Setting data
Revolutional feedrate in JOG mode
The behavior of an axis in terms of its revolutional feedrate relative to the master spindle of the
channel to which the axis is currently assigned in JOG mode depends on the settings in the NC-
specific setting data:
SD41100 $SN_JOG_REV_IS_ACTIVE, Bit <x>
Bit
2
3
1) The function is active in addition to the setting in bit 1.
NC/PLC interface signals
● Revolutional feedrate active (channel-specific)
The interface signal indicates that axes are traversed with revolutional feedrate in the
channel:
– AUTOMATIC mode: Path or synchronized axes
– JOG mode: Geometry axes
DB31, ... DBX62.2 == 1 (revolutional feedrate active)
● Revolutional feedrate active (axis-specific)
The interface signal indicates that the axis is traversed with revolutional feedrate:
DB31, ... DBX33.2 == 1 (revolutional feedrate active)

Value Meaning
0 0 The behavior depends on further setting data, depending on the function of the axis:
● Axis / spindle: SD43300 $SA_ASSIGN_FEED_PER_REV_SOURCE
● Geometry axis on which a frame with rotation acts: SD42600
$SC_JOG_FEED_PER_REV_SOURCE
● Orientation axis: SD42600 $SC_JOG_FEED_PER_REV_SOURCE
1 The axis is traversed with the revolutional feedrate.
Boundary condition
Traversing is performed without the revolutional feedrate if the following applies:
● Axis / spindle: The master spindle is stationary AND SD43300
$SA_ASSIGN_FEED_PER_REV_SOURCE == -3
● Geometry axis on which a frame with rotation acts: The master spindle is
stationary AND SD42600 $SC_JOG_FEED_PER_REV_SOURCE == -3
● Orientation axis: The master spindle is stationary AND SD42600
$SC_JOG_FEED_PER_REV_SOURCE == -3
1 0 In rapid traverse, traversing is performed with the revolutional feedrate.
1 In rapid traverse, traversing is performed without the revolutional feedrate.
0 In handwheel jogging, traversing is performed with the revolutional feedrate.
1)
1 In handwheel jogging, traversing is performed without the revolutional feedrate.
0 In DRF handwheel traversing, traversing is performed with the revolutional feedrate.
1)
1 In DRF handwheel traversing, traversing is performed without the revolutional fee‐
drate.
