Hi all,

I've been trying to get my Okuma Howa Millac 3VA working after sitting idle for some time. Everything seemed to be going well until I tried to do tool changes.

The first problem: I can't get any toolchange related commands to work in MDI mode except for toolpot vertical and horizontal and the interlock bypass commands. Trying to move the arm with M80-81 doesn't work. The control simply hangs up and doesn't respond to cycle start.

The second: I can't even get the tool magazine to set numbers or index the tools using the panel on the side of the machine.

Before this happened I lost all my parameters and programs and had to reset them. The batteries failed after sitting in storage for a while. The toolchanger worked back then, although I'm not sure if the two are related.

I'm at a loss here. Can anyone help me muddle through this?

Thanks,
Will

Ok, I managed to get it to make toolchanges. I still can't get the tool operations panel to actually set tool numbers, so I was going through and trying to retrieve the tools in the magazine...and then I hit m06 without inputting a T code and I got the arm stuck.

Basically, the arm is gripping onto the tool in the spindle, and now won't move. I tried inputting another m6 but all I managed to do was get the pot stuck. After cycling e-stop I managed to clear the toolpot, but the toolchange arm still won't let go / move.

Any ideas?

Ok, I managed to get the ATC arm to move and removed the offending tool. Unfortunately, now the ATC arm doesn't move during a toolchange. Everything operates just fine until it's time for it to move. Last movement before it stops is the toolpot going vertical.

My bad, I didn't reset the operator message with an M02. Seems to work now.

Hello Will, I am glad to see you got your machine up and running. I am hoping you could help me out. I have a Okuma Howa Millac 3VA made in 1985 with a Fanuc 10m controller. Unfortunately the battery warning was ignored and the system parameters were wiped out. Could you please help me out with a backup? Or help me out with some contact information where I could get my hands on some backup parameters? Thanks for posting about your machine as I've had some trouble finding any info on this machine.

Thanks,
Greg
