Review on 2KW MYSWEETY Variable Frequency Drive Converter VFD by Harley Franchetti

I am using this VFD on a 3HP/3 phase 60Hz/230V motor. I wired it up (easy). I skimmed through the included instructions, but they're pretty self-explanatory. Two hot feet in and out. Three exits and one common. Unit turned on and the potentiometer turns it from stop to factory setting 50Hz. Perfect up and down. Since I'm building a 2x72 belt sander, I need all the RPM my motor is rated for. 3450. I've tried following their instructions, their video posted on Revain, YT's video, numerous instructions on hobby forums and couldn't get this thing to go above 50Hz. I can connect things, I can weld, I can build. Pushing buttons and understanding computer things. no Luckily I contacted the seller via email and within 4 or 5 days they got me right. They responded to my numerous emails in a reasonable time and figured it out. For those who need it, the following parameters need to be changed. P00.00P00.04P00.05P03.09 The last one was my freeze. This tells the device the maximum power of the potentiometer. The VFD now outputs 75 Hz at full power. I am very happy. I haven't built my coffee grinder yet. There are some concerns on the grinder forums/FB pages about the durability of unsealed VFDs versus very $$$ KB units. I will use it openly instead of building an extra hull. It would be best if I added a few particle filters to the holes in the devices. I'm interested in the durability. I'll update this review if the VFD fails, or I'll try to update it if it continues to meet my expectations.
