BEFORE
ATTEMPTING TO SERVICE THIS CONTROLLER, WAIT 3
MINUTES AND MEASURE THE DC BUS VOLTAGE TO INSURE THAT IT IS ZERO.
5.1 Before Applying Power
1. If the drive has not been energized for a long period of time (generally over one year) due to storage or inactivity of the application, the dielectric material of the DC bus capacitors can begin to degrade. The dielectric must be “re-formed” by applying power for 2 hours prior to operating the motor. Failure to reform the dielectric can result in higher than normal leakage current in the capacitor and premature failure of the capacitor. 2. Insure that all wiring is completed in accordance with this manual and
applicable electrical codes. Verify that the input power leads are routed to the proper terminals.
3. Verify that the input voltage and phase matches the drive specifications on the nameplate or in the Specifications section of this manual.
4. Verify that the connected motor ampere rating does not exceed the rated output current for the drive. Also verify that the motor windings are configured for the proper voltage.
5. Insure that proper fusing is installed in the power circuit feeding the AC drive.
6. If the driven load can be damaged by reverse rotation, uncouple the motor from the load.
5.2 Applying Power For the First Time
!
DANGER
HAZARD OF FLASH BURN OR EYE INJURY!
DO NOT STAND DIRECTLY IN FRONT OF THE DRIVE DURING THE APPLICATION OF POWER. INSURE THAT THE
ENCLOSURE DOOR OR COVER IS CLOSED AND SECURED. 1. Never stand directly in front of any electrical power device as power is
applied. Miswiring or connection of the wrong voltage can result in
catastrophic failure and hazardous release of energy. Close and securely fasten the enclosure door or secure the enclosure cover. The use of approved safety glasses is strongly encouraged.
2. Close the disconnecting means to apply power to the drive.
3. Open the enclosure door or cover to view the LED display on the front of the drive. If the drive is not receiving a run command, the LED display will indicate as shown below in Figure 5.2.1.
Figure 5.2.1 Display w/Drive Stopped
The 3 center segments of the LED display are illuminated which indicates that the drive is stopped.
Note: If you watched the drive power up in spite of the advice to the contrary, the LED will flash a number briefly. This number indicates the parameter set loaded in the drive.
5.3 Checking Motor Rotation
The following procedure assumes that the drive has been powered up for the first time and that none of the factory settings have been modified.
1. Press and hold the ∇ button to decrease the frequency setpoint to 00.0 Hz. The left Status LED will illuminate as the setpoint is decreased. The frequency will decrease in 0.1 Hz increments until the next whole Hz value is reached and it will then decrease in 1 Hz increments until the button is released or 0 Hz is reached.
Once 0 Hz is reached, the display will toggle between “00.0” and “- - -“ which indicates that the drive is stopped and zero Hz is commanded. 2. Give the drive a run command as shown in one of the wiring diagrams
shown in the Installation Section. Once the run command is received, the display will show a steady indication of “00.0” which indicates that the drive is in a run state and has a frequency command of 00.0 Hz.
3. Use the ∆ button to increase the frequency setpoint until the motor begins to rotate. The left Status LED will illuminate as the frequency setpoint is increased. If the ∆ button is held continuously, the frequency will increase in 0.1 Hz increments until the next whole Hz value is reached and it will then increase in 1 Hz increments until the button is released or maximum frequency is reached.

DANGER
HAZARD OF ELECTRICAL SHOCK OR BURN!
POTENTIALLY LETHAL VOLTAGES EXIST IN THIS DRIVE AND MAY REMAIN AT A DANGEROUS LEVEL FOR SEVERAL MINUTES AFTER POWER IS REMOVED. BEFORE
ATTEMPTING TO SERVICE THIS CONTROLLER, WAIT 3
MINUTES AND MEASURE THE DC BUS VOLTAGE TO INSURE THAT IT IS ZERO.
4. Check the direction of rotation. If the direction is correct, no further action is necessary. If the direction is incorrect. Stop the drive by removing the run command. Remove power from the drive, lock out the disconnecting means and wait for the DC bus capacitors to discharge. Reverse any two of the motor leads connected to terminals T1, T2 or T3 of the drive. Note that reversing the input power leads cannot change the direction. The drive is phase insensitive to the incoming power.
