„ Holding Brake Setting
Set the following parameters to adjust brake ON timing so the holding brake is applied when
the Servomotor stops.
Set the brake timing used when the servo is turned OFF by the SV_OFF command or when
an alarm occurs during Servomotor with brake operation.
Brake ON timing when the Servomotor stops must be adjusted properly because Servomotor
brakes are designed as holding brakes. Adjust the parameter settings while observing equip-
ment operation.
