6.2 Overtravel
Overtravel forces the machine to stop when any moving part of the machine exceeds the range
of movement. With the MP3000, the process for stopping as a result of overtravel is achieved
through the use of SERVOPACK functions.
Set the required parameters and ensure that the overtravel input signals are connected cor-
rectly for overtravel. The required parameter settings and how to connect to a Σ-V or Σ-7 Servo
Drive are described below.
