We have a #445 Y axis soft disconnect alarm that is driving us nuts trying to figure out what the problem is. Fanuc doesn't seem to have a definate answer other than maybe replace the servo which we did. Anyone have this problem?

Does this problem happen during a zero return? If not what condition is the machine in when you see it the most?

As soon as you turn on the machine the alarm is there. It was first a hard disconnect now it's a soft disconnect after replacing the servo amplifier.
fastolds,
Test the encoder cable from the motor back to the servo. I bet you some sort of problem there. I may have the servo parameter default setting if you would like to double check them against settings you currently have. I would need the motor & amp numbers. Also, are you sure the alarm is 445? This code does not match the problem you are having.
Let me know if I can help.

445 is a soft dissconect that is correct acording to my handy Fanuc miniguid here.
You got a bad encoder cable. Try swaping it with the X axis servo and see if the alarm transfers to the X axis. That is the quickest way if you do not have a spare cable.
