Looping Through the Control Voltage Supply
Property damage in case of error caused by
too small line cross section!
NOTICE
Make use of the contact bars provided to loop-through and observe the cur‐
rent carrying capacity of the connections for 24V supply at the devices used
(see Project Planning Manual "Rexroth IndraDrive Supply Units and Power
Sections" → "Terminal Block, 24 - 0V (24V Supply)" and "X13, Control Volt‐
age").
At the drive controllers, the 24V supply is looped through via contact bars
from one device to the next (for HCS02, HLB01.1C and HLC01.1C via lines
at X13).

The result I

must be smaller than the specified current carrying capacity of
the connection point.
Looping through at HCS02
The current carrying capacity of X13 at HCS02 is only suited for
looping through low currents. Limit the looping through to loads
with low power consumption, such as HCS02.1E-W0012 with
CSB01.1N-FC and additional components HLB01.1C.
Inrush current I
EIN
When connecting the control voltage source to the connection
point for 24V supply, a higher inrush current I
EIN
will flow for the
specified duration t
EIN3Lade
.
The inrush current is increased with every additional drive control‐
ler.
