Cause : Encoder data serial protocol comes when connection fault of the serial protocol on multiturn encoders (SSI/Endat).

  1. Serial protocol is defective on multiturn encoders. See F051 for causes/counter- measures.
  2. As a general rule, it is necessary to initialize the starting position again => power OFF/ON or switch to the drive settings and back again!!!
