X:

1->Former half of G101 tool path generation operation

2->Latter half of G101 tool path generation operation

3->Former half of G102 (G103) tool path generation operation

4->Latter half of G102 (G103) tool path generation operation

2->Latter half of G101 tool path generation operation

3->Former half of G102 (G103) tool path generation operation

4->Latter half of G102 (G103) tool path generation operation

**Probable Faulty Locations**

This alarm is set taking the following possibility into consideration, and does not occur in normal conditions.

During calculation processing in the NC, calculation might become impossible due to the influence of calculation error.

**Measures to Take**

Change the command value in the program within an allowable range.
