( 2 ) Selecting Motor Stopping Methods for Overtravel
When using the overtravel function has been enabled, the following parameters are used to set the
methods for stopping the motor.
Select the methods for stopping when the P-OT or N-OT is input during motor running.
[ a ] Σ-II or Σ-III SERVOPACK
Select the stopping method and processing after stopping when an overtravel signal is input during
motor running.
Select the stopping method and processing after stopping when the Servo turns OFF.

Pn001.1 Overtravel Stop Mode
0
Stops the motor according to Pn001.0 setting (dynamic
brake or coasting) when overtravel is detected.
0
1
Decelerates the motor to a stop by applying the torque
specified in Pn406 (Emergency Stop Torque) when
overtravel is detected, and then sets it to zero clamp
(servolock) mode.
2
Decelerates the motor to a stop by applying the torque
specified in Pn406 (Emergency Stop Torque) when
overtravel is detected, and then sets it to coast (servo
OFF) mode.
