Okuma Alarm-B 2257 Mistake in gauging cycle command
In G30 gauging cycle, the D command value is larger than the distance between the starting point and the point to be measured.
Or, the CD command value is larger than the relative distance from the cycle start point to the target point.

X
X=1 ->A value of D instruction is bigger than a distance during start point and measure point in G30 measure cycles.
X=2 ->In G30 measure cycles of C axis, a distance to the virtual target point which added a value of CL instruction to target
point from start point amounted to 360 times more than.
X=3->In G30 measure cycles of C axis, a value of CD instruction is bigger than a distance during start point and measure
point.
Probable Faulty Locations
1)D instruction program example of G30 measure cycles
G00 X50 Z100 G30 Z90 D20 L20
2)CL instruction program example of G30 measure cycles
G00 C0 G30 C270 CD=5 CL=120
3)CD instruction program example of G30 measure cycles
G00 C0 G30 C90 CD=95 CL=10
Measures to Take
1)They make D instruction smaller than a distance during start point and measure point.
Or, start point is turned into a this side more.
2)The target point which makes CL instruction small is neighborhood on start point more.
Usual G00 C0 G30 C270 CD=5 CL=80
3)They make CD instruction smaller than a distance during start point and measure point.
Or, start point is turned into a this side more.
Usual G00 C0 G30 C90 CD=80 CL=10
