Review on 🔄 Enhanced Variable Frequency Inverter Converter by Viswanath Lopez

The description of this VFD is correct even though the model sticker doesn't say it can be run on 1 phase. There is also no mention of 1PH wiring to this device. The VFD was connected to 240v 1 phase and it worked great with a 2.2kw 220v 400hz spindle motor. I've connected it to R and S and also tried R and T connections and everything worked fine both ways. The translation from Chinese to English is pretty good in the included instructions. We hope to receive the PDF manual from MONSTECH. I got the PDF manual back and forth after a few posts. Stay away from this VFD if you ever need assistance, MONSTECH cannot help you. They just reply in gibberish. This VFD says it supports RD485, when trying to communicate with it via the RTU there are errors in the commands. This VFD does not use standard RTU commands. It was the answer I received when asking about RTU commands in HEX that caused me to change my overall rating to 1 star. A very disturbing reaction. Oh, and this VFD is not FCC approved for use in the US, another reason to stay away, its use is a violation of part 15 of the FCC rules and regulations.
