FANUC macro program programming 1 . Variable General workpiece program appoints G code and ship distance with numerical value directly; for example, GO1 and X100.0. hen user macro is used, numerical value can !e appointed directly or !y varia!le. hen varia!le is used, varia!le value can !e changed !y program or operation in "#$ panel.

dummy varia!le
%1%((
2ocal varia!le is only used to store data in macroprogram, such as operation outcome hen power is cut, local varia!le is initiali3ed to local varia!le empty. 4nd when macroprogram is called, independent varia!le assign local varia!le.
%100%155 %600%555
common varia!le
7ommon varia!le has the same meaning in different macro program. when power is cut, varia!le %100%155 are initiali3ed to empty. #ata of varia!le %600%555 is stored even if power is cut.

system varia!le
8ystem varia!le is used to read and write transformation of all kinds of data when 77 is running, such as tool current position and compensation value.
he varia!le is always empty, no value is assigned to the varia!le.
variable value range
2ocal varia!le and common varia!le can have value 0 or values as following shows9 10: to 10&5 or 10& to 10: $f output oversteps effective range, <=8 warning O.111 is issued. Decimal omission
hen varia!le value is defined in program, decimal can !e ignored. 'or example ： hen define %1 ＝ 1&( ； actual value of varia!le %1 is 1&(.000. Variable citation
o use varia!le value in program, varia!le num!er follows it after appointing. when using expression to specify varia!le, put expression in !racket. 'or example ： G01X%1-%&/'%(; 7ited varia!le value is rounded automatically according to minimum setting unit. 'or example ： hen G00X% is executed as 1= 1000mm , 77 assign 1&(:6> to %1, and actual a ctual instruction value is G00X1&(:>. o change the sign of cited varia!le, put negative sign !efore %. 'or example ： G00X － %1 hen you cite undefined varia!le, varia!le and address are all ignored. 'or example ： hen value of varia!le %1 is 0 and value of %& is empty, the executing outcome of G00X%1 ?% & is G00X0. Common variable of double locus(double locus control

hen varia!le value is undefined, this varia!le !ecomes empty varia!le. )aria!le %0 is always empty. 4nd it can not !e written !ut only !e read. Citation
