Special Motion Commands
Measure in mode 1 with active
measuring system, store measured
values under $AC_FIFO1, wait for
measuring signal with falling edge from
probe 1 on travel path to X = 1000.
Terminate measurement when axis
position is reached.
Store number of accumulated measured
values in parameter R1.
Read measured values from $AC_FIFO1
and store.
Delete distance-to-go
