You can use Pn50A = n.X
(P-OT (Forward Drive Prohibit) Signal Allocation) and Pn50B =
n.
X (N-OT (Reverse Drive Prohibit) Signal Allocation) to enable and disable the overtravel
function.
You do not need to wire the overtravel input signals if you are not going to use the overtravel
function.
You can allocate the P-OT and N-OT signals to other connector pins. Refer to the following
section for details.

Motor Stopping Method for Overtravel
You can set the stopping method of the Servomotor when overtravel occurs in Pn001 =
n.
XX (Servo OFF or Alarm Group 1 Stopping Method and Overtravel Stopping Method).
*
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)), and then the Servomotor will enter a coasting state.
Refer to the following section for information on stopping methods other than those for over-
