Axis %1 drive %2 direct feedback recognized
Parameters:
%1 = NC axis number
%2 = Drive number
Definitions:
The current rotor position and the position information read out by the encoder on ramp-up were
compared with each other and a deviation of more than 45 degrees was found.
Reaction:
NC not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.

Remedy:
- The deviation points to a local contamination of the encoder or an erroneous or loose encoder
assembly. The encoder must be examined accordingly.
Operation may commence again only after successful error correction as there is a risk of
uncontrollable movements!
- NCK reset
Program
Continuation:
Switch control OFF - ON.
