Drf Offset - Siemens SINUMERIK 840D sl Function Manual

H1: Manual and handwheel travel
4.13 Use of handwheels in automatic mode
When the simulation is deselected or the direction is changed, the current movement is
decelerated using a braking ramp.
Note
The override is effective as for NC-program execution.
Supplementary conditions
● Requirements
Fixed feedrate, dry-run feedrate, thread cutting, or tapping must not be selected.
● Limit values
The acceleration and velocity of the axes are limited to the values defined in the machine
data.
● Interruption of traversing movement
On NC Stop, the function remains selected but the handwheel pulses are not summated
and are ineffective.
Requirement: MD32084 $MA_HANDWH_CHAN_STOP_COND bit 2 = 1
DRF
A selected DRF function also has a path-override action.
● Channel-specific deletion distance-to-go
This causes the movement triggered by the contour handwheel to be aborted; the axes are
decelerated and the program is restarted with the next NC block. The contour handwheel
then becomes effective again.
4.13.3

DRF offset

Function
The "DRF offset" function (differential resolver function) can be used to set an additive
incremental zero offset in respect of geometry and auxiliary axes in the basic coordinate system
in AUTOMATIC mode via an electronic handwheel.
The handwheel assignment, i.e. the assignment of the handwheel from which the increments
for the DRF offset are to be derived, to the geometry or auxiliary axes that are to be moved by
this, must be performed via the appropriate machine axes. The appropriate machine axes are
those to which the geometry or auxiliary axis is mapped.
The DRF offset is not displayed in the axis actual-value display.
