6.10 Deselect DRF (handwheel) offsets, overlaid motions (DRFOF, CORROF)
For instance, if a particular axis with an overlaid motion or a position offset interpolates, the
instruction CORRROF can be used to deactivate either the DRF offsets or the position offset
for this axis. The axis is not traversed.
Programming
DRFOF
Or
CORROF(axis,string[axis,string])
Or
CORROF(axis,string)
Or
CORROF(axis)
Or
CORROF()
Parameters
Modal deactivation:
DRFOF
CORROF(axis,DRF[AXIS
,AA_OFF])
CORROF(axis)
Axis
String == DRF
String == AA_OFF
The following expansions are possible:
String == ETRANS
String == FTOCOF,
Example of axial DRF deselection
A DRF offset is generated in the X axis by DRF handwheel traversal. No DRF offsets are
operative for any other axes in the channel.
N10 CORROF(X,"DRF") acts like DRFOF( )
A DRF offset is generated in the X and Y axes by DRF handwheel traversal. No DRF offsets
are operative for any other axes in the channel.
N10 CORROF(X,"DRF")
266
Deactivation (deselection) of DRF handwheel offsets for all active axes in
the channel
Deactivation (deselection) of axial DRF offsets and the position offset for
individual axes as a result of $AA_OFF
All active overlaid motions are deselected
Axis identifiers (for channel, geometry or machine axis)
DRF offset of axis is deselected
Position offset of axis is deselected due to $AA_OFF
An active zero offset is deselected
Acts like FTOCOF (deactivate online tool offset)
;Only the DRF offset of the X axis is deselected, the
;X axis does not move
;The DRF offset of the Y axis is ;retained
;Both offsets would have been deselected with
;DRFOF()
