5.3 Coarse and fine offsets (CFINE, CTRANS)
Function
Fine offset
A fine offset of the basic frames and of all other settable frames can be programmed with
command CFINE (X, ..,Y, ...).
A fine offset can only be made if MD18600 $MN_MM_FRAME_FINE_TRANS=1.
Rough offset
The coarse offset is defined with CTRANS(...).
Coarse and fine offset add up to the total offset.
Syntax
$P_UBFR=CTRANS(x, 10) :
CFINE(x, 0.1) : CROT(x, 45)
$P_UIFR[1]=CFINE(x, 0.5 y,
1.0, z, 0.1)
Access to the individual components of the fine offset is achieved through component
specification FI (Translation Fine).
DEF REAL FINEX
FINEX=$P_UIFR[$P_UIFNUM, x, FI]
FINEX=$P_UIFR[3, x, FI]$P
