9.2 Overtravel Function
This section explains the overtravel function.
9.2.1 Overview
The overtravel function forces the machine to stop when the moving part of the machine exceeds the
range of movement. With the MP2200/MP2300, processing for stopping as a result of overtravel is
achieved by using SERVOPACK functions.
The SERVOPACK connections and parameter setting depend on the model of SERVOPACK. The
connections and parameter settings are described in the following sections.
9.2.2 Overtravel Input Signal Connections
When using the overtravel function, correctly connect the input signals for the overtravel limit
