Sinumerik Alarm 21702 Channel %1 block %3 axis %2 measurement aborted
%1 = Channel number
%2 = Axis name, spindle number
%3 = Block number
The measurement block has ended (the programmed end position of the axis has been reached) but the activated touch probe has not yet responded. Measurement level 2 (MEAWA, MEASA, MEAC) Measured values cannot be converted to the workpiece coordinate system. The measured values of the GEO axes programmed in the measurement task are only available in the machine coordinate system. Causes: Not all GEO axes were programmed in the measurement task. At least one measured value is therefore missing for conversion back into the workpiece coordinate system.
Further causes: The measurement tasks programmed for all GEO axis are not identical.
– Alarm display.
Verify the traversing movement in the measurements block.
• Is it necessary in all cases for the activated probe to have switched up to the specified axis position?
• Are the probe, cable, cable distributor, terminal connections in good order? Either program all GEO axes explicitly or program the traversing movement with the POS[axis] command.
Clear alarm with the Delete key or NC START.
