Batteries

I'm replacing batteries this week. This morning, I powered up a LR Mate with R-J2 Mate Controller. I opened the battery case and got the expected SRVO-065 on all 5 axes. I put fresh batteries in, button it back up, and hit RESET. Still, I have SRVO-065 on all 5 axes. I tried the old batteries again, but could not clear the alarms.

I'm contemplating putting the new batteries back in and just cycling power and hoping for the best.

Has anyone ran into this before?

I Curious about it is a battery fault or a cables? as battery box and it's cover having no any issues.

Can anyone please share Wiring diagram of R30iA Manipulator's Battery box to Controller/Servo Amplifier or This Cable's details. (Battery backup to Servo Amplifier or else)

Thanks in advance.

Hello,

In this case while investigated with Fanuc India team found that Axis#05 pulse coder cable got broken with battery backup wires & after replace it works fine.

Thanks
