I have a 1998 WoodFast M910 (Rikon 70-500) the inverter went out on (ABB300
) a couple of years ago. I scrounged E-Bay and found another for $400.  Ins
talled and it worked fine, until a few weeks ago.  I went looking for anoth
er inverter and found a Hitachi WJ200 that looked like it would fill the bi
ll.

Got the Hitachi, read the manual and realized I needed help.  Called Custom
er Support and was blown away.   I have NEVER found a CS that was so custom
er oriented.  I am not talking about "hold your hand and make you feel bett
er,." but is genuinely interested in getting your inverter set up correctly
 and answer ing any questions.

With the motor mounted where it is, reading the plate is difficult.  So cal
led Leeson and found they could give little information, because its a prop
rietary.  The could, however, tell me the number of poles (6) and the freq.
 (1144) .  

I have it up and running, but at about half way through the speed range, I  
start getting, what appears to be, a harmonic squeal.  I have two questions
:

      Is that indicative of something that will harm the motor, or inverter
?

      Can I continue to run it and just put up with the squeal?


Thanks

It turned out to be a parameter setting in the inverter.  Changed it and th
e squeal went away.
