With the factory setting, the /BK signal is output at the same time as the servo is turned OFF. The servo
OFF timing can be changed with a parameter.

This output signal controls the brake and is used only for a servomotor with a brake. This output signal
is not used with the factory setting.The output signal must be allocated with Pn511. It does not need to
be connected for servomotor without a brake.

· When using the servomotor to control a vertical axis, the machine movable part may shift slightly
depending on the brake ON timing due to gravity or an external force. By using this parameter to delay
turning the servo OFF, this slight shift can be eliminated.
· This parameter changes the brake ON timing while the servomotor is stopped.
For details on brake operation while the servomotor is operating, refer to

■Important
The servomotor will turn OFF immediately when an alarm occurs, regardless of the setting of this
parameter. The machine movable part may shift due to gravity or external force during the time until the
brake operates.
