Just received an Arrow 500 with A2100 that was abused during shipping. Tool changer cover broke off, doors knocked off the rails, hard disk crashed. At first, that is all I thought was wrong but now that I have a new HDD, there is something wrong with the spindle...
If I start the spindle above 650 RPM, it sounds like it skips or has crap loose inside the motor as it comes up to speed. The spindle itself sounds fine but the motor is making the noise. I also get the noise if I change the spindle speed rapidly with the pendant override. Once at speed, it's whisper quiet.
My question, what could have gone wrong in the spindle motor?
Does anyone have a parts breakdown of it? Label says it's a 1-604-0002
Does it require special tools to disassemble or should I just send it in for repair?
Could it be the electronics?
