Project planning of control voltage

Control voltage for drive systems

Sizing the control voltage supply

Drive controller power require‐
Some components of a drive system have to be supplied with control voltage.
When doing the project planning for control voltage supply, include the drive
system component requirements:
● Depending on the motor cable length and whether or not motor holding
brakes are used, the permitted tolerances of the supply voltage
● Power consumption of the drive controllers
● Power consumption of other loads (e.g., motor holding brakes, digital
outputs)
● Current carrying capacity of the connection point for control voltage sup‐
ply on the component for the purpose of looping through the control volt‐
age to other components
PELV
For the 24V supply of the devices of the Rexroth IndraDrive Cs
range, use a power supply unit or a control-power transformer
with protection by PELV according to IEC 60204-1 (section 6.4).
In the scope of CSA/UL, the data of the control-power transformer
are limited to:
● Max. output voltage: 42.4 V
●

Determining the power requirements

The total power requirements of the control voltage supply of a drive control‐
ments
ler result from the sum of the following power values:
● Basic device (drive controller without connected encoders)
● Optional connection interfaces (e.g., communication, additional encoder
evaluation)
● Connected encoder systems
● External loads
For the configuration of your drive controller, see the
code.
