(1) Servo-on command (from controller) ON/OFF
Tb [ms] after the servo-on 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 delay time (Tb) to about the same
as the electromagnetic brake operation delay time to prevent a drop.
