14.2 Overtravel Function
This section explains the overtravel function.
14.2.1 Overview
The overtravel function forces the machine to stop when the moving part of the machine exceeds the range of
movement. With the MP2100/MP2100M, 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.
14.2.2 Overtravel Input Signal Connections