5. If the motor was uncoupled from the load during the rotation direction test procedure, remove all power from the drive and install safety lockout devices as required by electrical codes and good safety practices. Reconnect the motor mechanically to the load.
5.4 Finishing the Start-up
Some programming of the drive will generally be required to optimize the drive’s performance in the application. Programming details are covered in Section 6, Programming. Some things to be considered are:
• Acceleration / Deceleration Time
• Use of Analog Input for Speed Command • Configuring the Programmable Digital Inputs • Setting Motor Overload Protection
It is strongly recommended that the entire programming section be studied before attempting to change any parameters. The few minutes spent doing this can save considerable time and headaches when trying to set the parameter values.
6.0 Programming the MD200 Drive
Programming the MD200 drive is simple once the proper technique described below is learned. The drive may be programmed by one of three methods. 1. Using the 3 buttons and LED display on the front of an open chassis drive
(or the Operator Interface Module if the optional remote operator device is purchased or a NEMA 1 drive is supplied).
2. Programming the Electronic Programming Module (EPM) using the optional Portable Programming Fixture.
3. The RS-485 port standard on MD200 drives.
These instructions assume that the programming buttons on the front of the drive are being used. Refer to Section 1, General for a description of the operator interface symbols used in this manual.
6.1 Basic Programming Steps
1. Enter the Program Mode. Enter the programming mode by pressing the Mode button on the front of the drive. This will activate the password prompt. Note: If setting the password value in parameter 44 to zero has disabled the password, this step will be skipped. The right Status LED will blink to indicate that the drive is waiting for the password to be entered.
Press Mode
Display Reads “00” Right Status LED Blinks Password Prompt
2. Set the Password. The Password consists of 3 digits that must be entered using the ∆ and ∇ buttons. The factory default password is 225.
Use the ∆ and ∇ buttons to scroll the display until the correct password value is set. Any number from 001 to 999 may be used. The factory value is 225. Setting a value of 000 in parameter 44 disables the password.
3. Enter the Password. Press the Mode button to enter the password set in the previous step.
If an incorrect password was entered, the display will show “Er” for a few seconds as shown below and the password entry process must be repeated from the beginning.
Display after incorrect password entry.
Invalid Password Entry
Otherwise, the programming mode is entered as confirmed the display changing to “P01” which indicates the beginning of the parameter menu. This condition is shown below.
Valid Password entered.
Display indicates first parameter number. Use ∆ and ∇ buttons to scroll parameters. Valid Password Entry (or No Password Set) – Parameters Unlocked
Note: After about 2 minutes of inactivity, parameter access locking will be reestablished and reentry of the password will be required. This can be avoided, if desired, by setting the password value in parameter 44 to 000. 4. Select the parameter. Use the ∆ and ∇ buttons to select the desired
parameter number. Refer to Section 6.4 for a listing of parameter numbers. The example below shows Parameter 19, Acceleration Time.
Use the ∆ and ∇ buttons.
Display indicates parameter number. Parameter Number Selection
5. View the parameter value. Press the Mode button while the desired parameter number is displayed. This will cause the Right Status LED to begin blinking. The current value of the parameter is displayed. Refer to the example below.
Press the Mode button
Parameter Number Action Parameter Value The example above shows parameter number 19, Acceleration Time, with a value of 20.0 seconds.
6. Change the parameter value. While the Right Status LED is blinking, the value can be changed using the ∆ and ∇ buttons. Each press will
increment the value by one or continuous pressure on the button will cause the value to scroll up or down.
7. Save the parameter value. Press the Mode key to save the new value, or if no changes were made, restore the old value. Note that this also automatically exits the programming mode. If other parameters are to be set, do so within about two minutes to avoid having to reenter the
password.
See Section 6.2 below for additional programming details.
6.2 Setting Parameter Values in Tenths Above 100
Parameter settings, where appropriate, and the keypad speed command can always be adjusted in tenths of units increments from 0.0 to 99.9. Above 100 however, values can be set in whole units or tenths of units, depending on the setting of Parameter 16 - Units Editing.
