Mode change from JOG to AUT or from JOG to MDI
It is possible to switch operating modes from JOG to AUT or MDI only if all axes in the
channel have reached "coarse exact stop".

Rotational feedrate active in JOG
In JOG mode, it is also possible to traverse an axis manually at a revolutional feedrate (as
for G95) specific to the current speed of the master spindle.
It is activated via setting data
SD41100 $SN_JOG_REV_IS_ACTIVE (JOG: revolutional/linear feedrate).
The feedrate value (in mm/rev) used can be defined as follows:
● Using general setting data
● Via axial machine data
If a master spindle has not been defined and the axis is to be traversed in JOG at a
revolutional feedrate, alarm 20055 is output (alarm 20065 for geometry axes).
Transverse axes
If a geometry axis is defined as a transverse axis and radius programming is selected
(MD20100 $MC_DIAMETER_AX_DEF (geometry axes with transverse-axis functions)),
the following features should be observed when traversing in JOG:
● Continuous travel:
● Incremental travel:
● Traversing with the handwheel:

SD41120 $SN_JOG_REV_SET_VELO (JOG velocity for G95)
MD32050 $MA_JOG_REV_VELO (revolutional feedrate in JOG)
or for rapid traverse override:
MD32040 $MA_JOG_REV_VELO_RAPID
(revolutional feedrate in JOG with rapid traverse override),
if SD41120 = 0
There are no differences when a transverse axis is traversed continuously.
Only half the distance of the selected increment size is traversed. For example, with
INC10 the axis only traverses 5 increments when the traversing key is pressed.
As for incremental travel, with the handwheel only half the distance is traversed per
handwheel pulse.
