Hi fired up my Hitachi Seiki lathe today after it has sat idle for some time.
First I got a battery alarm on the Micon8 controller. So I swapped the batteries whilst the machine was switched on and now it seems to work fine. I can search for data adresses and check machine states etc.

I can home and jog the machine, all looks good with no alarms on the Fanuc side.

But I can't run anything from MDI and I can't run a program.

I have a power alarm on the Micon8. On 28A all the digits are 1 accept the 24v which is 0 and ok.

But have checked all the power supplies and all are ok.

Is the Micon a programable controller with ladders on it? Wondering if I've lost the ladders when the battery went low?

There is no Fanuc PC model A or B board in the machine and none showing in the diagnostics..could it be missing?

The MDI start key is showing as working in the diag screen. The cycle start button is not showing as working but the reset button is. I can't jog the spindle from the manual control panel but most of the other buttons and switches work including the foot pedals for the chuck.

I can read from tape in memory mode as well.

Thanks in advance for any help I'm really lost on this one!!