If Parameter 16 - Units Editing is set to WHOLE UNITS (02), the parameter values and the keypad speed command can only be adjusted by whole unit increments above 100. For example, Parameter 19 - Deceleration Time could not be set to 243.7 seconds. It could only be set to 243 or 244 seconds. Likewise, the keypad speed command (set using the ∆ and ∇ buttons) could not be set to 113.4 Hz. It could only be set to 113 or 114 Hz.
If, however, Parameter 16 - Units Editing is set to TENTHS OF UNITS (01), parameter values and the keypad speed command can be adjusted in tenths of unit increments up to a value of 1000 (above 1000, whole unit increments only). Each push of the ∆ and ∇ button will adjust the value by one tenth of a unit. If the ∆ and ∇ button is pressed and held, the value will increment by tenths of units until the next whole unit is reached, and then the value will increment by whole units.
When a value above 100 is being adjusted by tenths of units, the value is shifted to the left by one digit so that the tenths portion of the value can be displayed. This results in the first digit (reading from left to right) of the value disappearing from the display. Also, the decimal point will blink to indicate that the actual value is above 100. Once the value is no longer being adjusted, the value will shift back to the right and the tenths portion of the value will disappear.
In the example below, assume that Parameter 19 - Acceleration Time is presently set to 243.0 seconds and it is being increased to 243.7 seconds.
Press the ∆ button to display tenths. Present Setting
243 Seconds Action
Parameter Value Shifted Left One Digit Note above that both the Right Status LED and the Decimal Point blink to indicate that tenths are being displayed.
Press the ∆ button seven times. Present Setting
243.0 Seconds Action
New Setting 243.7 Seconds Press the Mode button to save the new value. Note that in the step above, if the ∆ button is pressed and held, the value will begin to increment in whole units after the first whole unit is reached.
6.3 Electronic Programming Module (EPM)
Every MD200 drive has an Electronic Programming Module (EPM) installed on the main control board. With open chassis drives, the EPM is located to the left of the LED display and above the programming buttons. It is visible through the front cover and can be removed by grasping it gently with a pair of needle-nose pliers.
The EPM stores the factory default and the user program settings (and optionally, an OEM’s parameter settings). The EPM must be present for the drive to operate and the drive will display a fault message “F1” if an EPM is not installed. The removable nature of the EPM offers a couple of
advantages. First, if a drive is being replaced with a new unit and the EPM is not damaged, the old EPM can be removed from the drive and installed in the new drive. Second, if many drives are to be programmed with identical
parameter values, an EPM can be copied (using the optional Portable Programming Fixture) or parameter values can be downloaded from a computer into the EPM (again using the optional programmer).
If OEM settings are not used or the data becomes corrupted, the drive will display a “GF” fault if a RESET OEM or use OEM SETTINGS selection is made in Parameter 48, Program Selection. The user must then either select USER SETTINGS to operate with user entered parameter values, RESET 50 to reset to 50 Hz factory defaults, or RESET 60 to reset to 60 Hz factory defaults. The EPM can be removed and reprogrammed with new OEM settings, if necessary.
If the OEM settings, if used, and User settings become corrupted, the user must select RESET 50 or RESET 60 as appropriate for the application.
!
CAUTION
DO NOT REMOVE THE EPM WHILE POWER IS APPLIED TO THE DRIVE. DAMAGE TO THE DRIVE AND/OR EPM MAY RESULT.

6.5 Detailed Parameter Descriptions
01 Line Voltage Selection
MD200 drives have a range of acceptable input voltages. This parameter allows the drive to be configured for the range of voltage that is applied. For example, an MD240-A75 will work over the range of 380 to 480 VAC, however this is broken into 2 ranges, 380 – 415 VAC (Low) and 440 – 480 VAC (High). Setting this parameter for the correct range improves performance of the drive. Refer to the Table 6.1 below for details.
