P1: Transverse axes
12.1 Function
Several transverse axes in the channel
The introduction several transverse axes in the channel involves a functional decoupling of
diameter programming and reference axis for G96/G961/G962. Diameter programming and
reference axis for G96/G961/G962 can be active for different transverse axes (see table below).

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 817)"), 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:
– Increments for incremental dimension (INC) and handwheel travel (dependent upon
