(a) Servo-on (SON
)
command (from controller) ON/OFF
Tb [ms] after the servo-on (SON
) 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.
