Possible Causes |
Solutions |
|---|---|
|
The commutation offset has not been entered in the digital name plate or the value is not plausible. |
Exchange the motor. |
|
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. |
 | Please consider this note! It is not sufficient just to exchange the feedback system, because the commutation offset must be determined and entered in the factory. |
