代码 10912: [Channel %1: ] Block %2 preprocessing and main run might not be synchronized

Parameters: %1 = Channel number %2 = Block number, label Definitions: The preset positioning axis run cannot be accura tely calculated beforehand. The reason for this is either that the axes involved in the transformation are traversed as positioning axes or that a transformation pole is circumnavigated too frequently by the curve. The velocity check is performed starting from this bl ock in the main run. It is more conservative than with anticipated calculation. The Look Ahead function is deactivated. If it is not possible to take over the velocity check into the main ru n, part program processing is aborted. Reaction: Alarm display. Remedy: No action is usually necessary. The velocity control operates more effectively, however, if the part program is modified. - If a transformation pole is circumnavigated several ti mes by the curve, it helps to split up the block into smaller parts. - If a positioning axis is the caus e, you should check whet her the axis can be traversed as a path axis. The Look Ahead function remains deactivated until preprocessing can be bas ed on defined conditions again (e.g. as a result of change from JOG->AUTO, tool or tool edge change). Program Continuation: Clear alarm with the Delete key or NC START. Diagnostics Manual (DAsl), 03/2009
