How to Size, Wire, and Program a VFD to Convert Single Phase Power Into 3 Phase Power

In this video, I discuss how to use a variable frequency drive (or VFD) to convert single-phase power into three-phase power. I cover some important things to consider before starting your project that will help you avoid a mistake that I made. (These are applicable regardless of the brand of drive you use.) I also show you how I wired everything up and programmed my Huanyang “HY” series VFD. Trying to decipher the instruction manual that it came with was a challenge. I had to watch a lot of YouTube videos and confer with some of the electrical professionals where I work to get it figured out. So, I wanted to make this video to share what I’ve learned to help others who are trying to do the same thing.

Setting up an Ebay VFD(Haunyang HYD02D223B) with an external switch and an external potentiometer.

To calculate what size drive you will need, multiply the amp rating of your motor times 1.73. The proper drive should be able to output this much current or more. Check out this link for a more in-depth explanation.

The programming instructions and parameter values listed below should be compatible with any of the following HY Series drives from Huanyang: HY00D423B, HY0D7523B, HY01D523B, HY02D223B, HY03D023B, HY04D023B, HY05D523B, HY07D523B, HY001123B

Steps for programming the parameters.

1) Press “Program”
2) Press “Up” or “Down” arrows to get to the parameter you want.
3) Press “Set” to select the parameter for editing.
4) Press “Up” or “Down” arrows to enter the setting you want.
5) Press “Set” to lock in the new parameter value.

*Note: The “Shift” button changes the input position from right to left across the display.

Parameter My Explanation
Value

PD000 0 0 = Allows VFD parameters to be adjusted
1 = Prevents VFD parameters from being adjusted

PD013 0 8 = Reset VFD to factory settings

PD001 1 0 = Start/Stop motor by buttons on the front of the drive.
1 = Start/Stop motor by external switch
2 = Start/Stop motor by computer communication port"

PD002 0 0 = Motor Speed adjusted by buttons on the front of the drive
1 = Motor Speed adjusted by potentiometer (Onboard or external,
jumper on “VI” for external or “VR” for onboard)
2 = Motor Speed adjusted via computer communication port"

PD005 60 The maximum frequency that the drive will send to the motor.

PD004 60 Rated frequency of the motor as listed on the motor's nameplate.

PD003 60 The frequency (speed) the motor starts off at when PD002 is set
to 0.

PD008 208 Rated voltage of the motor as listed on the motor's nameplate.

PD014 2.0 Time in seconds for motor to accelerate to full speed.

PD015 2.0 Time in seconds for motor to decelerate to complete stop.

PD023 1 0 = Reverse motor rotation not allowed.
1 = Reverse motor rotation is allowed.

PD141 208 Rated voltage of the motor as listed on the motor's nameplate.

PD142 6.5 Full load amp rating of the motor as listed on the motor's
nameplate.

PD143 4 Number of poles = 120(f)/n where f = motor's rated operating
frequency (60Hz in the USA) and n = motor's rated RPM on the
nameplate.

PD144 1700 Rated RPM of the motor as listed on the motor's nameplate.

Congratulations you are the first person I have found that explains how to programme one of these inverters to run using a standard motor rather than a spindle variety. Thank you ever so much!

Thanks for the video, I was able to get a 3-phase jump saw working using the 5HP HY VFD. I was even able to wire up the old momentary start/stop switches and emergency stop by programming the three communication ports to correspond to the Run, Stop, and Emergency commands. What's great is the VFD will be able to function with either an "NO" or "NC" momentary switch, and it works the same with either style. The saw was previously in a 460v factory directly wired to the industrial 3-phase supply, so instead I re-wired the motor to the low voltage 230v configuration and hooked the motor directly up to the VFD, bypassing the old relay and fuse setup that the saw came with. The VFDs are really awesome, having all the switching built into the unit is great, but it's even better that it has the com ports that are programmable to like 30 different functions you can control with external switches. In my case I only needed start/stop/emergency because it's just a jump saw. I did set my PD014/15 acceleration time to 10s because the saw blade is 14" and I'm hoping the longer time is easier on the motor and belt.

