5.8 Extended measuring function (MEASA, MEAWA, MEAC) (option)
Special Motion Commands
;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.
;Save measured value of the
;measuring system 1 for rising edge.
;Save measured value of the
;measuring system 2 for rising edge.
;Save measured value of the
;measuring system 1 for falling edge.
;Save measured value of the
;measuring system 2 for falling edge.
;Measurement in mode 2 with active
;measuring system. Wait for measuring
;signal in the following order:
;Rising edge of probe 1,
;falling edge of probe 1,
;rising edge of probe 2,
;falling edge of probe 2,
;on travel path to X = 100.
;Preprocessing stop
;Check success of measurement
;with probe 1
;Store measured value acquired on
;first programmed trigger event
;(rising edge probe 1).
;Store measured value acquired on
;second programmed trigger event
;(rising edge probe 1).
;Check success of measurement
;with probe 2
;Store measured value acquired on
;third programmed trigger event
;(rising edge probe 2).
;Store measured value acquired on
;fourth programmed trigger event
;(rising edge probe 2).
