Installing the EX Controller. The emergency stop button that came with the controller works in reverse. Up stops the machine. Down enables the machine to run. How to reverse the functions where Up is machine runs and Down is machine stops? Thanks.
When it is up/out is it closed/connected?
The emergency stop system is a normally closed circuit and must be plugged in for the CNC controller to operate. It is recommended to keep it within easy reach during machine operation so it is quickly accessible if the machine needs to be emergency stopped.
Does Estop trigger if the switch is not plugged in?
Yes, when it is up the circuit is open. When it is down, the circuit is closed.
No, the Estop does not trigger when the switch is not plugged in.
Sounds like you may have inadvertently reversed the input for the E Stop. Did you go into the advanced settings or open the PLC diagnostic and perhaps flip it the wrong way?
That’s possible. How do I access the PLC diagnostic screen? Thanks.
Figured it out. Alt i brings up the PLC diagnostic screen. Yes, the E Stop was reversed. That fixed it. Thanks.
Glad you found it!
Be careful in that menu, you can really get things messed up ![]()
