NC Programming 17VRS Motion Commands, Dimension Inputs
3-21
DOK-MTC200-NC**PRO*V17-ANW1-EN-P
Metric (mm) Programming Input 'G71'
If 'inches is set in the process parameters as the basic programming unit,
the subsequent values are interpreted as millimeter data and are con-
verted to inches internally after G71 has been programmed.
•
Motion commands (coordinate values); for example X127mm is con-
verted to X5 inches.
•
Interpolation parameters I, J and K and radius R;
•
Feed data F and G95 F; for example, F1500 mm/min is internally con-
verted to F59.05 inches/min;
•
Programmable offsets G50, G51 and G52;
•
Motion commands assigned by means of NC-variables (X=@050),
interpolation parameters (I=@051), feedrate information (F=@052)
and programmed offsets (G50 X=@053).
G71 remains in effect until the end of the program or until it is overwritten
by G70.
