REXROTH IndraDrive C Series User Manual

Rexroth IndraDrive C Electrical Data 6-19
DOK-INDRV*-HCS02.1****-PR02-EN-P
Devices with Internal Control Voltage Supply Generation from DC bus
(HCS02.1E-W00xx-NNNV)
The internally generated control voltage is used for stand-alone supply of
the drive controller or buffering in case the external 24V supply fails. It is
not used for supplying motor holding brakes.

Fig. 6-19: Control voltage -***V
Note: Overvoltages of more than 33 V have to be derived by
measures in the electrical equipment of the machine or
installation. This includes:
• 24-Volt mains sections that reduce incoming overvoltages
to the allowed value.
• Overvoltage limiters at the control cabinet input that limit
existing overvoltages to the allowed value. This also
applies to long 24-Volt lines that have been laid in parallel
with power and mains cables and can absorb overvoltages
caused by inductive or capacitive coupling.
