7.12 Technical Data Brakes
FAILSAFE, HOLDING BRAKE
The holding brake is designed to provide static holding torque to the motor shaft with the brake coil de-energized.
The brake must first be released (coil energized) prior to commanding motor rotation as determined by its drop-
out time. The brake is intended for holding or "parking" of a stationary motor. It is not intended for dynamic brak-
ing. There should be absolutely no motion of the rotor when power is removed from the brake coil.
It may be used for a limited number of emergency stop conditions, however such use will eventually cause wear,
leading to eventual malfunction of the brake. Number of emergency stops strongly depends on applied load.
Contact Kollmorgen for proper calculation of energy That needs to be absorbed during emergency stops in applic-
ation.
Contamination of the motor internal compartment by oil or other foreign materials will result in failure of the brake.
Check the suitability of motor sealing for the working environment.
