Revolutional feedrate
In JOG mode the behavior of the axis/spindle also depends on the setting of SD41100
JOG_REV_IS_ACTIVE (revolutional feedrate when JOG active).
● If this setting data is active, an axis/spindle is always moved with revolutional feedrate
MD32050 $MA_JOG_REV_VELO (revolutional feedrate with JOG) or MD32040
$MA_JOG_REV_VELO_RAPID (revolutional feedrate with JOG with rapid traverse
overlay) as a function of the master spindle.
● If the setting data is not active, the behavior of the axis/spindle depends on SD43300
$SA_ASSIG_FEED_PER_REV_SOURCE (revolutional feedrate for positioning
axes/spindles)
● If the setting data is not active, the behavior of a geometry axis on which a frame with
rotation is effective depends on the channel-specific setting data SD42600
$SC_JOG_FEED_PER_REV_SOURCE. (In the operating mode JOG, revolutional
feedrate for geometry axes on which a frame with rotation is effective.)
Maximum axial acceleration
With positioning axis motions, one of the two following maximum values is effective
depending on the set positioning axis dynamic response mode:
● MD32300 $MA_MAX_AX_ACCEL [0] (maximum axial acceleration for path motions in the
dynamic response mode DYNNORM)
● MD32300 $MA_MAX_AX_ACCEL [1] (maximum axial acceleration for path motions in the
dynamic response mode DYNPOS)
The positioning axis dynamic response mode is set in the NC-specific machine data:
MD18960 $MN_POS_DYN_MODE = <mode>
<mode> Meaning
0 Effective maximum axial acceleration: MD32300 $MA_MAX_AX_ACCEL[ 0 ]
1 Effective maximum axial acceleration: MD32300 $MA_MAX_AX_ACCEL[ 1 ]
Maximum axial jerk
When traversing positioning axes with active jerk limitation, the value from one of the
following machine data takes effect as maximum axial jerk:
● MD32430 $MA_JOG_AND_POS_MAX_JERK (maximum axial jerk for positioning axis
motions)
● MD32431 $MA_MAX_AX_JERK [0] (maximum axial jerk for path motions in the dynamic
response mode DYNNORM)
● MD32431 $MA_MAX_AX_JERK [1] (maximum axial jerk for path motions in the dynamic
response mode DYNPOS)
