Further information
Diameter values (DIAMONA/DIAM90A)
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 manual 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]
Non-modal axis-specific diameter programming (DAC, DIC, RAC, RIC)
The statements DAC, DIC, RAC, RIC are permissible for any commands for which channel-
specific diameter programming is relevant:
● Axis position: X..., POS, POSA
● Oscillation: OSP1, OSP2, OSS, OSE, POSP
● Interpolation parameters: I, J, K
● Contour definition: Straight line with angle specification
● Rapid retraction: POLF[AX]
● Traversing in the tool direction: MOVT
● Smooth approach and retraction:
G140 to G143, G147, G148, G247, G248, G347, G348, G340, G341
