CNC controller Only Jog mode works

Turn on the CNC controller, it is working only under Jog mode, other modes like MDI, AUTO, EDIT and all other modes could not be entered.

And the CNC controller only enter the JOG mode after turn on it, and the JOG functions are working.

Check below:

1-      Is there any key or keyboard short circuits?

2-      Check the CNC PLC ladder and see if there is any mistake?

Then we found the keyboard has problem, change it then the CNC controller and machine resume.
