I have a mid 80's Hurco BMC-30, with a Fanuc Drive. I have an error: Spindle Drive Fault Check Drive System. When this happens there is an AL 02 code on the drive. I have a real nice Hurco repairman who knows that I can do most of these repairs myself I am just not very good at diagnosing the problem yet. He hooked me up with a guy from a place called Precision Zone inc, in Wheeling, IL. who said my drive was bad. I ordered one from him and replaced it. That was not the issue, it does the same thing. He mentioned something about the encoder being bad and he took the drive back. My questions are: Does anyone know where the encoder might be located I can't find it listed anywhere in the manual and maybe a good place to get one? If it is located in the motor itself should I just replace the whole motor? Any help will be great.
Thanks,
John
