Requirements to the drive system:
●
DC bus choke: Per drive system, use one additional component
HLL01.1N for connection to the DC bus of the third-party supply unit.
●
DC bus current: Comply with maximum allowed DC bus current of
100 A.
●
Additional capacitances: Use at least 50 μFper kW of installed continu‐
ous power in the form of DC bus capacitor unit HLC01.
●
Leakage capacitance C
ab
: The leakage capacitance per drive system
(motors and motor cables) mustn't be more than a maximum of 500 nF.
●
Capacitances against housing C
Y
: Per drive system, the capacitance
against housing mustn't exceed 2 × 850 nF (850 nF at L+, 850 nF at L-)
and mustn't fall below 2 × 300 nF (300 nF at L+, 300 nF at L-).
●
Peak voltage: Limit voltage L+ against
and L- against
to a maxi‐
mum of 1 kV.
●
If the drive system can be disconnected from the third-party supply unit
in operation (e.g., in the case of overcurrent by fuses), use DC bus re‐
sistor unit HLB01 with W
max
≥ W
max_installiert
.
Notes on Commissioning
Supply units, converters, inverters and additional components of the Rexroth
IndraDrive product range have a module bus X1. Via the module bus, infor‐
mation on the status within the drive system is exchanged and the power
supply from the mains is influenced.
Supply units of other product ranges have no module bus. With the drive firm‐
ware as of version MPx‑04VRS, you can configure an inverter as module bus
master. Integrate the relay contact of the module bus master configured as
Bb contact in the control circuit of the power supply in such a way that the
circuit is interrupted when the relay contact opens.
For information on configuration and parameterization of the drive control‐
lers, see Functional Description of firmware, chapter "Power Supply" and the
pertinent parameters

General Information
The mains connection consists of:
●
Protection against overload (e.g., fuses for line protection)
When dimensioning the fuses in the supply feeder and in branch‐
es, make sure to provide protection against overcurrent and over‐
load in the case of error.
See
chapter 15.3.5 "Dimensioning the Line Cross Sections and

If necessary, an autotransformer or isolating transformer for voltage ad‐
justment
