Hi guys, I'm having some intermitent low APC battery issues with a fanuc alpha-i servo amp, which stops the z-axis motor from moving mid cycle. It happens only on 1 of the servo amp (we have 8 units and each controls 3 axis motors) during a z-axis lowering movement. I've tried replacing the batteries, but the APC was flashing on the PC screen and intermittently stopping the servo motor from moving.

I've also replaced the cable connecting the motor and amp, and also replaced the servo motor unit.

Can you please help me as I'm running out of ideas.

Is there anything else I should try?

Thanks for help 😁🙏
