6.11 Overtravel and Related Settings
6.11.1 Overview
Overtravel is a function of the SERVOPACK that forces the Servomotor to stop in
response to a signal input from a limit switch that is activated when a moving part of the
machine exceeds the safe range of movement.
The overtravel signals include the P-OT (Forward Drive Prohibit) and the N-OT (Reverse
Drive Prohibit) signals.
You use the P-OT and N-OT signals to stop the machine by installing limit switches at the
positions where you want to stop the machine that is operated by the Servomotor.
A SERVOPACK wiring example is provided below.

Using the overtravel function is not necessary for rotating applications such as rotary
tables and conveyors. No wiring for overtravel input signals is required.
This section describes the parameters settings related to overtravel.
