Extended measuring function (MEASA, MEAWA, MEAC) (option)

5.8
Function
Several probes and several measuring systems can be used for the axial measuring.
When MEASA, MEAWA is programmed, up to four measured values are acquired for the
programmed axis in each measuring run and stored in system variables in accordance with
the trigger event.
Continuous measuring operations can be executed with MEAC. In this case, the
measurement results are stored in FIFO variables. The maximum number of measured
values per measuring run is also 4 with MEAC:
• Under $AA_MM1 to 4[axes] in the machine coordinate system
• Under $AA_MM1 to 4[axes] in the workpiece coordinate system
Programming
MEASA and MEAWA act blockwise and can be programmed in a block. If MEASA/MEAWA is
programmed with MEAS/MEAW in the same block, an error message is output.
MEASA[axis]=(mode, TE1,..., TE 4)
or
MEAWA[axis]=(mode, TE1,..., TE 4)
or
MEAC[axis]=(mode, measurement memory,TE1,..., TE 4)
