B axis invert
B axis invert
(OP)
We keep getting this alarm. I finally pulled the b axis motor and it seems very stiff to turn by hand. its a Fanuc A06B-0115-B103. Does anyone know if that is normal?
Thanks

If the alarm happens all the time, I would pull the motor and run it back and fourth in manual mode and see if it behave the same way.
If it's on the FO-NT, it could be debris in and around the lens assembly area that's binding things up.
Also, there is a red anodized aparture under the lens cartridge that can come loose and bind things up. Pull the cone off and make sure it's in all the way.

If that is okay, it's possible that the power wire that goes to the motor is broken somewhere.
I understand your concern about the servo amplifier. It is a possibility, but in 17 years, I have only replaced a couple of them, usually it's a problem with the encoder side of it.

Did you say you unhooked the motor? Is it possible that your back up battery has gone bad and lost your b-axis ref. point? I had this happen as well on our FOM23015NT.