Table 6.1 – Line Voltage Selection Model No. (4th Character) Rated Input Voltage (VAC) Input Phase Actual Input Voltage (VAC) Parameter Setting 110-120 (220-240) 01 (HIGH) MD210-xxx 240/208/120 1 200-208 02 (LOW) 220-240 01 (HIGH) MD220-xxx 240/208 1 or 3 200-208 02 (LOW) 220-240 01 (HIGH) MD230-xxx 240/208 3 200-208 02 (LOW) 440-480 01 (HIGH) MD240-xxx 400/480 3 380-415 02 (LOW) 575-600 01 (HIGH) MD250-xxx 590/480 3 460-480 02 (LOW)
Note: If this parameter is changed while the drive is running, the new value will not take effect until the drive stops.
02 Carrier Frequency
This parameter sets the switching rate of the inverter IGBTs and also controls the drive’s allowed maximum operating frequency. Increasing the carrier frequency will reduce audible motor noise but increase drive losses. Higher carrier
frequencies increase the potentially damaging effects of voltage spikes on motor insulation. This effect worsens with increasing motor cable length.
Parameter Setting Carrier Frequency Max. Output Frequency 1 Ambient or Output Derating 2 01 4 kHz 240.0 Hz (400.0 Hz) 50°C 100% FLA 02 6 kHz 240.0 Hz (600.0 Hz) 50°C 100% FLA 03 8 kHz 240.0 Hz (999.9 Hz) 43°C 92% FLA 04 * 10 kHz * 240.0 Hz (999.9 Hz) 35°C 82% FLA Notes:
1 – As shown in parenthesis, this setting affects the max output frequency of drives with the high carrier frequency option.
2 – Above 6 kHz the drive must be applied in the maximum ambient shown or it must be used at no more than the percent of full load amperes shown. If this parameter is changed while the drive is running, the new setting will not take effect until the drive stops.
03 Start Method
!
DANGER
POSSIBLE INJURY OR DEATH
SETTING THIS PARAMETER TO “02” OR “04” THROUGH “07” MAY CAUSE A MACHINE TO RESTART UNEXPECTEDLY
AFTER A FAULT OR POWER OUTTAGE. THIS VALUE SHOULD NOT BE USED IN CASES WHERE PERSONNEL CAN COME IN CONTACT WITH MOVING APPARATUS.
Parameter 03 Start Method (continued) Parameter
Setting Action Description
01 NORMAL
The drive will start when the appropriate contact is closed on the terminal strip or when the START key on the optional remote keypad (or integral keypad on NEMA 1 drives) is pressed.
02 START ON POWER UP
The drive will automatically start upon application of input power.
03 START WITH DC BRAKE
When a start command is received, the drive will apply DC Brake Voltage (Parameter 22) for the duration of the DC Brake Time (Parameter 21) prior to starting the motor. This is useful to avoid trying to start a motor that may be
coasting.
04
AUTO RESTART WITH DC
BRAKING
The drive will respond as described in START WITH DC BRAKE above with the addition that it will attempt to automatically restart up to 3 times after a fault condition or reapplication of power after a power failure.
05 FLYING RESTART 1
Low performance. Slowest synchronization and lowest current level resulting in the smoothest operation.
06 FLYING RESTART 2
Medium performance. Faster synchronization at a higher current level but maintaining
smooth operation. 07 FLYING
RESTART 3
High performance. Fastest synchronization at the highest current level. Sacrifices
smoothness.
Parameter values 02 and 04 through 07 require that the drive be controlled by a 2-wire (maintained run contact) circuit to be functional. The run contact must remain closed during the restart interval for the Auto Restart function to work. The interval between restarts is 15 seconds for setting 04 and 2 seconds for settings 05 through 07. During the interval between restart attempts the display will read “SP” for Start Pending. If all 3 restart attempts fail, the drive will lock out and the display will read “LC” for Fault Lockout and manual reset will be required.
04 Stop Method Parameter
Setting Action Description
01 COAST TO STOP
When a Stop command is received, the drive immediately shuts off power to the motor similar to opening a magnetic starter. The motor coasts to stop or can be stopped by a mechanical brake.
