Velocity
The velocity for a JOG traversing movement is determined by the following value settings
depending on the feedrate mode:
● Linear feedrate (G94) is active (SD41100 $SN_JOG_REV_IS_ACTIVE = 0):
● Revolutional feedrate (G95) is active (SD41100 $SN_JOG_REV_IS_ACTIVE = 1):
The default setting for feedrate velocity is mm/min or rpm for revolutional feedrate or rotary
axes.
Note
Because of the limited feedrate, the axis is not able to follow the handwheel rotation
synchronously, especially in the case of a large pulse weighting, and therefore overtravels.
Rapid traverse override
If the traversing key is also actuated together with the rapid traverse override key, the
movement will be made with the configured rapid traverse velocity:
● MD32010 $MA_JOG_VELO_RAPID (rapid traverse in jog mode)
● MD32040 $MA_JOG_REV_VELO_RAPID (rapid traverse, revolutional feedrate)
Feedrate override
The traversing velocity for JOG can also be influenced using the axial feedrate override
switch provided that the following NC/PLC interface signal is set:
DB31, ... DBX1.7 (axial feedrate override active)
Percentages are assigned to the individual feedrate override switch positions via machine
data. For a switch position of 0% the axis is not traversed, provided that 0 is entered in the
associated machine data.
