Notes on setting the release (opening) time (p1216):
● The release time (p1216) should be set longer than the actual release time of the holding
brake. As a result, the drive will not accelerate when the brake is closed.
Notes on setting the closing time (p1217):
● The closing time (p1217) should be set longer than the actual closing time of the holding
brake. As a result, the pulses are suppressed only after the holding brake is closed.
● If the closing time (p1217) is set too low compared to the actual closing time of the
holding brake, the load may drop suddenly.
● If the closing time (p1217) is set too high compared to the actual closing time of the
holding brake, the controller acts against the holding brake and thus reduces its service
life.
