Display mode
The following parameter assignments for programming the mode of representation of
measurement results can also be made:
● Display based on mean radius
● Display based on programmed radius
● Scaling of the diagram axes
If the measuring time calculated exceeds the time range that can be displayed from the trace
buffers (maximum measuring time = position control cycle frequency * 2048), a coarser
sampling rate is used for recording (n * position control cycle frequency), so that a complete
circle can be displayed.
Start measurement
The operator must use an NC Start to start the part program in which the circular motion for
the selected axes is stored (AUTOMATIC or MDA operating mode).
The measuring function is started with the vertical softkey Start.
The sequence of operations (NC Start for part program and Start measurement) can be
chosen by the user according to the application.
When the circularity test is active for the specified axes, the message "active" appears in the
"Status" display field.
