Mazak QT350M/640T C axis parameter

[Zoffen]

I'm having some trouble with a Mazak lathe at work.

 

With the axis @ C0.0, if i MDI C10.0, then C5.0, the machine will go to C10.0 in the positive directions, then go to C5.0 but go all the way around in the positive direction instead of going in the negative direction.

 

Is there a parameter i can change to force the C to go to that absolute position in the shortest direction?

Also, how do you all like to program your c for c-x contour moves? This is all a learning experience so anything helps lol!

thankx!

By inputting C10. Then C5. you are telling it to go the long way what you need to input is C10. then C-355. to get it to move just the 5 deg. To get a neg rotation you must give it a neg # (C-360. + the finish angle you want to be at)

i changed a parameter and it goes the shortest rout now.

i changed a parameter and it goes the shortest rout now.

 

What control and what parameter?

640t.

 

don't remember the param, its in one of the manuals i thinks.
