CAUTION!
Inadequate supply voltage to the motor holding brake can result in a haz-
ardous situation, leading to serious injury and death. The control of the mo-
tor holding brake is not safety-related.
Please consider the power loss due to cable runs and transition resistances!
Measure the voltage at the brake input!
Test the function of the brakes by releasing and applying the brake.
