5-29 890SD Standalone Drive
890CS Common Bus Supply - Frames B & D; 890CD Common Bus Drive and 890SD Standalone Drive - Frames B, C & D
4.1: Power-up with 24V DC
You must provide an external 0V and +24V DC (±10%)
control supply. Each unit can draw 2A, so for example: 3
units = 6A.
Connect 24V DC to terminal X13/01 or X13/02, and 0V
(24V) to terminal X13/03 or X13/04. The units are
protected against reversal of this 24V DC supply.
Use the spare X13 terminals to daisy-chain the control
supply to other drives in the system.
The diagram shows the control supply daisy-chained
between 890SD Standalone Drives.
IMPORTANT This Control Supply will power the unit for
configuration purposes. It is not required when the 3-
phase supply is present, but can be left connected.
