SERCOS drive shall be moved, but communication phase is less than 4.
Description | The SERCOS drive is to be moved although the communication phase is less than four. Possible causes:

- A manual phase switch was executed
- Short interruption of the data transmission e.g. kink in the optical fibre
- A drive error e.g. no supply voltage

Possible solutions:

Wait until communication phase 4 is reached.
