Name of radius and chamfer for: Name of angle for:
• Contour definition • Contour definition
• Circular-path programming • Polar coordinates
• Polar coordinates
• Name for approach path with soft approach and exit contour (G147, G247, G347, G48,
G148, G248, G348)

Address name
Code:
X = 0000
Y = 0001
Z = 0010
A = 0011
B = 0100
C = 0101
U = 0110
V = 0111
W = 1000
Q = 1001
E = 1010
Valid names for axes, angles, chamfer and radius
A Assignable address N Subordinate block
B Assignable address O Danger of confusion with 0 (zero)
C Assignable address P No. of subroutine passes
D Tool offset Q Assignable address
E Assignable address R Arithmetic parameter
F Feed S Spindle speed, S function
G G function T Tool
H H function U Assignable address
I Interpolation parameter V Assignable address
J Interpolation parameter W Assignable address
K Interpolation parameter X Assignable address
L Subprogram (subroutine) Y Assignable address
M M function Z Assignable address
Examples:
0100 = B
0110 = U
Bit-No.
The names in MD 5000, MD 5001 and 568* must not overlap. An identical axis name with
different extended address is not regarded as overlap.
Note:
If the value 0 ( ˆ = address name X) is entered in MD 5000/5001, the programmed dwell time
must not be programmed in G04 X... .
Remedy: Program dwell under G04 F... .
Active: In next block.
