Sinumerik Alarm 21700 Channel %1 block %3 axis %2 touch probe already deflected, edge polarity not possible
%1 = Channel number
%2 = Axis name, spindle number
%3 = Block number
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.
