Need Help!- 197 C-AXIS COMMANDED IN SPINDLE MODE

[padobranac]

Machine is lathe Romi G15SM
Control Fanuc 18i-TA
Alarm: 197 C-AXIS COMMANDED IN SPINDLE MODE

Here is whole program.
Machine stops and alarms at point "PROBLEM" in red color.
When machine reads this line "G0 X0", in DISTANCE TO GO there is value for X and C. Obviously it thinks it is still in circular interpolation?!

Anyway, I have to push RESET, go to line "(CENTER DRILL 8 TM)" and than run program.
There is same thing lower in the program (C-mode with circular interpolation and spindle mode after it), but there is no problem, no alarm.

I attached M-code list of machine.

I dont see a M43 C axis connect......

I think this is not used on my machine...
For M43 manual says "Chuck Clean Off".

I have done pretty much programing (cutting) with C-axis since now, always using same principle, and never had problem like this.

try to put M3 before G0 X0 (PROBLEM)

[Ozemale6t9]

Looks ok to me. My only question would be is the line definitely G0 X0 and not C0 X0 in the machine?

Tried this before and now again, doesn't help.

It is G0 X0 for sure. In other case, when I push RESET and continue program from this tool, at line (CENTER DRILL 8 TM), it would alarm again.
But when I do that program runs OK.

[padobranac]

Any other ideas?

I have tried to put G1 X0 F1 instead of G0 X0 but no help.
I tried to put some other value for X different than 0. No help.

In every case when machine reads this line in Distance to go there is value for X and for C. And alarm.

After pressing OK and starting program from this line again, everything is OK... until it comes to this line again (after one cycle).

When you get the alarm, is G13.1 active?

Very good question. I have not checked it before.
Now I see that G13.1 IS ACTIVE when I get alarm.
It means that circular interpolation is CANCELED.

So why it wants to move "X and C" when I give X...
