Stopping Method Selection for Forced Stops

Use Pn00A = n.X (Stopping Method for Forced Stops) to set the stopping method for
forced stops.
Pn00A
Note: You cannot decelerate a Servomotor to a stop during torque control. For torque control, the Servomotor will
be stopped with the dynamic braking or coast to a stop according to the setting of Pn001 = n.X (Servo
OFF or Alarm Group 1 Stopping Method).
Stopping the Servomotor by Setting Emergency Stop
Torque (Pn406)
To stop the Servomotor by setting emergency stop torque, set Pn406 (Emergency Stop
Torque).
If Pn001 = n.X is set to 1 or 2, the Servomotor will be decelerated to a stop using the
torque set in Pn406 as the maximum torque.
The default setting is 800%. This setting is large enough to allow you to operate the Servomo-
tor at the maximum torque. However, the maximum emergency stop torque that you can actu-
ally use is the maximum torque of the Servomotor.
Pn406
Set a percentage of the motor rated torque.

Stopping the Servomotor by Setting the Deceleration Time
for Servo OFF and Forced Stops (Pn30A)
To specify the Servomotor deceleration time and use it to stop the Servomotor, set Pn30A
(Deceleration Time for Servo OFF and Forced Stops).
Pn30A
If you set Pn30A to 0, the Servomotor will be stopped with a zero speed.
The deceleration time that you set in Pn30A is the time to decelerate the motor from the maxi-
mum motor speed.
