SINUMERIK 808D ADVANCED alarms
3.2 NCK alarms
Definitions: 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).
Reaction: Local alarm reaction.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Correct the measurement tasks.
Program Clear alarm with the RESET key. Restart part program
Continuation:
21702 [Channel %1: ] Block %3 axis %2 measurement canceled
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Block number
Definitions: 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 axes are not identical.
When making measurements without handshake, two probes must be available in drive parameters p0680 index 0
and 1.
Reaction: Alarm display.
Remedy: Check the traversing movement in the measurement 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?
- Is the probe correctly wired and configured on the hardware side (e.g. drive parameters p0488 and p0489)?
Either program all GEO axes explicitly or program the traversing movement with the POS[axis] command.
Program Clear alarm with the Delete key or NC START.
Continuation:
21703 [Channel %1: ] Block %3 axis %2 touch probe not deflected, illegal edge polarity
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Block number
Definitions: The selected probe is not (!) deflected and therefore cannot record any measured value from the deflected to the non-
deflected state.
Measurement level 2 (MEAWA, MEASA, MEAC)
The degree of deflection of the probe at the start of the measurement task is identical to the first programmed
measurement signal edge. The test is only performed in mode 2.
Reaction: Local alarm reaction.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
