Askpower VFD looks like a chinese knockoff of a chinese huanyang VFD from the outside but the setup parameters are different so any info I found on the Huanyang doesn't help. I think unit may be defective but wanted to ask here in case I'm missing something. There aren't that many variables that can be changed on these units so it SHOULD be pretty straight forward.
Unit is a 2.2kw 240v single phase in to 240 3 phase out. Verified 240v single phase input, but I'm not getting the 240 3 phase output. At 60hz output on VFD I'm only getting 20v between any pair of 3 phase outputs. I played with max frequency setting and remeasured output voltage.
40hz=10 volts
60hz=20 volts
120hz=53 volts
240hz=117 volts
400hz=190 volts
I have: Pn02 (initial startup freq) set to 60hz; Pn10 (max runtime freq) set to 60hz; Pn11 (min runtime freq) set to 1.5hz; Pn12 (motor rating) set to 60hz
When max runtime frequency is set to 60hz, I know voltage goes down when frequency is decreased, but when run at the max setting (60hz) I should be seeing 240v.
Anyone have experience with these units and think it sounds like I have something setup wrong. Or does it sound more like a defective unit?