By the way, to anybody wondering if they can power a 230v motor when the documentation says the VFD is 220v, you certainly can! Just make sure you set your Pd008 to 230, and make sure that your input voltage is 230v or higher on the lines as measured at the VFD, because the VFD can't step up your voltage, but it can transform down if it needs to, for example if you have 240v at your panel like I did. Also, I used stranded copper 14AWG for the communication wires which may have been overkill but they did fit well, and I used solid copper 10AWG for the power supply and motor supply wires, which were a tight fit. Granted my motor is only rated for 12A, but 10AWG is what I had on hand and it worked.

This video is thorough and well done. I appreciate the indexing and VFD programming chart!

[paulgreenlee]

Southern Genius to figure out all the codes. I have a VFD and it's the same model you explained. It drove me crazy trying to figure it out. I watched this video, and the gray area came together for me. I'm running my 1960 13" South Bend Lathe on this VFD. I need to wire in the switch now that you explained it. I appreciate what you did to put this together and you did a great job explaining it. I agree that it was done very professionally, thank you. Nothing better than living in the South.

You don’t know how long I’ve been looking for this video, I’ve became a homegrown DevOps engineer all because of a couple of questions I just couldn’t answer myself. One of those questions was… which way to I face a 2-phase to 3-phase converter? Although it sounds obvious now. I could have used you about 2 years ago!

[brucewilliams]

You did a great job on this video. Thank you for all the hard work in putting this together. Professional and slick.

[MikeB]

Really appreciate you taking the time to put out this video. Just bought one of these after my very simple Baldor VFD shit the bed on my 1966 Bport after 25 years. Tried deciphering the manual till my head was ready to explode. Gonna finish wiring it up tonight and follow your steps in programming and hope I don't let the smoke out! Tks again.

[thebunnyman]

I was about ready to throw it against the wall, so happy I found this video. You rock.

[brianguest]

man you helped me greatly i added a much larger lathe 25x80 and was about to upgrade my phase converter that i built when I watch this video I decided to purchase a huanyang GT 20HP first one arrived beat to crap thank you delivery company emailed company and they had a new one in 4 days they said 4 days and unlike most company's they kept their word hooked it up codes are different than yours but it is awesome from one Southern Boy to another Thanks alot

FYI - They do in-fact sell drives that can step up voltage. I'm currently programming a HE100-T3S-7R5G and it is 1ph 220V Input and 17A 3ph 380V -Great video tho, lot of helpful info.

[ryanmctee]

Thank you so much for such a step by step video. Excellent information.

[jdmyers]

Very helpful, thanks for posting this for those who are not familiar with this process!

[GuntersGarage]

Hey, your info was key to programing my HY inverter. I have the same mill and model inverter so it was easy as jotting the parameters down and run out to the machine to punch them in. It was literally running in minutes. Thank you so much!!

[daveg]

Very good video. It explains the connections to and the programming of the VFD very well. The manual might as well have been written in Swaheli.

[hawkbox]

This is an excellent video, I'm trying to replace a fried VFD on our power hammer motor and reading the manual was painful. This gives me something to work on this weekend.

[ronwalsh]

So glad I found this video. I found a couple of WWII motors that are 3 phase at 110v. I was a bit concerned that I would not be able to run them (not sure what I am going to use them for, but they were cheap). I may set one up as a belt sander motor.

[BenjaminGatzke]

Excellent content, pace, level of detail. Went through a lot of videos to get to this one! Thanks!

[Warriorable]

Already this video is incredibly helpful!!! Thank you so much. Not too many ppl on the west coast have info or knowledge on phase conversion or powering manual mills. 🙏🙏🙏

[TimmyFannin]

Great video sir! I seen a Bridgeport on marketplace for cheap and had to have it. Its still wired for high voltage from who knows when and where but I'm going to give it a go! Thanks for clearing up the process!

[IHFarmer]

Awesome video, showed exactly how to do what I was wanting to do with very good explanations!
Thank you!
