Mounting accessories
To protect the end positions against uncontrolled excess travel:
Check the necessity of proximity sensors (hardware limit switches).
If proximity sensors are used as limit switches:
Preferably use proximity sensors with normally closed function.
This protects against excess travel beyond the end position if the proximity sensor cable is broken.
If proximity switches are used as reference switches:
Use proximity sensors that correspond to the input of the controller being used.
For inductive proximity sensors: Use switch lug
