6.2.2 Setting the Overtravel Limit Function
The overtravel limit function forces movable machine parts to stop if they exceed the allow-
able range of motion.
The forward/reverse run prohibited function uses software to stop the SERVOPACK. This method
may not satisfy the standards, depending on the safety specifications for the application. If necessary,
add an external safety circuit.
 Using the Overtravel Function
To use the overtravel function, connect the overtravel limit switch input signal terminals
shown below to the correct pins of the SERVOPACK CN1 connector.
Connect limit switches as shown below to prevent damage to the machines during linear
motion.
