3 Axis Fanuc controller Loosing home when powered off?
This is a stupid question, but we have been stumped.
For some time now, if we are to power our machine off, we will loose x, y, and z home position. It is a Murata Dual spindle with a gantry system, it runs off of a Fanuc 18i-T controller, and the servo drive for the gantry is a Fanuc A06B-6096-H303. We have swapped the servo amp, power supply, battries, and I don't even remember what else. I know it is getting good power from the power supply, both on the bus line, and within the 24 volt circuit. But I wonder about the encoder cables, could that be where there is a short, and not letting the system charge the battries, as well as holding a charge?
But, at a loss here....And would love to have any help.

I have the same problem on a Doosan with Fanuc control & servo drives. We can't find those batteries on the servo drives. Would the batteries be under the red cap of the servo motors ?

The battery is not on the motor.
Under the yellow bulged out cover, it says battery right below it. It plugs into the CX5X or CX5Y right next to it.

Some newer systems don't have the yellow sticker, and are just a rounded bulged out grey cover.
If you still can't find it, be sure to post what fanuc control your machine uses, and/or a picture of your drives.
