6.10 Deselect DRF (handwheel) offsets, overlaid motions and transformation (DRFOF, CORROF, TRAFOOF)
CORROF()
Or
TRAFOOF
Parameters
Modal deactivation:
DRFOF
CORROF(axis,DRF[AXIS
,AA_OFF])
CORROF(axis)
TRAFOOF
Axis
String == DRF
String == AA_OFF
The following expansions are possible:
String == ETRANS
String == FTOCOF,
For more information about TRAFOOF, see
/PGA/Programming Guide Advanced, Chapter "Deselecting Transformations (TRAFOOF)".
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")
6-40
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
Deactivate transformation
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()
