6.3.4 Electromagnetic Brake output
(a) Servo on signal 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 Tb to the time which is about equal to
the electromagnetic brake operation delay time and during which the load will not drop.
