Further information
Diameter values (DIAMON/DIAM90)
The diameter values apply for the following data:
• Actual value display of the transverse axis in the workpiece coordinate system
• JOG mode: Increments for incremental dimensions and handwheel travel
• Programming of end positions:
Interpolation parameters I, J, K for G2/G3, if these have been programmed absolutely with
AC.
If I, J, K are programmed incrementally (IC), the radius is always calculated.
• Reading actual values in the workpiece coordinate system for:
MEAS, MEAW, $P_EP[X], $AA_IW[X]
