Sinumerik Alarm 14403 Channel %1 block %2 preprocessing and main run might not be synchronized
%1 = Channel number

Positioning axis runs cannot be accurately calculated beforehand. Consequently, the position in the MCS is not known exactly. It might therefore be possible that a change in the multiple significance of the transformation has been performed in the main run although no provision was made for this in the preprocessing run.
