MC_ReadAxisError

In the case of an axis error the FB MC_ReadAxisError returns error code ‘40001’ (axis error occurred within motion controller) at its ‘ErrorID’ output. At output ‘AxisErrorID’ the error code of the motion controller is displayed. The associated motion controller error message texts are placed with text or XML files. All other error codes notifying internal FB-errors.

Descriptions of the values at outputs ‘ErrorID’ and ‘AxisErrorID’ you can find in [DIAG].
