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.
