Fanuc 21i-T: Swarf conveyor is not running alarm

[Jaanyaar]

Hi!

The swarf conveyor is not installed on the lathe machine. It is not used at all. The problem is when a program runs, that alarm message will be shown on the screen. Operator has to change the page every time. How is it possible to remove that alarm message forever? By changing a parameter or...?

Colchester lathe 220 - Fanuc 21i-T

Thanks in advance.

You would need to look at the manual for the machine. More specifically, the keep relays in the pmc parameters. There might be one that disables the conveyor message.

Thank you!
I looked at the manual and found this:
I know how to manipulate system parameters but have never had any experience with ladder and pmc paramters. Can I do it myself by your explanations and guidance?

It looks like if you turned off keeper relay K1 bit 7 (1xxxxxxx) to a 0 (0xxxxxxx), the alarm should not appear.

Is there any step by step manual for reaching to that relay and editing it? I've never edited ladder.

put machine in MDI
hit offset/settings button, and go to settings
top line should be parameter write enable (PWE). set it to 1. this will generate alarm 100. this is normal

hit the SYSTEM button.
on the screen, you should see the PMC button, hit that.
on that screen, you should see PMCPRM, hit that
on that screen you should see KEEPRL, hit that
cursor down to K01 and highlight the leftmost bit, it will be a 1. you need to change it to a 0 (it will be 1xxxxxxx, change to 0xxxxxxx). DO NOT CHANGE ANY OTHER BIT. I would advise you take pictures of the screen in case you change the wrong thing, you can put it back the way you found it if it doesn't work.

after that, go back to the settings page and turn PWE back to 0. then hit reset to clear the alarm.



Edit: was supposed to be k01, not k07

Much appreciated for your detailed instructions. Learned something new.

I checked K07, all bits were 0. Should I try to change K1 keep relay?

you want to change K01 bit 7 (1xxxxxxx) to (0xxxxxxx)

not k7, k1.
