11.2 Overtravel Function
The overtravel function forces the machine to stop when the moving part of the machine exceeds the range of move-
ment. With the MP2000-series Machine Controller, 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.
