Sinumerik Alarm 10756 Channel %1 block %2 deselection of the tool radius compensation via KONT not possible at the programmed end point

Sinumerik Alarm 10756 Channel %1 block %2 deselection of the tool radius compensation via KONT not possible at the programmed end point

Parameters:
%1 = Channel number
%2 = Block number, label

Definitions:
On deselection of the cutter radius compensation, the programmed end point is within the compensation circle. If this point were in fact to be approached without compensation, there would be a contour violation.
If the cutter radius compensation is deselected via G40, the approach behavior (NORM or KONT) determines the compensation movement if the programmed end point is behind the contour. With KONT, a circle is drawn with the cutter radius about the last point at which the compensation is still active. The tangent passing through the programmed end position and not violating the contour is the retraction movement.
If the start point is within the compensation circle around the target point, no tangent passes through this point.

Reactions:
– Local alarm reaction.
– Alarm display.
– Interface signals are set.
– Correction block is reorganized.
– NC Stop on alarm at block end.

Remedy:
Place deselection of the CRC such that the programmed end point comes to rest outside the compensation circle around the last active compensation point. The following possibilities are available:
• Deselection in the next block
• Insert intermediate block
• Select retract behavior NORM

Program Continuation:
Clear alarm with NC START or RESET key and continue the program.
