My friend bought a HuanYang VFD, single phase 220V input to 3-phase 230V output to run a 5 HP motor, on his awesome (we hope) Zefam jointer. I have it wired and powered up, programmed the VFD after watching a couple of YouTube videos and studying the manual, such as it is. I have gotten the motor to try to start, but it trips out during acceleration and never comes up to full speed. When that happens I get an error message that says it's over current during ramp up. Most times I get that same message and the motor doesn't move at all. I've contacted the motor manufacturer TechTop and they have confirmed the motor is compatible with a VFD. I've tried to contact the HuanYang seller but haven't heard back yet.
I've input all the parameters outlined in the YouTube videos I've watched, the obvious stuff like motor volts, amps, rpm, poles, but the motor doesn't run so it must be something else. There is a parameter for Motor No-Load Current and the factory default is 40. There is no LRA listed on the motor plate, but there is a KVA code J, from which I calculated the LRA as 94 amps. Should I replace the NO-Load Current value of 40 with 94? That could explain the over current error message I keep getting. But what I know about this you can put in a thimble so that's why I'm here.
I have double checked the internal motor wiring and it's correct.
Does anyone have experience with HuanYang VFD's? I'd sure appreciate some help. Thanks.
