3.      3. Click ‘Diagnose’ button or press function key F6 from the main screen

 



4.      4. On the pop up screen, check if the lights circled in red on the controller screen are turned on and solid. If not, check the power connection to the corresponding drives.

 

         All drives are marked with letters in the controller box so you can locate the corresponding servo drive and check the related power cord is connected properly.
