P1: Transverse axes
4.1 Function
Programming:
Acceptance during axis re‐
placement:
Axis-specific non-modal dia‐
metral/radius programming:
DIAM*: DIAMOF, DIAMON, DIAM90, DIAMCYCOF
DIAM*A[<Axis>]: DIAMOFA[<Axis>], DIAMONA[<Axis>], DIAM90A[<Axis>], DIACYCOFA[<Axis>], DIAMCHANA[<Axis>]
<Axis>: Axis name for geometry, channel or machine axis name
Note
Rotary axes are not permitted to serve as transverse axes.
Diameter-related data
DIAMON/DIAMONA[<Axis>]
After activation of the diameter programming with DIAMON/DIAMONA[<Axis>] (see
"Programming (Page 121)"), the following data refer to diameter dimensions:
● Display data of transverse axis in the workpiece coordinate system:
– Setpoint and actual position
– Distance-to-go
– REPOS offset
● "JOG" mode:
– Increment (INC) through incremental manual handwheel traversing (depending on the
● 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>]
