Linear feedrate (G94) active
● Machine axes
The velocity is determined by the following setting data:
– For linear axes:
– For rotary axes:
If "0" is entered in SD41110/SD41130, the axis-specific machine data takes effect:
MD32020 $MA_JOG_VELO (conventional axis velocity)
The default setting for feedrate velocity unit is mm/min or rpm for rotary axes.
● Spindles
The velocity applied for the manual traversing of the spindles is defined by the setting data:
SD41200 $SN_JOG_SPIND_SET_VELO (speed of spindle in JOG mode)
If "0" is entered in SD41200, the axis-specific machine data takes effect:
MD32020 $_MA_JOG_VELO (conventional axis velocity)
The maximum speeds of the active gear stage are considered when manually traversing a
spindle.

● Geometry axes
The velocity applied for the manual traversing of geometry axes is defined by the channel-
specific machine data:
MD21165 $MC_JOG_VELO_GEO (conventional velocity for geometry axes)
● Orientation axes
The velocity applied for the manual traversing of orientation axes is defined by the channel-
specific machine data:
MD21155 $MC_JOG_VELO_ORI (conventional velocity for orientation axes)
Revolutional feedrate (G95) active
The feedrate value (in mm/rev.) is defined by the following setting data:
SD41120 $SN_JOG_REV_SET_VELO (revolutional feedrate of axes in JOG)
If "0" is entered in SD41120, the axis-specific machine data takes effect:
MD32050 $MD_JOG_REV_VELO (revolutional feedrate for JOG)
