Dear All
Wonder if you can point me to the correct direction.
Have a Mori MC-55 with a Fanuc a06b-6044-h010 Spindle Drive
Machine use to work and we recently we get Alarm #2 when we send a speed signal to the drive. Drive will not alarm if we send S000.
Disconnect motor with same result
So far. Check fuses, rectifiers, IGBT all are fine.
Check clock and DC voltage and they are fine.
While we were trouble shooting today. It threw alarm 1 and 4 upon power up. . Check overheat switch and we get a continuity at the Honda connector. Pulled main board and notice a metal chip stuck in the back. Pulled chicp, clean board, e-prom and re intall board. Still have alarm 1 and 4.
What is next?
