So I'm sure this has been posted about before. In doing my research, I referenced a few pages here. But nowhere was I able to find any one list that had both all of the right settings, and was free of mistakes. Now I'm no expert, but I do have a good understanding of electronics. I also understand that the things I DO NOT KNOW, I am not going to post my opinion of where I "think" that setting should be.

The way this came about was that I ordered and received one of the cheap E-bay air cooled 2.2kw spindles and VFD combo. Now sure, it came with instructions. And I'm betting if I would have followed them, and changed those 4 (literally, just 4) settings that the spindle would have ran. For how long, and how well...who knows. I have heard plenty of horror stories about these, but also heard of lots of guys running them for years (and still) with no problems. So I had to get to the bottom of it. Just because this combo is cheap...well..it is still a real spindle, and a real vfd, and I really wanted to get it set up working properly with at least on/off control in Mach3.

Success! Here's how I did it:

If you search the web, you can find many lists for the settings on the Huanyang VFD. A lot of them are for water cooled spindles, or 1.5kw air cooled. As you'll see, we'll cover these as well, but I wanted to be sure that I had everything right for the 2.2KW.

I figure the easiest way to start this is from the manual. Yes, the English is terribly broken in spots, but, it still gives us access to all of the settings and what they are. Here's a copy:

So, let's take this right from the start.

Step 1.) Un-Box your VFD and take the 2 screws out of the front cover. This will give you access to all of the spade terminals inside. You will see that along the bottom there is a row, labeled "R,S,T," on the left hand side and "U,V,W" on the right side. These are the only terminals we need be concerned with IN THAT ROW. The two rows above this we will get to later. So, your 220V power is going to have 2 live lines and a neutral. Usually Red, Black, and white respectively. We only need the 2 live lines. One goes to "R", and the other goes to "T". Supposedly you can also hook them to s and t, or r and s, but in every instructional video I found where people actually had the VFD working correctly, and it had lasted them a while, they were all hooked up one live to "R" and one live to "T". Ok, Now your VFD has power. I put one leg through a switch, so that the fan doesn't sit there running constantly. No reason for the VFD to be on when I'm not even in the shop.

Step 2.) The settings. Now that our VFD has power, we need to go through and set all of the settings to the proper place for our 2.2KW spindle (I'll show others as well)
There's conflicting info on the web about what order you do this in. So I tried it a few different ways. Makes no difference. Since the Huanyang automatically goes to the next setting after your done setting the previous one, I figure it's easiest to go in order.

To start setting press the "pgm" button. You will see a code displayed, "PD000". From here you can use the arrow keys up and down to change the PD number. You can also use the >> button to change where the cursor is. For example if the cursor is all the way to the right, then pressing up takes us from PD000 to PD001. But if I move the cursor over to the first zero, then pressing up would take us from PD000 to PD100. Once you're at PD000, press the "SET" button. Now we're inside of that setting and able to change it. After we get it where we want it, we press "SET" on more time, and that setting is changed. If the setting was already correct, nothing happens. If you have changed it, you will see "END" flash across the screen. Either way, now you can go on to the next PD number and the next setting.

So, let's go through them one at a time. Hopefully this will help someone like it helped me. I am listing all the ones that are required to get your spindle running properly, as well as all of the meanings that I am aware of.

PD000- Parameter lock-- 0 is unlocked, 1 is locked. So after you're done, you can come back to this and set it to "1" so that you don't inadvertently change anything.
PD001- Source of run commands-- Where the VFD gets it's command to start your spindle. 0 is from the keypad. 1 is from an outboard source such as mach 3 throwing a relay. 2 is from a data line (rs-485). Set this to 0 for setting up your VFD, and later you can change it to 1 if you're using a relay to control on/off like I am.
PD002- Source of operating frequency (spindle speed)-- Same as PD001. Set to 0 for now, and come back later if you're using speed control of some sort.
PD003-005- Main, Base, and Max frequency-- All of these should be set to 400Hz for any of the Chinese spindles. Mine already were, but a lot of the time these come factory set at 50hz.
PD006- Intermediate Frequency-- This should be set to 3.0 for those of us with 60Hz Mains power. If your mains power is 50Hz, set it to 2.5
PD007- Min Frequency-- set this at 1.2
PD008- Max Voltage-- Set this at whatever voltage is listed on your spindle itself. Mine was 220V, and yours most likely is as well
PD009- Intermediate Voltage-- Set this at 15
PD010- Min Voltage-- Set this at 8
PD011- Frequency lower limit-- Set this to 133HZ for 2.2KW spindles that are air cooled (this keeps RPM always AT LEAST 8k, for the internal fan). If you have a water cooled spindle, you can set this wherever you like, although you will get very little torque under 6k RPM anyhow.
PD013- Reset-- A Lot of posts say to reset this first? I wouldn't. A lot of my settings were already correct, why erase them and then have to re-enter. Maybe it's useful if you completely change spindles or change to a motor.
PD014- Acceleration Time 1-- There are other acceleration parameters as well, but this one affected the spindles acceleration. I set mine to 5 Seconds. You can set it to taste, but the faster you try to accelerate, the more strain in the system. 5 seconds in plenty fast enough to get to 24,000RPM!
PD015- Deceleration time 1-- Again, this one affects the spindles slowing down. I set mine to 7 seconds, and it stops very nicely.
PD072- Higher Analog Frequency-- Make sure this is set to 400hz for all the spindles.
PD142- Rated Motor Current-- Set this to your motors rated current. My 2.2KW air cooled is 8.5A.
PD143- Motor Pole #- According to the manufacturer, almost ALL of the 2.2KW spindles (as well as the 1.5 for that matter) are 2 Pole. So set this at 2.
PD144- Rated motor Revolutions-- This is how many times the motor should rotate in one minute at 50Hz. For these spindles, that's 3000. Make sure to set this, or your display will be off.

That's it. Now you can press "PGM" again to get out of the programming mode.

Remember when we first started, there were those 3 terminals on the right hand side labeled "U, V, X"? Those hook up to your spindle, respectively. U goes to pin 1, v to pin 2, w to pin 3. Your pins should be labeled, on the back side where you solder the wires to them. Make sure you use shielded wire, if you can, and connect the shield to the "E" terminal on the VFD.

Hit the "RUN" button and you're up and going. Like I said, I know this has been posted here plenty of times before, but it seemed there was at least one small discrepancy every time I found a list. If anyone needs help hooking up relay control, or speed control, I'd be happy to help. Also there are a lot of posts on those subjects, and they are both fairly straightforward.

Really hope this helps someone. Enjoy.
