PROGRAMMING14. COMPENSATION FUNCTION
B–63534EN/02
390
Parameter
Parameter 7580=4 (C–axis)
Parameter 7581=1 (X–axis)
Parameter 7582=2 (Y–axis)
Parameter 7583 to 7588=0
Parameter 7575#0(X)=1 (The offset is valid for the X–axis.)
7575#0(Y)=1 (The offset is valid for the Y–axis.)
7570#0=0 (When bit 0 of parameter 7570 is set to 1, the values in
square brackets ([ ]) are calculated.)
Data of fixture offset 1 (n = 1)
C= 180.0 (reference angle)
X= –10.0
Y= 0.0
When these parameters and data are set, the machine operates as shown
below :
