Maximum velocity and acceleration
The velocity and acceleration used during manual travel are defined by the startup engineer
for specific axes using machine data. The control limits the values acting on the axes to the
maximum velocity and acceleration specifications.

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".

Response (K1)
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).
