Rexroth IndraDrive Control Circuits for the Mains Connection 11-3
DOK-INDRV*-SYSTEM*****-PR02-EN-P
11.2 Control Circuits for Mains Connection of Drive
Controllers Rexroth IndraDrive C
The mains contactor connected in the incoming circuit controls the energy
flow to the drive controller allowing separation from the mains in the case
of error. The control circuit is decisively influenced by the Bb contact at
the control section of the drive controller or the Bb contact of the mains
supply.
Power voltage only switched to drive system after Bb contact signals
readiness for power voltage on by its closed status.
Control via External Mains Contactor - HCS02 and HCS03
CAUTION
Damage to the device!
⇒
Before switching the drive controller on again, wait at
least for 300 ms plus the switch-off delay of the
mains contactor.
Standard Design for HCS02 and HCS03 Drive Controllers
