Recommended motor voltages and field voltages

• Motor voltage UA when the following units are used

DCS 601: UAmax = Line voltage * 1.16 (2- quadrant unit)

DCS 602: UAmax = Line voltage * 1.05 (4- quadrant unit)

• Field voltage UF (= max. output voltage) when the following is being used

SDCS-FEX-1: UF = Line voltage * 0.9

If there is a divergence of more than 10 % between the field supply unit’s output

voltage and the rated field voltage UFrated stated on the motor’s rating plate, then the

connecting voltage UN should be reduced, using a matching transformer or a series

resistor Rv: Rv = (0.9 * UN - UF) / IF IF = Rated field current

(Note: also suitable for fine-balancing the maximum motor voltage)

• Field voltage UF when the following is being used

SDCS-FEX-2 /

DCF 503 / DCF 504: UF = Line voltage * 0.6 ... 0.8

• Field voltage UF when the following is being used

DCF 601: UF = Line voltage * 0.5 ... 1.1

Maximally possible output voltage UAmax using

DCF 601 / DCF 602: UAmax = Line voltage * 1.35

Phase sequence when connecting to the mains / Potential isolation

No special phase sequence required for the main connections U1, V1 and W1!

Phase coordination between electronics section and power section not necessary!

For potential isolation and for avoiding ground loops, an isolating transformer should be

installed upstream when an oscilloscope is being used.

Preventing unintended operating states / Shutting the drive down

CAUTION! As laid down in DIN 57100 Part 727 / VDE 0100 Part 727 (Preventing

unintended operating states), shutting the drive down by means of the

signals at the binary inputs DIx is not sufficient in itself as the sole

measure involved for avoiding unintended operating states or shutting

the drive down in the event of danger!

Range of application for the Start-Up Instructions

The Start-Up Instructions are referenced to the parameter settings in their as-delivered

condition (default values) and to the unit wiring as shown in the connection diagram

(see System description DCS 600).

These Operating Instructions only describe the start-up procedure via panel CDP 312

when in LOCAL mode or/and via PC program DRIVES WINDOW.

Method of functioning of the binary input DI5

• Binary input DI5; designation EM STOP

The binary input DI5, e.g. terminal X6:5 of control board SDCS-CON-2, must be

set to logical "1” in order to get no operation of the EMERGENCY STOP function.

This configuration takes into account the requirements of a fail-safe-circuit.

The incoming signal is inverted by means of the Parameter 13.12 thus setting the

internal signal EMERGENCY STOP to logical "0”. If the external signal is "0”,the

EMERGENCY STOP function will be active and the alarm signal A 102 will appear.

The drive will react in accordance with the setting of Parameter 21.04 EME_STOP_

MODE (presetting is: 1 = STOP WITH RAMP). The ramp time is set by Parameter 22.04. After resetting of the signal, i.e. external signal set back to

logical "1”, the ON command has to be repeated.

Software identification

The software identification of the SDCS-CON2 board is in parameter 4.11.

The software identification of the SDCS-AMC-DC board is in parameter 4.2.

The application identification from ABB Lampertheim is [DCS600xx] in parameter 4.3.

Different coded applications are handled and supported from local ABB organizations.

The software of the units series DCS 600 is divided into two parts which are handled

by processors integrated in the respective boards SDCS-CON-2 (Software 15.2xx) and

SDCS-AMC-DC (Software 15.6xx).

The upload of signals from SDCS-CON-2 to SDCS-AMC-DC board are operated by:

• 6 automatic channels

• 11 programmable channels, selectable in group 94 (see Software description - chapter

31)

The 6 automatic channels are used by the functions:

• Display signals at control panel CDP 312

• Monitor signals at DriveWindow Tool

• Data Logger at DriveWindow Tool

If

• more than 6 signals of the SDCS-CON-2 board are selected, or

• the function Signals and Parameter of DriveWindow, or

• the overriding control (AC 80, AC 70…)

is used for monitoring, the signals should be selected in group 94.xx

Note: In the below mentioned tables AMC / CON-2 will be used as type designations

instead of SDCS-AMC-DC / SDCS-CON-2.

• Fixed (defined) values

Cyclic transmission is used for fixed values. Fixed values are:

Cyclic transmission Parameter Function Cyclic transfrom --> to mission time

AMC --> CON-2  Internal Control Word 2 ms

AMC --> CON-2  Reserved 2 ms

AMC --> CON-2 2.13 Torque reference value 2 ms

AMC --> CON-2 5.06 Analogue output 1 2 ms

AMC --> CON-2 5.07 Analogue output 2 2 ms

AMC --> CON-2  Local reference 3 8 ms

2.1 Preparatory work

Check the unit for damage in transit or other damage.

Install and wire unit; connect all inputs and outputs required.

Proceed in the same way for the field supply unit as well.

Check whether protective measures, earthing, screening, etc. have been taken in

accordance with the system conditions involved.

Check the rated value of the supply voltage for the electronics and the fan:
