11-4 Control Circuits for the Mains Connection Rexroth IndraDrive
DOK-INDRV*-SYSTEM*****-PR02-EN-P
Design for HCS02 and HCS03 Drive Controllers with
Integrated 24V Control Voltage Supply
Drive controllers with integrated 24V control voltage supply are used, for
example, to maintain signal processing for controlled return motion in
case the external 24V control voltage supply fails.
Note: The integrated 24V control voltage supply cannot be used for
motor brake supply.
To supply the motor brakes use an external 24V supply.
Note: In the case of devices with integrated 24V power supply
(HCS02.1E-....-NNNV), the drive controller has to be supplied
with external control voltage before the mains voltage is
switched on.
Exception: Drive controllers HCS02.1E-...-NNNV with control
sections CSB01.1N-FU.
Design for HCS02 and HCS03 Drive Controllers with
Integrated 24V Control Voltage Supply and CSB01.1N-FU
Control Sections
When using the drive controllers HCS02.1E-...-NNNV and HCS03.1E-...-
NNNV with control sections CSB01.1N-FU it is possible to do without the
external 24V control voltage supply.
