Function Description

1. Function Description

The interface board SE21.2 is designed in the SIMADYN D system as an interface between the PS16 digital control and the converter power section of a SIMOVERT S or SIMOVERT D drive (inverter motor or cyclo-converter). It converts and prepares the current and voltage actual values from the converter to SIMADYN D signals or signal groups.

The board can process a maximum of 6 actual value signals. The three phase actual value systems U1, U2, U3 and I1, I2, I3 measured from operation of a cyclo-converter are supplied via X1 . The two phase actual value systems U1, U2 and I11, I12, measured in connection with a inverter motor, is fed via X1 as well as for 12 pulse operation I21 and I22 via X2 . The set-up of the corresponding mode of operation is implemented via the coding plug X250 as well as via solder bridges.

The actual value transducer signals are matched via plug-in burden modules (SE24.1) and subsequently V/F converted (V/F converters = voltage to frequency converters). Three phase absolute values are used for the individual actual value systems, whereby the third phase, for SIMOVERT S, is calculated from both the measured phases. Overcurrent and overvoltage signals are derived from monitoring these values for their limits and frequency signals generated through V/F conversion (only for both current systems for SIMOVERT S). If, in the case of cyclo-converters, the currents are acquired as absolute values, then the absolute values are inverted via binary inputs and made available to the control system with the correct polarity.

There is complete galvanic isolation between the SIMADYN D side and the converter side. The binary signals are isolated via opto-couplers and the frequency signals by trigger pulse transmitters.

All actual values and binary signals as well as the supply voltages are short circuit protected and decoupled. They are available at the connector X4 for diagnostics, display and monitoring purposes (actual values in analog form and not as frequency signals).

The released version of the board is upwards compatible to the previous board version SE21.1 (6DD1681-0CB1) with the following restrictions:

a) The pins 3 and 4 on the burden module are no longer connected to 2M . Application with single pin sources, where this is necessary, require the corresponding connector pins X1: Z4, Z8, Z12, Z20, Z24 or X2: Z16, Z20 to be connected to 2M . 2M is connected to X1: b6, b10, b14, b18, b22, b26 and X2: b18, b22 .

b) The designations of the components on the board have been changed. Replacement of a SE21.1 with a SE21.2 requires the equipment documentation to be updated.

c) If un-used terminal or connector pins on the SE21.1 board have been used as common points, then they must be compared with the pin allocation on the SE21.2 .

(Several terminals and connector pins have been additionally used on the SE21.2 for new functions).

Board Design

2. Board Design

- 6 Analog inputs for actual values with differential amplifiers - 3 binary inputs for polarity switching

- Summation for calculation of the third phase for two phase measured systems

- Limit value generation for determining the overcurrent and overvoltage - 8 Frequency outputs for actual values (galvanic isolation)

- 3 binary outputs for limit values (galvanic isolation)

- 21 Diagnostic outputs, short circuit proof, decoupled (non isolated) - Actual value adaptation via the plug-in burden modules SE24

- Set-up for SIMOVERT D or SIMOVERT S via coded plug and solder bridges - For SIMOVERT S: overcurrent message via binary input switchable limit values

- For SIMOVERT D: Selection input with voltage divider, differential amplifier and frequency actual value. Calibration circuit for V/F channels as a sub-module.

3. Application Notes

- Default Setting

The board set-up is implemented for the required application by cutting connections in the coding plug X250. The connection between the following pins in the plug are to be cut:

- Cyclo-converter application Pin 2 - Pin 15

Pin 3 - Pin 14 Pin 6 - Pin 11

- Inverter motor application Pin 1 - Pin 16

Pin 4 - Pin 13 Pin 5 - Pin 12

- Power Supply

The board power supply can either be fed via the connector X5 and X6 on the front panel or via the back plane connector X9.

- Burden module 6DD 1681-0CE1

(Circuit diagram in the equipment block diagram)

The burden module can be implemented as a voltage divider for actual value transducers with constant voltage output or as a simple burden for transducers with constant current output. The resistor R1 must be jumpered when transducers with constant current output are used.

! WARNING: maximum permissible power loss per load resistor is 2W when resistors of type G204 are used!

