AX2xxx Drive - Status and Error Codes

At AX2xxx-B200 drives, the variables DriveError,DriveState and Status are added via Variable I/O Data.

At AX2xxx-B900 drives, the I/O variables DriveState2 and DriveState3 appear by default under "Inputs", but the DriveError variables are to be added manually. Please find additional info under: AX2xxx Drive Tab - Inputs.

These input variables can be used for diagnosis purposes (e.g. if they are linked to a TwinCAT PLC process image, they can be evaluated inside the TwinCAT PLC run-time system).

In any case, the error and warning codes are displayed on the 7-segment display of the AX2xxxx drive (see column: "AX2xxx Display").

The below error messages and warnings could appear:
