It works out of the box, but is a little underpowered, and anything past 15.00hz and the motor starts to squeal.

(Note: fixed this by increasing the carrier frequency to 110).

A few other queries - I see it exposes P+ and PB for breaking. I had hoped these could be used for access to the high power DC bus, but it only puts out ~10v DC so I doubt it. Wondered if there were any Chinese VFDs that would expose this bus, allowing parallel operation or DC only input.

Also, I noted it has an RJ45 port - but can see no reference to this in the manual, nothing about its purpose, default IP address, Modbus port etc. Am wondering if it is for a custom HMI and not Ethernet?

Thanks

 

Your adjustment to 110 Hz carrier frequency addresses motor squeal but may increase VFD heat. Monitor the VFD temperature, and consider adding cooling if needed.
