2.6 Control, Trip, Emergency operation

Drive logic DCS 600

DCS 600 Manual for 12 – Pulse Operation
The basic switch on/off logic (control structure, see
based on DCS 600 six – pulse converter logic. However for
DCS 600 in 12 – pulse / sequential operation an additional function
is available:
The drive can be commissioned without APC /AC80 control soft-
ware and switched on only by DriveWindow. Moreover the 12 –
pulse configuration can be controlled only by fieldbusadapter mod-
ules (FCI...).
Note: The features for single 6 – pulse operation remain
unchanged.

*) X16 is connected but will only be used in case of slave emergency operation!
This new function is performed by the Parameter COMMAND SEL
. The slave must be set to 12 – pulse link (new value).
(15.22)
With this configuration the APC/AC80/FCI or DriveWindow controls
the complete 12 – pulse configuration.
The signals ON/OFF, START/STOP, REFERENCE and RESET are
sent only to the master.
Parameters (controller gain, motor ratings, operation mode.....)
must be sent directly to the slave converter via CH0 or CH3 (similar
DCS 600 six – pulse).
The controlword MCW
configuration, because the slave receives the command bits by 12–
pulse link (V260).
DriveWindow uploads and displays the slave Status via CH3 auto-
matically. In case of remote operation the overriding control must
upload the slave status via Ch0.
An emergency operation can be used in case of a break down of a
converter. The parameters for 6-pulse single operation mode
(emergency operation) can be sent by DriveWindow (CH3) or over-
riding control (CH0) to the master or slave converter.
