If you have a three-phase 110V asynchronous motor, this VFD can only be used with this VFD. Don’t use an external resistor (if need pls contact the seller for customization before purchase). Fan runs even when the motor stops. You need to change the Hertz parameter of the VFD if your motor runs at 50 or 60 Hz.
Before you buy a vfd, all of its parameters are set. You only need to change the Hertz settings to match your motor to connect it to use (The VFD defaults is 400 Hz.
A single phase or three phase 110V can be put in. This means that the output will be 3phase 110v. Frequency：0-50hz/60hz. 0-400hz.
If you don’t know how to drive a VFD, be sure to read the instructions before operating a VFD.

It’s a very good VFD controller, but the number of settings you can change is impressive and a little intimidating. My favorite thing about this is that I can set exact values for the maximum voltage and current, as well as how long it will take to get to the speed I want. The latter means that you can drive very heavy motors and other devices that would overload the controller right away if you used the front control knob to change the speed. It also stops the motor from speeding up too quickly while you adjust the speed with the front control knob.
Having voltage and current consumption on the screen would be very useful because it only shows one value at a time.
For the record, I’m using this controller to run a 24V turbomolecular pump with this controller, which is why I’m telling you this. Without a very slow start-up or a lot of power it goes over the current limit. This controller works very well with the right parameters set up.
