Velocity
The velocity of the axes/spindle during manual traverse in JOG is defined by the following
default values:
● For linear axes with the general SD41110 JOG_SET_VELO (JOG velocity with G94) or
● If the corresponding SD is zero, the appropriate axis-specific MD32020 JOG_VELO
Rapid traverse override
If in the case of machine axes the rapid traverse override key is pressed at the same time as
the traversing keys, then the movement is executed at the rapid traverse velocity set in axis-
specific MD32010 JOG_VELO_RAPID (axis velocity in JOG mode with rapid traverse
override).
The value of the assigned machine axis is used for geometry axes: X->X1, Y->Y1, Z->Z1 (for
default setting). The separate PLC interface area of the geometry axes must be used for
control.
Velocity override
The velocity at which axes traverse in JOG can also be influenced by the axis-specific
feedrate override switch for machine axes, provided that axis-specific IS "Override active"
(V380x 0001.7) is set. If the switch is set at 0%, the axis is not traversed - even if IS
"Override active" is not set.
The channel-specific feedrate override switch applies to geometry axes, or, in the case of
rapid traverse override, the rapid traverse override switch.
The activated spindle override switch applies to the spindle.
Acceleration
The maximum axis acceleration is defined with the axis-specific MD32300 MAX_AX_ACCEL.
The acceleration can also be set via a preset characteristic curve in JOG mode. The
possible settings are described in Chapter "Acceleration (B2)".
PLC interface
A separate PLC interface (VB 3200 1000, ff or VB 3300 1000, ff ) exists for geometry axes
(axes in WCS) that contains the same signals as the axis-specific PLC interface.
When the spindle is traversed manually, the PLC interface signals between the NCK and
PLC have the same effect as for machine axes. Interface signals "Position reached with fine
or coarse exact stop" are only set if the spindle is in position control.

for rotary axes with SD41130 JOG_ROT_AX_SET_VELO (JOG velocity for rotary axes)
or SD41200 JOG_SPIND_SET_VELO (JOG velocity for the spindle).
(conventional axis velocity) applies. In this case, the value of the assigned machine axis
is used for geometry axes: X->X1, Y->Y1, Z->Z1 (for default setting).
