Detailed Description
2.4 Frames
2.4.3 Frame components
2.4.3.1 Translation
The program commands below are used to program the translation:
$P_UIFR[1] = CTRANS(x,10,y,10)
$P_UIFR[1,x,tr] = 10
TRANS x = 10 y = 10
2.4.3.2 Fine offset
The machine data
MD18600 $MN_MM_FRAME_FINE_TRANS
can be used to configure the fine offset as follows:
0:
1:
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 ]
2-40
The fine offset cannot be entered or programmed.
Fine offset possible for settable frames, basic frames and the prog. frame via command or
program.
