Installing the 24V Supply
As a matter of principle, the 24V supply of the devices of the drive system
Rexroth IndraDrive has to be designed in star-shaped form, i.e. for each
group of drive controllers or third-party components it is necessary to run
separate supply lines. This, too, applies to multiple-line arrangement in the
case of supply from a supply unit, for example.
A
Device group, e.g. IndraDrive C
B
Device group, e.g. IndraDrive M
C
Third-party component (e.g. PLC, valve etc.)
1)
Connection to central ground point (e.g. earth-circuit connector)
Fig.6-2:
Installing the 24V Supply
If you use several power supply units for 24 V supply:
●
Interconnect reference conductors 0 V of the individual pow‐
er supply units with low impedance
●
The output voltages of the power supply units must be within
the allowed voltage range.
●
Switch the power supply units on and off synchronously.
Reduce load-dependent voltage drops by using lines with suffi‐
ciently dimensioned line cross sections.
Chronological Order of 24V Sup‐
ply and Mains Voltage
Before mains voltage or DC bus voltage is applied to the devices, they have
to be supplied by the 24V supply.
In this context, observe the chapter
9 Circuits for the Mains Connection, page
