4.8 Extended measuring function (MEASA, MEAWA, MEAC) (option)
Function
Several probes and several measuring systems can be used for the axial measuring.
The MEASA or MEAWA command can be used to acquire up to four measures values for the
respective programmed axis; these are then saved in system variables in accordance with the
trigger event.
Continuous measuring tasks can be executed with the MEAC command. In this case, the
measurement results are stored in FIFO variables. The maximum number of measured
values per measurement is also four with MEAC.
Reading measurement results
Measurement results are available in the following variables:
• $AA_MM1...4[<axis>]
Measurement results in the machine coordinate system
• $AA_MW1...4[<axis>]
Measurement results in the workpiece coordinate system
Syntax
MEASA[<axis>]=(<mode>,<TE1>,...,<TE4>)
MEAWA[<axis>]=(<mode>,<TE1>,...,<TE4>)
MEAC[<axis>]=(<mode>,<measurement memory>,<TE1>,...,<TE4>)
