Fixed addresses
The following addresses are set permanently:
Address Meaning (default setting)
D Cutting edge number
F Feed
G Preparatory function
H Auxiliary function
L Subprogram call
M Miscellaneous (i.e., special) function
N Subblock
P Number of program passes
R Arithmetic variables
S Spindle speed
T Tool number
: Main block
Example for programming:
N10 G54 T9 D2
Fixed addresses with axis extension
Address Meaning (default setting)
AX Axis value (variable axis programming)
ACC Axial acceleration
FA Axial feed
FDA Axis feed for handwheel override
FL Axial feed limit
IP Interpolation parameter (variable axis programming)
OVRA Axial override
PO Polynomial coefficient
POS Position axis
POSA Positioning axis across block boundary
Example:
N10 POS[X]=100
Explanation:
When programming with the axis extension, the axis to be traversed is enclosed in square
brackets.
You will find a complete list of all fixed addresses in the Appendix.
