„ 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 input signal /S-ON (CN1-40) 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.
/BK Signal Output Conditions During Servomotor Operation
The circuit is open under either of the following conditions:
The actual setting will be the maximum speed even if Pn507 is set higher than the maximum
speed.
