Channel %1 block %3 axis %2 measurement not possible
%1 = Channel number
%2 = Axis name, spindle number
%3 = Block number
Measurement level 2 (MEASA, MEAWA, MEAC).
There is an error in the programmed measurement task.
Possible causes:
• Invalid measurement mode
• Invalid probe
• Invalid encoder
• Invalid number of measurement signal edges
• Identical measurement signal edges are only programmable in mode 2
• Invalid FIFO number
• Mismatch between the number of FIFOs programmed and the number of probes used
in the measurement task.
Further causes:
• A measurement task is already active (e.g. from a synchronized action).
- Alarm display.
- Interface signals are set.
- Local alarm reaction.
- NC Stop on alarm.
- NC Start disable in this channel.
- If the axis is a single axis when this alarm is triggered, the alarm is only effective for this
axis (not effective for e.g. the channel or mode group)
Correct the measurement tasks.
Clear alarm with the RESET key. Restart part program
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 mea-
sured 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.
