If the direction of rotation of the motor is wrong,
it can be corrected by swapping the terminal
connections on two of the phases at the drive
module end of the cable.
The DC bus terminal is used for DC back-up with
the Intermediate circuit being supplied from an
external source.
The DC-DC board power supply cable should be
connected to the Regen terminals with access
from the bottom side. The ModBus and Interlock
cable harness should be routed properly from the
bottom all the way to the control terminals.
The connection cable must be screened and the
maximum length from the drive module to the
DC bar is limited to 25 m (82 ‘).
