Programming example
Measurement with delete distance-to-go in mode 1
a) with 1 measuring system
...
N100 MEASA[X] = (1,1,-1) G01 X100 F100
N110 STOPRE
N120 IF $AC_MEA[1] == FALSE gotof END
N130 R10 = $AA_MM1[X]
N140 R11 = $AA_MM2[X]
N150 END:
Programming example
b) with 2 measuring systems
...
N200 MEASA[X] = (31,1-1) G01 X100 F100
N210 STOPRE

Special Motion Commands
Measurement in mode 1 with active
measuring system. Wait for measuring
signal with rising/falling edge from probe
1 on travel path to X = 100.
Preprocessing stop
Check success of measurement.
Store measured value acquired on first
programmed trigger event (rising edge)
Store measured value acquired on second
programmed trigger event (falling edge)
Measurement in mode 1 with both
measuring systems. Wait for measuring
signal with rising/falling edge from probe
1 on travel path to X = 100.
Preprocessing stop
Check success of measurement.
Store measured value of measuring
system 1 on rising edge
Store measured value of measuring
system 2 on rising edge
Store measured value of measuring
system 1 on falling edge
Store measured value of measuring
system 2 on falling edge
