Voltage connection for brake
Note: The motor holding brake is not supplied by the drive controller.
Observe the data of the motor holding brake.
Note: It is impossible to loop through the voltages to other drive
controllers. Other drive controllers have to be connected to the
voltage source in star-shaped form.
Risk of damage!
