7.7 Simulated measuring
Figure 7-25
The measured value is the actual value of the axis at the instant in time that the switching
signal programmed in the measuring block occurs (rising / falling edge).
If several axes are programmed in a measuring block, then a dedicated switching position is
obtained for each axis by the position offset that is axially taken into consideration. The
probe signal is generated at the first axial switching position that is reached.
Note
Probe signals
The probe signals are always simultaneously generated for probes 1 and 2.
Negative offset values
The switching position is shifted behind the end position by entering a negative value for the
position offset. In this case, no probe signals are generated.
Examples
The position offset is set to 0.1 mm: MD13231 $MN_MEAS_PROBE_OFFSET = 0.1
