2.4.2.2 Fine offset
Parameterization
The corresponding fine offset parameterization takes place through the machine data:
MD18600 $MN_MM_FRAME_FINE_TRANS (fine offset in FRAME (SRAM))
Value Significance
0
The fine offset cannot be entered or programmed.
1 Fine offset possible for settable frames, basic frames and the prog. frame via command or
program.
Programming
The fine offset can be programmed in the program using command
CFINE
(
x
, ..,
y,
...). The
coarse offset is defined with
CTRANS
(...). Coarse and fine offset add up to the total offset.
$P_UBFR = CTRANS(x, 10) : CFINE(x, 0.1) : CROT(x, 45)
$P_UIFR[1]=CFINE(x, 0.5, y, 1.0, z, 0.1)
Access to the individual components of the fine offset is achieved through component
specification FI.
finex = $P_UIFR[ $P_UIFRNUM, x, FI ]
Fine offestting can be programmed only if:
MD18600 $MN_FRAME_FINE_TRANS = 1
if this is not the case, then each assignment of a fine offset to a settable frame and to the
basic frame with the alarm "FRAME: fine offset not possible".
A fine offset changed by the operator does not apply until after activation of the
corresponding frame, i.e., activation via
G500
,
G54
to
G599
.
Once activated, a fine offset of a frame remains active the whole time the frame is active.
When the offset of the current frame is displayed, the total offset (coarse offset and fine
offset) is output.
