Okuma Alarm-B 2252 Mistake in arc command
In direct arc radius command, the coordinates of the arc center cannot be calculated from the L command and X and Z commands.
The command error between I and K commands and X and Z commands in circular interpolation exceeds the tolerance(std.:20 um).
Object
SYSTEM
Code
1->L value is smaller than 1/2 of the distance up to the target value.
2->Overflow in calculation of arc center or error
3->Error between the radius which is calculated from I and K commands and the distance between the end point and the center is greater than tolerance.
4->I and K commands are zero.
10->End point of the arc command after calculation of LAP, tool nose radius compensation, or tool offset is offset from the programmed arc more than the specified tolerance.
Probable Faulty Locations
1)I, K, and L commands and X, Z commands in the block containing the G02/G03 code.
Program Example:
Code 1 appears.
G00 X50 Z50 G02 X50 Z0 L20 F0.1 M02
Code 3 appears.
G00 X0 Z100 G02 X105 Z20 K-100 F0.1 M02
Code 3 appears.
G00 X0 Z50 G03 X95 I-1 K-20 F0.1 M02
Measures to Take
1)Change the command value so that an arc can be generated.
