NOTICE
Shortening the service life of motor brake
The motor brake is used for holding purpose only. Frequent emergency stops with the
motor brake will shorten its service life.
Unless absolutely necessary, do not apply the motor brake as an emergency stop or
deceleration mechanism.
Braking sequence
The operating principle of the holding brake is configured during motor selection for motors
with incremental encoders and configured automatically for motors with absolute encoders.
The start of the closing time for the brake depends on the expiration of the shorter of p1227
(zero speed detection monitoring time) and p1228 (pulse suppression delay time).
