Brake ON Timing
If the equipment moves slightly due to gravity when the brake is applied, set the
following parameter to adjust brake ON timing.
This parameter is used to set the output time from the brake control signal /BK until
the servo OFF operation (servomotor output stop) when a servomotor with a brake is
used.
With the standard setting, the servo is turned OFF when the /BK signal (brake
operation) is active. The equipment may move slightly due to gravity depending on
equipment configuration and brake characteristics. If this happens, use this
parameter to delay servo OFF timing.
This setting sets the brake ON timing when the servomotor is stopped. Use Pn507
and 508 for brake ON timing during operation.
Note: The servomotor will turn OFF immediately if an alarm occurs. The equipment may move due to
gravity in the time it takes for the brake to operate.
