Success! I reset unit to 50hz factory default as suggested, the as received default was 400hz. The motor ran. Then I proceeded to set one parameter at a time, testing the motor each time. The one that cause problems was the min. frequency, when set to 30hz, I got the Overcurrent on accelleration fault. Set to 10hz and it worked fine. Evedently the starting ramp up begins at this speed. I don't need to run at this speed as this is driving a paint booth fan and 1/2 speed is the lowest I should ever need. I must say, the Lenze unit I put on my Bridgeport was much easier to get working as I wished. In a fan application I didn't feel sensorless vector was needed so I tried the cheap approach. Thanks all for the advise.If this unit has only one row of low power connections and no built in pot, it's really an Askpower HY series. If so, set PN32=6 as a first step. This will give you a factory default for a 50hz motor rather than the 400hz spindle.
As a wise man in the Southbend forum once said. they had much bigger horses back then. If this is an old underrated 2HP motor rather than a new highly optimistic 2HP one, I suspect you under-bought. Either way, Askpower or Haunyang, give yourself a little headroom, especially if driving it from single phase. I have a 1HP Cincy mill and a 1.5HP SB lathe, both out of the mid 1950s. I put a 2.2Kw Askpower on each, and couldn't be happier.
