Operation

Systems with integrated MOVIDRIVE® MDX61B with DCS31B option must be equipped with additional monitoring and protection devices, if necessary, according to the appli-cable safety guidelines, such as the law governing technical equipment, accident pre-vention regulations, etc.

Keep all covers and doors closed during operation.

The fact that the status LED and other display elements are no longer illuminated does not indicate that the unit has been disconnected from the power supply and no longer carries any voltage.

Mechanical blocking or internal safety functions of the unit can cause a motor standstill. Eliminating the cause of the problem or performing a reset can result in the drive re-start-ing automatically. If, for safety reasons, this is not permitted for the driven machine, dis-connect the unit from the mains before correcting the fault.

Measures to ensure electromagnetic compatibility (EMC)

The DCS31 option is designed for industrial applications (based on the EMC test spec-ifications EN 61800-3). Prerequisite for safe installation is that the electromagnetic com-patibility of the entire system must be ensured by taking appropriate measures. The fol-lowing measures ensure the designated operation of the DCS31B:

• Make sure that the voltage supply lines of the DCS31B option and the "switching cables" of the MOVIDRIVE® MDX61B are routed separately.

• Route the inverter’s signal cables and power cables in separate cable ducts. The cable ducts must be at least 10 mm apart.

• Only use shielded cables to connect the position and velocity sensors. The cable used to transfer signals must be suitable for the EIA485 standard (formerly RS485). • Make sure the shield in the 9-pin sub-D connector for the position and velocity sensors is applied correctly. The shielding on the sensor side must also be applied correctly. Only use metal or metallized connectors.

• Make sure the installation of the inverter is EMC-compliant in the vicinity of the DCS31B. Check the routing and design of the shielding for the motor cable and braking resistor connection.

• All contactors in the vicinity of the DCS31B option have to be equipped with suitable suppressors.

(17)

External DC 24 V voltage supply

4.5

External DC 24 V voltage supply

The DCS31B option requires a DC 24 V voltage supply (SELV or PELV, EN 50178). During project planning and installation of the power supply unit, the following conditions must be taken into account:

• Make sure you adhere to the minimum and maximum tolerance of the supply voltage.

• To keep the residual ripple of the supply voltage as low as possible, we recommend using a 3-phase power supply unit or an electronically-controlled unit. The power supply unit must meet the requirements in EN 61000-4-11 (voltage dip).

• The external DC 24 V supply of the DCS31B option also powers the internal elec-tronics and the external velocity and position sensors. These components are not protected separately against short circuits. The current consumption of the installed encoder should not exceed DC 300 mA. When using encoders with higher operating currents, the encoder voltage supply must be provided separately.

• You must ensure the external DC 24 V voltage supply is isolated from the voltage supply system (e.g. AC 230 V). To do so, choose power supply units that meet the guidelines stipulated in DIN VDE0551, EN 60742 and DIN VDE0160. When selecting a suitable unit, make sure there is equipotential bonding between PE and DC 0 V on the secondary side.

• Provide external protection for the DCS31B option by installing a 2 A fuse. Observe local guidelines when configuring the connection cables.

• The maximum external voltage that can be connected to the DCS31B option is DC 32 V.

4.6

Connecting binary inputs DI1 to DI8

The DCS31B option has 8 binary inputs (DI1 ... DI8). They are suitable for connecting single or dual-channel sensors with or without pulsing.

The connected signals must have a "high" level of DC 24 V (DC +15 V ... DC +30 V) and a "low" level of DC 0 V (DC –3 V ... DC +5 V). The inputs are fitted with input filters. An internal diagnostic function checks cyclically whether the binary functions and the in-put filters are working properly. If an error is detected, the DCS31B option switches to alarm status and displays the error (→ Sec. "Local diagnostics").

Tolerance

Minimum (– 15 %) Maximum (+15 %)

Nominal voltage = DC 24 V DC 24 V – 15 % = DC 20.4 V DC 24 V +15 % = DC 27.6 V

NOTE

To be able to acknowledge error messages, the binary input DI6 must be config-ured as reset input.

(18)

Using clock out-puts P1 and P2

In addition to the binary inputs DI1 to DI8, the DCS31B option has two clock outputs P1 and P2. Clock outputs P1 and P2 are switching DC 24 V outputs installed for monitoring binary inputs (DI1 ... DI8) only. Clock outputs may not be used for other functions of the application. The switching frequency is 240 Hz (stand-alone) for each clock output. For project planning, note that the maximum total current permitted for the outputs is 300 mA.

