● Part program programming:
– End positions, independent of reference mode (G90 / G91)
– Interpolation parameters of circular-path programming (G2 / G3) if these are
● Actual values read with reference to the workpiece coordinate system (WCS):
– $AA_MW[<transverse axis>]
– $P_EP[<transverse axis>]
– $AA_IW[<transverse axis>]
DIAM90/DIAM90A[<Axis>]
After activation of the reference-mode-dependent diameter programming with DIAM90/
DIAM90A[<Axis>], the following data are always displayed in relation to diameter regardless
of the operating mode (G90 / G91):
● Actual value
● Actual values read with reference to the workpiece coordinate system (WCS):
– $AA_MW[<transverse axis>]
– $P_EP[<transverse axis>]
– $AA_IW[<transverse axis>]
DIAMCYCOF/DIACYCOFA[<Axis>]
With DIAMCYCOF / DIACYCOFA[<Axis>], a changeover to radius programming takes place
within the controller. The diameter programming status that was active before DIAMCYCOF or
DIACYCOFA[AX] continues to be displayed to the HMI.
Permanently radius-related data
For transverse axes, the following data is always entered, programmed and displayed in
relation to radius:
● Part program programming
– Interpolation parameters of circular-path programming with CIP
● Offsets:
– Tool offsets
– Programmable and configurable frames
– External work offset
– DRF and preset offset
– etc.
