One of our mills started alarming out this morning, alarm 212 "magazine fault" or something similar. It turns out the battery for one of the two ATC drives was dead so I changed it.
After changing the battery the drive is stuck in an alarm mode, Z1-N1 01 which the book for the drive says is "absolute position detector data lost." The solution is listed as initialize the zero point, but it's pretty vague as how to do that exactly.
The machine will not move at all from commands in the ATC menu, nor does it have a "magazine zero return" option like all the M+ mills I'm used to. It does have a "F1" menu that seems to control tool change components manually (or without PLC checks or something.) If you hold the "magazine forward/reverse" buttons on either of these pages the belt will turn ever so slowly. I've taken the belt around twice both directions to see if it would eventually home but it never does. I've got a few M codes I'd like to try, but MDI mode is largely useless because the alarm resets itself instantly after it is cleared and I've yet to get anything going.
I've also read that there may be a reset or override switch in the cabinet to bring the belt around to tool 1 but my machine doesn't have that switch. I've let both drives discharge completely a few times after I swapped the battery but that doesn't seem to change anything. I even got desperate enough to swap batteries between both drives but the alarm is still there...
For some reason (only because I spent way too much time crawling through menus on the mill and PDF's for servo drives) I think this can only be reset by getting directly at the drive from a PC over a serial connection. There's a round DIP switch (Not sure if that's the correct term.) and the manual says that a certain position on that switch is an initialization setting but that it clears all loaded parameters. I'm almost positive that's a bad idea so I haven't done that yet.
So is it possible that the drive just needs all of it's parameters reloaded? The mill was running fine a few hours this morning till it threw this alarm. I swapped the battery within an hour and had the machine on when I did. It was low though, so I guess some parameters could have been lost.
Does anyone else have any experience with a deal like this? I'd greatly appreciate any insight!!
Thanks!