Each binary input of the DCS31B option can be configured separately for the following signal sources:

• Binary input is assigned to pulse P1 • Binary input is assigned to pulse P2

• Binary input is assigned to DC 24 V continuous voltage

NOTE

Without changing the pulse, the binary inputs can be used with single-channel, self-monitoring sensors in applications according to EN 954-1 to category 2. With dual-channel sensors and a function test performed within 24 hours, two-dual-channel sensors without pulsing can achieve category 4. If a function test is not performed within 24 hours, the sensors can achieve category 3. Note that external measures, particularly suitable cable routing, must be taken to prevent short circuits in the external wiring be-tween different inputs and against the supply voltage of the DCS31B option.

NOTE

The following sample circuits assume that the switching elements are configured in ac-cordance with the required EN 954-1 category and that safety approval has been granted for the application in question.

NOTE

The single-channel sensor is connected to the DCS31B option without pulsing. The DCS31B option cannot detect cross faults or interruptions in the signal line. Note that this configuration is not permitted for safe applications without external measures.

(20)

Dual-channel sensor, unchecked

Before using dual-channel sensors (homogeneous or diversified) check whether they have been approved for the intended purpose.

Using dual-channel homogeneous sensors without a pulsing can lead to problems. Short circuits cannot be detected in the supply line of the dual-channel sensor, e.g. in the cable. Safe operation can only be achieved by routing the cables separately and making sure the terminals cannot short circuit.

The DCS31B option can operate safely with dual-channel diversified sensors without pulsing.

Connecting binary inputs DI1 to DI8

Single-channel sensor, checked

Check whether the sensor is approved for use in fail-safe applications.

When using a single-channel sensor with pulsing, the sensor must be connected to the clock output P1 or P2. The clock cycle must then be assigned on the DCS31B option. The following errors are detected if you use a single-channel sensor with pulsing: • Short circuit in the DC 24 V supply voltage

• Short circuit on DC 0 V

• Cable interruption (power interruption is a safe state!)

However, a short circuit in the cable between the two sensor connections is not detected. A short circuit between P1 and DI1 is also not detected. With a suitable switching element and careful cabling for the sensor, category 3 to EN 954-1 can be achieved.

Category 3 is achieved when there is no possibility of a short circuit between DI1 and P1 or between the sensor connections. Faults can be excluded in accordance with EN ISO 13849-2, table D8.

(22)

Dual-channel sensor, checked

All cross fault connections and connections to DC 24 V and DC 0 V can be detected when two independent clock signals are used on a homogeneous sensor. Only use NC contacts for safety applications.

Connecting position and velocity sensors

4.7

Connecting position and velocity sensors

Before you begin

The DCS31B option has two encoder interfaces for connecting standard incremental, sin/cos and absolute encoders.

Incremental, sin/cos or absolute encoders (binary or Gray Code) can be connected and operated via the same encoder interface. The internal encoder simulation can be used via backplane bus as well. The sin/cos encoders operate in the same way as incremen-tal encoders.

Please read the following notes carefully:

• The DCS31B option usually provides the connected sensors with the voltage supply. This voltage is monitored by a diagnostic process. If the sensors are powered by an external voltage supply. you must include the possibility of a voltage supply failure in the possible sources of error for the whole system. Particularly with shared external voltage supplies, you must document that this fault will be detected when the mini-mum operating voltage of the encoder system is not maintained.

• Check that EMC measures, such as shielding, etc., have been applied.

• The two encoders must not impact on each other. This refers to both the electrical and mechanical part.

• If both encoders are connected to the monitoring system with the same mechanical parts, the connection must be positive and may not include any parts that are subject to wear (chains, toothed belts, etc.). However, if parts subject to wear are used, you must install additional monitoring systems to check the mechanical connection of the sensors (e.g. monitoring function for a toothed belt).

• If position processing is activated, you must use at least one absolute encoder. If you only use one absolute encoder, connect it to X85 (encoder 2) on.

• Encoder 1 functions as a process sensor and encoder 2 as a reference sensor. If you are using encoders with different resolutions, configure the encoder with the higher resolution as "Encoder 1" (X84) and the encoder with the lower resolution as "Encod-er 2" (X85).

STOP!

Do not plug in or remove encoder connections during operation.

Doing so can cause irreparable damage to the electrical components on the encoder. Disconnect the connected encoders and the DCS31B option before plugging in or re-moving the encoder connections.

NOTE

(24)

The following also applies to the use of absolute encoders:

• Absolute encoders can be read in in the data format SSI binary or SSI Gray Code. This setting is made in the encoder dialog box in the configuration software.

• The data length is 24 Bit.

Combining differ-ent encoder types

Encoder types can be combined depending on the specific application. Note the follow-ing limitations:

• If monitoring functions are used with position processing, at least one sensor must be assigned as an absolute encoder.

• When combining an absolute encoder with an incremental encoder, connect the in-cremental encoder to X84 and the absolute encoder to X85.

