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
machine operation.
/BK Signal Output Conditions During Servomotor Operation
The circuit is open under either of the following conditions:
1
Motor speed drops below the setting at Pn507 after Servo OFF.
2
The time set at Pn508 has elapsed since Servo OFF.
The actual setting will be the maximum speed even if Pn507 is set higher than the maximum
speed.
