Fault-Codes
If the controller detects an error, the controller continues to work with restrictions or stops operation
depending on the error. Depending on how serious the error is, the drive current will be reduced
(machine moves very slowly) or the controller will shut off completely.
The following table describes the error codes and how to correct them.
Note: The Error / Error Action column contains both the error name and the action (s) of the controller
when the error is detected.
