9.3 Drive functions

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
