Brake ON Timing
If the equipment moves slightly due to gravity when the brake is applied, set the fol-
lowing parameter to adjust brake ON timing.
Parameter
Brake Reference Servo OFF
Pn506
Delay Time
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 opera-
tion) is active. The equipment may move slightly due to gravity depending on
equipment configuration and brake characteristics. If this happens, use this parame-
ter 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 grav-
ity in the time it takes for the brake to operate.