(9)

Application Notes

The potentiometer R7 can be used for fine calibration when activated by the series resistor R6 .

! WARNING: The potentiometer current must not exceed 20mA!

The influence of the potentiometer on the divider resistance should be kept as small as possible because of it's relatively high temperature coefficient of ±100ppm/deg.C .

- Actual Values

Three contacts with +24V, -24V and the corresponding reference (ground) potential M are allocated to each actual value channel on the connectors X1 and X2 . Therefore it is possible to supply the transducers via these connectors. The addition current requirement is therefore to be taken into account when configuring the SE21.2 .

The 6 burden modules are allocated the following actual values: SIMOVERT S SIMOVERT D Burden module in Plug Designation

U1 U1 X122 and X269 A1 U2 U2 X10 and X141 A2 I11 I1 X72 and X175 A4 I12 I2 X170 and X280 A5 I21 I3 X294 and X392 A6 I22 U3 X427 and X523 A3

The following is valid for the signal Ua at the burden module and the output frequency: Ua = -10 ... 0 ... +10 V corresponds to f = 30 ... 60 ... 90 kHz

The input of the corresponding burden module must be shorted when the actual value is not used (i.e. by a jumper via R2 of the burden module).

- Switching Polarity

The absolute values of currents I1, I2 and I3, measured through the installed SE21.2 and in connection with a cyclo-converter, can be inverted through three binary inputs via the X6 connector when these values are required in the correct polarity by the control system. The following is valid for these inputs, which are at SIMADYN D potential level:

Inputs 'Low' or open - Current actual value unchanged Inputs 'High' - Current actual value inverted

- Overcurrent or Overvoltage Signals

The comparator thresholds for detecting overcurrent or overvoltage in the two (three) three phase systems are set, in matched burden modules, to 1.38% ± 7% of the signal rated value (signal rated value corresponds to 5 Veff).

! WARNING: The maximum permissible input voltage range for AC voltage is 10 V / 2 = 7.07 V(eff). The limit value indicator board reacts to peak values and not to average values.

(10)

Application Notes

The overcurrent thresholds can be commonly switched via a binary input for SIMOVERT S applications.

The thresholds can be altered between 0 V and +15 V via the following voltage divider. The resistance values set in parentheses are the default installed values.

SIMOVERT S SIMOVERT D Resistance on +15 V

Resistance on 0 V | U1 ,U2 ,U3 | | U1,U2,U3 | R 502 (11 K) R 499 (10 K) | I11,I12,I13 | | I1,I2,I3 | R 506 (11 K) R 509 (10 K) | I21,I22,I23 | --- R 448 (11 K) R 513 (10 K)

! WARNING: The supply tolerance of the +15 V is ±5 %. This should be taken into account when setting the threshold values.

- Diagnostic Outputs X4

The diagnostic outputs can be accessed by installing a 40 pin ribbon cable and the SE23 terminal block.

- Frequency Signals for Absolute Values:

The absolute signals are scaled like the input signals. This signifies that when the actual values are loaded at 5 V(eff) = 100 %, then the absolute signals 5 V = 100 % average value.

ECB instructions

7. ECB instructions

Components which can be destroyed by electrostatic discharge (ECB)

Generally, electronic boards should only be touched when absolutely necessary.

The human body must be electrically discharged before touching an electronic board. This can be simply done by touching a conductive, grounded object directly beforehand (e.g. bare metal cubicle components, socket outlet protective conductor contact.

Boards must not come into contact with highly-insulating materials - e.g. plastic foils, insulated desktops, articles of clothing manufactured from man-made fibers.

Boards must only be placed on conductive surfaces. When soldering, the soldering iron tip must be grounded.

Boards and components should only be stored and transported in conductive packaging (e.g. metalized plastic boxes, metal containers).

If the packing material is not conductive, the boards must be wrapped with a conductive packing material, e.g. conductive foam rubber or household aluminum foil.

The necessary ECB protective measures are clearly shown in the following diagram.

a = Conductive floor surface d = ECB overall

b = ECB table e = ECB chain

c = ECB shoes f = Cubicle ground connection
