FH/FZ5 Processing Item Function Reference Manual
2) Sampling measurement is executed.
3) Calibration is executed from the sampling
result, conve
rts sampling position to
coordinate.
4) Calculates the absolute value’ s distance of
refe
rence position and reverse rotation
point.
5) Defines the maximum value of X coordinate
side as X-i
naccuracy, and the maximum
value of Y coordinate side as Y-inaccuracy.
• X-inaccuracy is given the more larger
val
ue of [X+a1-X1] or [X+a2-X2].
• Y-inaccuracy is given the more
lar
ger
value of [Y+b1-Y1] or [Y+a2-Y2].
