Sinumerik Alarm 21700 Channel %1 block %3 axis %2 touch probe already deflected, edge polarity not possible
Parameters:
%1 = Channel number
%2 = Axis name, spindle number
%3 = Block number
Definitions:
The probe programmed under the keyword MEAS or MEAW is already deflected and has switched. For a further measuring operation, the probe signal must first be canceled (quiescent state of the probe). The axis display is of no significance at the present time but an axis-specific evaluation has been planned for later stages of development.
Reactions:
– 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)
Remedy:
Verify the start position of the measuring operation or check the probe signals. Are the cables and connectors in good order?
Program Continuation:
Clear alarm with the RESET key. Restart part program
