(a)Servo-on (SON) command (from controller) ON/OFF

Tb (ms) after servo-on (SON) is switched off, servo lock is released and the servo motor coasts. If the electromagnetic brake is made valid in the servo lock status, the brake life may be shorter. For use in vertical lift and similar applications, therefore, set delay time (Tb) to the time which is about equal to the electromagnetic brake operation delay time and during which the load will not drop.
