(b) Pn506 (Brake ON Timing after Motor Stops)
Adjust brake timing with the following parameter if the machine moves slight due to gravity or other factors.
Pn506
When using a servomotor with a brake, set the timing of turning OFF the Servo (i.e., stopping the motor out-
put) in reference to the output signal that controls the brake (/BK).
This parameter is used to set the timing when the motor is stopped. Brake operation while the motor is running is set in
INFO
Pn507 and Pn508.
For the standard settings, the Servo will turn OFF simultaneously with the /BK output (Brake Operation). If gravity will
cause the machine to move slightly at this time due to machine configuration or brake characteristics, turning OFF the
Servo can be delayed to make sure there is no movement.
(c) Pn507 and Pn508 (Brake ON Timing When Motor Running)
Adjust the timing of the holding brake when the motor is running with the following parameters so that the
brake is applied after the servomotor stops.
Pn507
Pn508
When using a servomotor with a brake, set the timing of applying the brake when the Servo turns OFF during
motor running due to an /S-ON input signal or alarm.
The brake on the servomotor is designed as a holding brake and it must be applied only after the motor has stopped. Adjust

this parameter while observing machine operation.
