Components marked with gray background color: Optional, de‐
pending on the application; the choke is used to reduce current
harmonics
A
Component HCS01 (more powerful than component B); con‐
nected to other components via DC bus
B
Component HCS01 (less powerful than component A); connec‐
ted to other components via DC bus
Bb
Bb relay contact wiring
M
Module bus

Parallel operation
Connect the Bb relay contacts of all supplying components in ser‐
ies. You thereby ensure that the mains contactor is switched off in
case there is an error in a component.

Calculating the mains-side phase current
The mains-side phase current is required for the following cases:
●
Selecting mains contactor
●
Determining fuses in the mains connection
●
Determining line cross section
●
Selecting other components in the mains connection (mains filter, mains
choke)
Operation under rated conditions
For data on mains contactor, fuses and cross section in operation under rat‐
ed conditions, see technical data of the respective component.
Operation at partial load
Operation at partial load can lead to smaller mains contactors, fuses and line
cross sections.
If defined data for operation at partial load are available, the mains-side
phase current can be determined as follows:
1.
Determine motor power
Take power of drive controller-motor combination from Rexroth Indra‐
Size or calculate it.
