Detailed Description
2.2 Metric/inch measuring system
Velocities, Setpoint/Actual-Value Systems, Closed-Loop Control (G2)
Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
2-15
Example 2:
The definition is made here by programming G71 in the synchronized action.
N100 R1=0
N110 G0 X0 Z0
N120 WAITP(X)
N130 ID=1 WHENEVER $R1==1 DO G71 POS[X]=10
N140 R1=1
N150 G71 Z10 F10 ;Z=10 mm X=10 mm
N160 G70 Z10 F10 ;Z=254 mm X=10 mm (X posit. always at 0 mm)
N170 G71 Z10 F10 ;Z=10 mm X=10 mm
N180 M30
