M5: Measurement
8.4 Axial measurement
A distinction is made between three measuring methods:
● MEASA: Measurement with deletion of distance-to-go
Example:
N10 MEASA[X]=(1,1,-1) G01 X100 F100
Measuring in mode 1 with active measuring system. Trigger events are the rising and falling
edge of the first probe (1) on the travel path to X=100.
Note
MEASA cannot be programmed in synchronized actions.
● MEAWA: Measurement without deletion of distance-to-go
Example:
N20 MEAWA[X]=(1,-1,1,-2,2) G01 X100 F100
Measuring in mode 1 with active measuring system. Trigger events are the falling and rising
edge of the first probe (1) and of the second probe (2) on the travel path to X=100.
● MEAC (option): Continuous measurement without deletion of distance-to-go
Example:
N30 MEAC[X]=(1,1,-2,2) G01 X100 F100
Measuring in mode 1 with active measuring system. Save the measured values under the
first FIFO (1). Trigger events are the falling and rising edge of the second probe (2) on the
travel path to X=100.
The measuring job is aborted with RESET or when the program advances to a new block.
Note
MEASA and MEAWA can be programmed in a block. If MEASA/MEAWA are programmed in
the same block as MEAS/MEAW, an error message will be output.
