It is a 10hp 15k Yaskawa with a lot of hours on it. It is a 2001 that supposedly ran 24/365 for 10 years before I bought it in 2013. The spindle inverter, a VS-626M5, was repaired in 2012 but I have no idea what went wrong. When I bought it the inverter had the spindle speed programmed to 6k. It took a while to figure this out but once I did I figured it was because the spindle was getting due for a rebuild. I finally rebuilt the spindle last year and got a reader/ Digital Operator to change inverter programming so I was able to increase the spindle speed. It runs fairly fine up to 10k and will run up to 15k sometimes without alarming but 10k and above if you change the speed down with the override knob it immediately alarms out. Below are my notes when I ran the motor with it on the machine but not attached to the spindle.
Ran spindle motor without the coupling attached up to 15k from 7500 using the override. While it was not silent the bearings don't sound too bad.
Load at 15k fluctuated between 16-24%. When I dropped it down to 90% with the override it alarmed out. Here is the list of alarms:
3421 : (11) Inverter Unit Alarm (S1)
3395 : (10) Converter Alarm (S1)
3404 : (F4) Converter Alarm (A)
3403 : (F4) Converter Alarm (Z)
3402 : (F4) Converter Alarm (Y)
3401 : (F4) Converter Alarm (X)
3201 : Servo Alarm (S1)
3104 : Servo Alarm (A)
3103 : Servo Alarm (Z)
3102 : Servo Alarm (Y)
3101 : Servo Alarm (X)
3100 : Servo Alarm
3000 : Servo Off
Electronics are not my strong point but I do know enough not to cause more problems and would prefer to figure it out with your help. If not then it is time to find a tech to diagnose it, but I am about 1hr from the eastern edge of Portland OR so travel will be a significant part of the bill, especially since the only tech I know is on the southwest edge of Portland.
Any help is most appreciated.
