10.2 Overtravel Function
The overtravel function forces the machine to stop when the moving part of the machine exceeds the
range of movement. With the 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.
