(a) Servo-on signal (SON) ON/OFF
Tb (ms) after the servo-on (SON) signal is switched off, the 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. Therefore, when
using the electromagnetic brake in a vertical lift application or the like, set
Tb to about the same as the electromagnetic brake operation delay time to
prevent a drop.
