Basic Functions That Require Setting before Operation
Note: 1. The setting of Pn00A is ignored if Pn00B is set to n.0 or n.1.
2. Refer to the following section for details on Pn406 (Emergency Stop Torque).
Stopping the Servomotor by Setting Emergency Stop Torque on page 5-37
3. Refer to the following section for details on Pn30A (Deceleration Time for Servo OFF and Forced Stops).
Stopping the Servomotor by Setting the Deceleration Time on page 5-38
Stopping the Servomotor by Setting Emergency Stop
Torqu e
To stop the Servomotor by setting emergency stop torque, set Pn406 (Emergency Stop
Torque).
If Pn00A = 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.
* Set a percentage of the motor rated torque.
