Fanuc i series look ahead function problem

[Greg_J]

Hello,

I'm doing some rotary roughing and the motion is pretty choppy and I thought using the look ahead function would help. Using G05 P1 R1 I noticed it ran smoother and quicker then with out but my problem starts when the machine starts to use the "A" axis I get an error.

PS 5011 Parameter Zero (max cut)

I look for that parameter (01432) max cut feedrate (bipl) and it is set to zero so I change it to match the max cut feed rate on (01430) and when I run the program it changes back to 0 and gives me the same alarm.

Any ideas where it's getting the 0 from to over write the value I put in?

Also what does bipl stand for?

 

Thanks,

Greg

You need to look at 8465 and 8466, see if they are zero, if they are.  Then look at 13626 and 13627.  They are the R1 and R10 values that will be interpolated depending on if you select something other than 1 or 10 and written to 1432.  If they are zero when you command R1 it will write them to zero.  You may need to setup all of the 13600 parameters if you want to use R1-R10.  Otherwise you will want to not use that code and restore your original settings.

Thanks for the info.

 

I was thinking that on this machine that the "A" axis wasn't supported cause all the settings were set to 0. I'll keep looking into it.

 

Do the parameters tell you the tolerance for 1-10 settings?

No, but its not terribly hard to get some values that will work well for you.  What is the machine?

Doosan Mynx 6500/50 with Fanuc i series controller.

0i or 31i?  i doesn't mean much.

I believe it is 0i.

[Greg_J]

I think Rekd is right, but I can't see any where it actually says what it is

Go to System, PMC Config. Amd yiu should be able to tell control.
