Control voltage
Control voltage for drive systems
Some components of a drive system have to be supplied with control voltage.
When selecting a control voltage supply, observe the requirements of the com-
ponents in the drive system:
● depending on the motor cable length and the use of motor holding brakes
● Power consumption of the drive controllers
● Power consumption of further consumers (e.g., motor holding brakes, digital
● Current carrying capacity of connection point for control voltage supply at
Control voltage supply
Determining the power requirement
Power requirement of the drive controller
The total power requirement of the control voltage supply of a drive controller
results from the sum of the following power values:
● Basic device (drive controller without connected encoders)
● Optional connection interfaces (e.g. communication, additional encoder
● Connected encoder systems
● External loads
For the configuration of your drive controller, see the nameplate and the type
code.
The tables below contain the individual power values required by the drive con-
troller. The power requirement of the supplying 24V power supply unit results
from the sum of these individual power values.
