Brake ON timing when the Servomotor stops must be adjusted properly because Servomotor
brakes are designed as holding brakes. Adjust the user constant settings while observing equip-
ment 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.
