Hi,
I just received this sensorless vector VFD: HUANYANG Vector Control Drive SL series SL 222EE 2.2KW 220V 3HP VFD inverters 2200watt frequency converters spindle inverter-in Inverters & Converters from Electrical Equipment & Supplies on Aliexpress.com (the link to the manual: http://www.soonwell.com/ebay_file/us...ter-Manual.pdf ) and I'm having problems setting it up correctly with my Chinese 2.2kw spindle.
First I tried to set it up for the sensorless vector mode.
After resetting to default settings I set the following settings:
P0.00 -> 0 (Sensorless vector control)
P0.01 -> 1 (trimpot as frequency command source)
P0.13 -> 400 (Maximum output frequency)
P0.14 -> 400 (Upper frequency limit)
P0.15 -> 120 (Lower frequency limit)
PB.02 -> 2.2 (Motor rated power)
PB.03 -> 400 (Motor rated frequency)
PB.04 -> 24000 (Motor rated speed(RPM))
PB.05 -> 220 (Motor rated voltage)
PB.06 ->10 (Motor rated current)
Then I ran autotuning (PB.00 -> 1)
After autotuning finishes I try to start it and it does 2-5 jerky turns and then stops. Changing speed (frequency) with keys or trimpot doesn't do anything.
Then I tried to configure it in the V/F mode.
After resetting to default settings again I set the following settings:
P0.00 -> 0 (V/F mode)
P0.01 -> 1 (trimpot as frequency command source)
P0.13 -> 400 (Maximum output frequency)
P0.14 -> 400 (Upper frequency limit)
P0.15 -> 120 (Lower frequency limit)
PB.02 -> 2.2 (Motor rated power)
PB.03 -> 400 (Motor rated frequency)
PB.04 -> 24000 (Motor rated speed(RPM))
PB.05 -> 220 (Motor rated voltage)
PB.06 ->10 (Motor rated current)
With these setting it works at maximum RPM (24000) but when I lower the speed with the trimpot it slows down and then the speed begins to oscillate slightly, current rises from 1.8A to ~7A and then the inverter trips with error OC3 (overcurrent when constant speed running).
Any help or advise will be greatly appreciated!
