(2) Overtravel Function Setting
Parameters Pn50A and Pn50B can be set to specify either using or not using the overtravel function.
If the overtravel function is not used, forward and reverse operation will always be possible for the servomo-
tor, and no wiring for overtravel input signals will be required.

• A parameter can be used to re-allocate input connector number for the P-OT and N-OT signals. Refer to
3.3.1 Input Signal Allocations.
(3) Motor Stopping Method When Overtravel is Used
The stopping method when an overtravel (P-OT, N-OT) signal is input while the servomotor is operating can
be set with parameter Pn001.

• A servomotor under force control cannot be decelerated to a stop. The servomotor is stopped with the
dynamic braking (DB) or coasts to a stop according to the setting of Pn001.0. After the servomotor stops,
the servomotor will enter a coast state.
• For details on stopping methods when the servo turns OFF or when an alarm occurs, refer to 5.2.4 Stopping
Servomotors after /S_ON Turned OFF or Alarm Occurrence.
