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.
The following parameters must be set to ensure the overtravel input signals are connected correctly
for the overtravel function.
Correctly connect the input signals for the overtravel limit switches shown below to the correspond-
ing pins on the SERVOPACK CN1 or 1CN connector.
