Unknown variable.
Description | When linking V.G.NP[...].ALL, an invalid operation is programmed on the right side of an assignment. A linkage with axis specific constants or variables is not permitted. Example: Wrong: N10 G00 X0 Y0 Z0 N20 V.G.NP[1].ALL = V.G.NP[2].ALL + 100

:

N1000 M30

Correct:

N10 G00 X0 Y0 Z0

N20 V.G.NP[1].ALL = V.G.NP[2].ALL

N30 V.G.NP[1].V.X += 100

:

`N1000 M30`

Response | Class | 2 | Abort NC program processing.
Solution | Class | 3 | Check and modify NC program. Apply linking rules correctly to .ALL variables [PROG// Section: Adding and subtracting offsets].
Error type | 1, Error message from NC program.
