Reading measurement results
The measured values of the axes acquired by probes can be read through the following system
variables in the part program and in synchronized actions.
System variable Meaning
$AA_MM[<Axis>] Probe measured value in the machine coordinate system
$AA_MW[<Axis>] Probe measured value in the workpiece coordinate system
3.7.8 Axis-specific measurement (MEASA, MEAWA, MEAC) (option)
With axis-specific measuring, activation can take place in the part program or in synchronized
actions. If two measuring systems are available for the axis, both can be used for the
measurement.
The following measuring methods are available:
● Measurement with delete distance-to-go (MEASA)
● Measurement without delete distance-to-go (MEAWA)
● Continuous measurement without delete distance-to-go (MEAC)
With MEASA or MEAWA for the programmed axis, up to four measured values are acquired for
each measurement and are then saved in system variables in accordance with the trigger
event.
With continuous measurement with MEAC, the measurement results are stored in FIFO
variables.
Syntax
MEASA[<Axis>]=(<Mode>,<TE1>,...,<TE4>)
MEAWA[<Axis>]=(<Mode>,<TE1>,...,<TE4>)
MEAC[<Axis>]=(<Mode>,<MeasMem>,<TE1>,...,<TE4>)
Note
MEASA and MEAWA are non-modal; and can be programmed together in one block. If, on the
contrary, MEASA/MEAWA are programmed with MEAS/MEAW in one block, there is an error
message.
Meaning
MEASA: Axis-specific measurement with deletion of distance-to-go
Effectiveness: Non-modal
MEAWA: Axes-specific measurement without delete distance-to-go
Effectiveness: Non-modal
MEAC: Axis-specific, continuous measurement without delete distance-to-go
Effectiveness: Non-modal
