Overtravel Signals
The overtravel signals include the P-OT (Forward Drive Prohibit) and the N-OT (Reverse Drive
Prohibit) signals.
You can operate the Servomotor in the opposite direction during overtravel by inputting a refer-
ence.
5.12.2
Setting to Enable/Disable Overtravel
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.

When the Servomotor stops due to overtravel during position control, the position deviation is
held.
You must input the CLR (Clear) signal to clear the position deviation.
Refer to the following section for information on the CLR signal.
