Solutions

Check the parametrization of the resolution in the IDN P-0-0150 or P-0-0180.

Change the parametrization if necessary.

An unknown hard- or software error has occurred.

Disconnect the servo drive from the mains (including the 24 V power supply) and start a new attempt. If this error occurs repeatedly, please call the Beckhoff branch office that is responsible for you.

Defective feedback system, parametrized internal resolution is too high.

Exchange the feedback system.

Please consider this note!

The AX5000 supports a max. position value resolution of 12 bits (EnDat) with "multi-turn".