• If the internal encoder value of the inverter is to be used, the internal encoder has to be configured in the MOVISAFE® CONFIG program as "encoder 1".

• If you change the encoder configuration at a later date, the existing parameters for the monitoring functions may no longer be compatible with the new encoder config-uration. In this case, check the parameter settings and value ranges of all the moni-toring functions in use. SEW-EURODRIVE recommends using the encoders listed in the appendix.

Configuring the measuring types

The most important input parameters for the monitoring functions of the DCS31B option are:

• Position • Velocity • Acceleration

These input parameters are generated in a dual-channel from the connected encoder systems. Two independent encoder systems are required to achieve category 4 in ac-cordance with EN 954-1. One encoder system can be sufficient for certain applications to achieve category 3 in accordance with EN 954-1 (e.g. only velocity monitoring). Travel types A and B must be configured accordingly for internal signal processing. This can be done using the encoder dialog box in the programming interface.

Note the following parameters when configuring the travel type: • Measuring type

You can choose "linear" or "rotary" as the travel type.

Units of the travel type

For a linear measuring type, you can choose "mm/sec" or "m/sec" as the unit for ve-locity. For rotary travel, you can choose "mgrad/sec", "rps" or "rpm" as the unit for velocity. The selected resolution should correspond to the physics of the travel type to prevent rounding problems in the configuration.

(25)

Connecting position and velocity sensors

Positioning range

The positioning range is used to determine the permitted range during positioning processes. If you do not define a positioning range, only monitoring functions with ve-locity processing properties will be activated during configuration. Monitoring func-tions with position processing properties will be deactivated in the dialog box. Once you have activated the positioning range window, i.e. allowed position processing, note that the current position of the drive must be within the measuring length win-dow. The positioning range has a range of 1 ... 1000000 and is normalized with the unit specified for the travel type.

Encoder type

The following encoders can be used: Absolute encoder:

– SSI data interface with a constant data length of 24 Bit – Binary or Gray Code data format

– Encoder with signal level to RS422

– If the measuring channel is operated in slave mode, i.e. as a listener, the maxi-mum external clock rate is 150 kHz. The pulse break between the pulse clusters must be greater than 30 µs and less than 6 ms.

Incremental encoder:

– Encoder with signal level to RS422

– Measuring signal A/B track with 90 degree phase difference – Maximum frequency of the input pulses 200 kHz

Sin/cos encoder:

– Encoder with AC 1 Vss

– Measuring signal A/B track with 90 degree phase difference – Maximum frequency of the input pulses 200 kHz

Internal encoder simulation via backplane bus:

– The signals of the motor encoder can be used as encoder 1.

– The number of pulses of the encoder simulation via backplane bus is 4096 pulses per revolution after starting up the encoders in MOVIDRIVE®.

Safety-related switch-off thresholds

The basic check is to perform a plausibility test between the two measuring channels A and B of the DCS31B option to compare the current position and velocity values with the configurable thresholds.

NOTE

If the internal encoder simulation via backplane bus is used for reference travel of MOVIDRIVE® B, the DCS31B option issues the error message "Plausibility position detection" (F109, subcode 036/037). Acknowledge the error message via the binary input DI6 with fixed "Reset"assignment (→ Sec. 4.6).

Conversion example

The ramp times of the MOVIDRIVE B inverter are based on a setpoint step change of

Δn = 3000 1/min. The acceleration value a is calculated using the following formula:

Example: In MOVITOOLS®, P137 Emergency ramp is set to 2 seconds.

Conversion to 1/s2:

The values entered in the MOVISAFE® CONFIG program are based on the travel type. This means that the motor revolutions still have to be converted to the travel type. • Rotary system:

NOTES

• For connection of an encoder to both a MOVIDRIVE® B and the DCS31B option, you can order a prefabricated cable from SEW-EURODRIVE under the part num-ber 1810 053 8.

• The prefabricated cable allows you to split the encoder signals and to connect the encoder to the options DCS31B and DEH11B. The following encoder types can be connected:

• Incremental encoder • Sin/cos encoder

• Hiperface® encoder (only the sin/cos tracks are evaluated)

One-encoder con-cept

For applications in category 3 it is possible to use only one encoder. In this case, the signal outputs of the encoder are split between X15 of the DEH11B option and X85 of the DCS31B option (→ following figure). The internal encoder simulation via backplane bus can be used as encoder 1.

The operating system of the DCS31B option detects the following faults of the external encoder system.

• Short circuits between the safety-related signal lines • Interruptions in the safety-related signal lines

• "Stuck at 0" or "1" on one or all safety-relevant signal lines • Rectangular oscillation caused by in-phase signals

59388AXX

NOTES

• Limitations apply to planned encoder systems for applications with one encoder system in sin/cos signal form in category 3. The errors listed below are detected in the external encoder system and in the wiring by using internal diagnostic mea-sures. Mechanical faults such as shaft breakage and slip are not detected and have to be ruled out by appropriate measures in the system design. Faults within the encoder (electrical and mechanical) have to be considered individually depend-ing on manufacturer and type and examined with respect to ruldepend-ing out faults. • The design of the mechanical system and of the encoder must be subjected to a

Wiring of binary outputs

If the used encoder is not listed, you have to take a closer look at possible faults of the used encoder and qualify them within the context of an FMEA.

4.8

Wiring of binary outputs

The DCS31B option has a total of 6 binary outputs, which can be used individually or combined in groups.

The binary outputs are subjected to a plausibility test in all operating states. When switched on, the binary outputs are tested for correct functioning with a cyclical test pulse. The binary outputs are switched to their inverse value for the duration of the test (< 100 µs), i.e. a P binary output is switched briefly to DC 0V potential, and an M binary output is switched briefly to DC 24 V potential.

The binary output test function is performed for group and individual control.

(38)

P554 CRC DCS Display value that cannot be changed.

The parameter CRC DCS displays the CRC (cyclic redundancy check) of the program stored on the DCS31B option. You have to enter the CRC in the validation report (→

Sec. "Validation").

P555 DCS error response / P556 DCS alarm response

Factory setting: IMM. STOP /FAULT

If the DCS31B option issues a fault (P555) or an alarm (P556), the inverter performs the set response.

The following responses can be programmed:

P557 DCS actual position source

Setting range: Motor encoder (X15) / ext. encoder (X14) / absolute encoder

If the option "Encoder inverter" is set as encoder 1 in the MOVISAFE® CONFIG config-uration software, the setting in P557 determines which encoder signal is evaluated by the DCS31B option.

Validation report

To make sure that the implemented safety functions function correctly, the user must check and document the parameters and connections after startup and configuration. This is supported by the MOVISAFE® CONFIG configuration software.

You can call up the validation report directly from the programming interface under the menu item [File] / [Configuration report].

You can use the first page of the validation report to enter generation information on the system (type system, customer, supplier, setup operator, etc.). You can use the second page to enter more detailed information on the system / machine. This data is for infor-mation only, but the content and scope must be checked with the approval authorities / inspector.

The last page of the report contains an itemization on the safety check. You must make the following entries here:

• Serial number (identical to the serial number on the nameplate)

• Correspondence between the serial number read off and the serial number on the nameplate of the DCS31B option

• Identity of the subassembly

Here, the inspector of the safety subassembly confirms that the CRC displayed in the programming interface is identical to the one in the DCS31B option. This CRC sig-nature comprises a five-digit number that is displayed in the connection dialog box of the configuration tool in the diagnostic system information section. In this case, the DCS31B option must have an active connection.

Once all header data has been entered, you can generate the validation report by press-ing the "Save" button. The configuration tool creates a text file (.TXT) with the file name of the parameter/parameter dataset. The text file includes the following information: • The 3 pages of the header data listed above

• Encoder configuration

• Parameters of the monitoring functions

Monitoring functions not required are also listed. These functions must also be checked!

NOTES

• The correct program data and parameter data must be loaded to create the valida-tion report.

• All listed parameters and program instructions must be validated at the system / machine and confirmed by a signature in the validation report.

• The inspector must validate all the configured data again in a printout of the valida-tion report.

• All limit values set for the monitoring functions must be tested. • The printed out AWL code must be validated.

Procedure

Validation

6.1

Procedure

The concept for the DCS31B option is based on the following prerequisites:

Parameter and PLC data stored in the DCS31B option flash memory cannot change au-tomatically. Online tests and corresponding signatures make sure that this is the case by implementing basic measures on the subassembly. However, the configured param-eters cannot be evaluated by the subassembly. This affects paramparam-eters for the sensors, thresholds and limit values.

The user must confirm that the data in the test protocol matches the parameters in the subassembly. The user must validate and protocol the parameter values for the travel type, sensors and monitoring functions individually by performing a function test. In ad-dition, the user must validate and protocol the connection of each programmed PLC function by inspecting the code.

The MOVISAFE® CONFIG configuration software generate a suitable output form and stores it in a text file.

The program enters the following information in the text file: • Manufacturer: SEW-EURODRIVE GmbH & Co KG • Type: DCS31B

• Version of the hardware and activated functions

You must enter the following data in the text file:

• Serial number (identical to the serial number on the nameplate)

• Correspondence between the serial number read off and the serial number on the nameplate of the unit.

The text file can then be printed out. Any other entries must be made manually: • Date the configuration dataset was created
