MD 840C (T)
5000 0000 0100
5001 0000 0011
Name of radius and chamfer for:
• Contour definition
• Circular-path programming
• Polar coordinates
• Name for approach path with soft approach and exit contour (G147, G247, G347, G48,
G148, G248, G348)
3 2 1 0
Bit-No.
Address name
Code:
X = 0000
Y = 0001
Examples:
Z = 0010
0100 = B
A = 0011
0110 = U
B = 0100
C = 0101
U = 0110
V = 0111
W = 1000
Q = 1001
E = 1010
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.