02 COAST WITH DC BRAKE
When a Stop command is received, the drive will immediately shut off and activate DC Braking (after a variable, non-programmable, delay of up to 2 seconds). The magnitude of the DC voltage is controlled by parameter 22 and the duration is controlled by parameter 21. Frequent, prolonged use of DC Braking may result in motor overheating and possible damage.
03 RAMP TO STOP
When a Stop command is received, the drive decelerates down to stop at the programmed deceleration time (Parameter 20).
04 RAMP WITH DC BRAKE
Similar to “03” above except at 0.2 Hz, DC Brake Voltage is applied for the DC Brake Time to facilitate final stopping of the motor. See parameters 21 and 22.
05 Standard Speed Source
This parameter selects the source of the speed reference when the drive is in Standard speed mode.
Parameter
Setting Function Description
01 KEYPAD Use the ∆ and ∇ keys to set drive frequency. 02 PRESET
SPEED 1
The drive will operate at the frequency set in parameter 31.
03 0-10 VDC Drive frequency is controlled by a 0-10 VDC signal applied between TB5 (+) and TB2 (-). 04 4-20 mA Drive frequency is controlled by a 4-20 mA
06 TB14 Open Collector Output Function
This parameter selects the function for the open-collector transistor output at terminal TB14. Open collector transistors can directly drive the input of most “sinking” type digital inputs of Programmable Logic Controllers or embedded controllers. The power supply common of the external device must be connected to TB2 of an MD200 drive. Open collector transistors can also be used to drive external relays to switch larger loads or loads with higher voltage requirements. When the transistor turns “on”, TB14 is pulled to common and current can flow from TB14 (+) to TB2 (-). Open collector transistors can only be used to switch DC loads.
Parameter
Setting Function Description 01 NONE The output is disabled. 02 RUN
On when the drive is running. Off when the drive stops either normally or due to a fault. This is useful for remote run indication or to sequence a motor mechanical brake.
03 FAULT On indicates normal operation. Off indicates a fault or no power applied.
04 INVERSE FAULT
On indicates a fault. Off indicates normal operation or no power.
05 FAULT LOCKOUT
On during normal operation. Off after three failed restart attempts or if no power is applied. 06 AT SET
FREQUENCY
On if the drive output frequency is between ± 0.5 Hz of the set frequency.
07 ABOVE PRESET SPEED 3
On if the output frequency exceeds the value set in Preset Speed 3 (parameter 33). Off if the output frequency is equal or less than Preset Speed 3.
08 CURRENT LIMIT On if the output current exceeds the Current Limit setting (parameter 25), otherwise Off. 09 AUTOMATIC
MODE
On if an Automatic (terminal strip) speed reference is active. Off if a Standard speed reference is active. See parameter 5.
10 REVERSE On when reverse rotation is active, otherwise Off.
08 TB30 Analog Output
Terminal TB30 provides a 0-10 VDC or 2-10 VDC signal proportional to Output Frequency or Load as selected in this parameter.
Parameter
Setting Function Description 01 NONE The output is disabled.
02 0-10 VDC FREQ 0-10 VDC from 0.0 Hz to parameter 40 value. 03 2-10 VDC FREQ 2-10 VDC from 0.0 Hz to parameter 40 value. 04 0-10 VDC LOAD 0-10 VDC from 0% to parameter 41 value. 05 2-10 VDC LOAD 2-10 VDC from 0% to parameter 41 value. Note: The 2-10 VDC signal can be converted to 4-20 mA by connecting a
resistor in series with the signal so that the total resistance (Resistor + Load Input Impedance) is 500 ohms. The output cannot be used with “Loop Powered”
devices that derive their control power from the 4-20 mA signal.
09 TB31 Analog Output
Similar to TB30 above plus Dynamic Braking module control. Parameter
Setting Function Description 01 NONE The output is disabled.
02 0-10 VDC LOAD 0-10 VDC from 0% to parameter 41 value. 03 2-10 VDC FREQ 2-10 VDC from 0% to parameter 41 value. 04 DB CONTROL Provides the trigger that activates the optional,
external Dynamic Braking module. The same note related to 4-20 mA as shown in TB30 applies.
