Circuits for Mains Connection of Rexroth IndraDrive C Drive
Controllers
9.3.1
General Information
The mains contactor connected in the incoming circuit controls the energy
flow to the drive controller. This allows separation from the mains in the case
of error. The Bb contact at the control section of the drive controller or the Bb
contact of the mains supply decisively influences the circuit.
Circuits HCS02
For HCS02 drive controllers, the following circuits for the mains connection
are described:
●
Control of external mains contactor
●
Control of external mains contactor for devices with integrated control
voltage supply
●
Control of external mains contactor with DC bus resistor unit HLB01.1C
Circuits HCS03
For HCS03 drive controllers, the following circuits for the mains connection
are described:
Control of external mains contactor
Configuration "Rel 1" as Bb Con‐
tact
Power voltage is only switched to drive system, when the closing of the Bb
contact signals readiness for power voltage on.
For this purpose, there is the isolated contact "Rel 1" at the control sections.
The behavior of this contact can be configured via the parameter "P-0-0860,
Converter configuration":
●
Behaves as converter, if drive controller is to get supply voltage via
mains connection (e.g., for type of mains connection "individual supply"
or "central supply")
●
Behaves as inverter, if drive controller is to get supply voltage via con‐
nection DC bus (L+, L-) (e.g., for type of mains connection "central sup‐
ply" as supplied device)
Include the converter contacts in the circuit in such a way that they make the
mains contactor drop out in the case of error (when the contact opens).
You can assign other information to the "Rel 1" contacts of the drive control‐
lers configured as inverters. Via this contact you can, for example, control a
second holding brake by entering a signal from "S-0-0398, IDN list of configu‐
rable data in signal status word" in parameter "P-0-0300, Digital I/Os, assign‐
ment list".

Control of External Mains Contactor for HCS02 and HCS03
General Information
Risk of damage!
NOTICE
Before switching the drive controller on again, wait at least for 300 ms plus
the switch-off delay of the mains contactor.
