Project Planning of Control Voltage (24V Supply)
6.1
General Information
To operate the drive system, supply the devices with control voltage. For the
project planning of the 24V supply of the drive system, take the requirements
of the devices used into account:
●
Voltage and voltage tolerances depending on line lengths and use of
holding brake.
See also
chapter 5.5 "Control Voltage (24V Supply) " on page 65
●
Power consumption of the drive controllers with control section and
power section
●
Power consumption of other components, e.g. holding brakes
●
Current carrying capacity of the connections for "looping through"
●
Buffering the control voltage supply might possibly be necessary
For the requirements of the supply units and converters, see Project
Planning Manual "Rexroth IndraDrive Supply Units and Power Sections" →
Chapter of the respective device → "Technical Data" → "Basic Data" → table
"Data for Control Voltage Supply".

Selecting the 24V Supply
6.2.1
General Information
The components need the 24V supply for correct operation. At components
of the Rexroth IndraDrive range, the external 24V supply takes place via the
connection X13 or via the connections 24V and 0V at the terminal block.
Via these connections, the components are supplied with 24V for
●
the power section of the drive controller or supply unit
●
brake control via X6
●
the control section of the drive controller
In particular, take mains failure situations into account and use
power supply units with buffer (UPS), if necessary.
The inputs/outputs of the I/O extensions MA1, MD1 and MD2 are
not supplied with voltage via the control section, but have their
own connections.
Take the additional power required for these connections into ac‐
count.
HCS02/HCS03 converters of the design "-N**V" have an integra‐
ted 24V supply. In applications without motor holding brake and
with CSB01.1N‑FC control section, they can be operated without
external 24V supply. Observe the notes on project planning for
the mains connection.
