1. Huanyang Vfd Settings

Here are the VFD and motor labels. The Commissioning part of the manual is terrible for understanding what buttons to push. VFD = Huanyang HY02D223B Settings. Hi, can you share the manual, I can´t fond this specific HDMI manual VFD I found another HDMI manual and I.

How to setup Chinese VFD to 2.2KW spindle. Picture included, as well as PDF manual. (I dont own the product, just figured this would help EVERYone else out that does!!) PDF file is 15.8MB (large). It actually is very easy to read and navigate, i was impressed on how informational it is. Hope this helps someone! I drafed the wire picture. Please see from the link: 2.

You can see download the inverter manual from web link: 3. I just tell you how to set up VFD as following Firstly, adjust the PD013 to 8 (set the setting to factory setting) Secondly, adjust the PD005 to 400 Thirdly, adjust the PD004 to 400 Finally, adjust the PD003 to 400 Finally, adjust the PD144 to 3000 Note: you should set PD013, PD005, PD004,PD003, PD144 in order.

It mean you should firstly set PD013, then PD005, then PD004, then set PD003, finally set PD144. Note: after you set the all above parameter, then please recheck the PD005, PD004, PD003 value is 400 or not to confirmed that you already set it. (note: please do not check the PD013, or all the setting will go to factory setting) The reason we let you recheck is that if you do not set it at 400, then when you run the spindle motor, the spindle motor will be over-current, then the spindle will very hot and then within 5 minutes, it will broken.

I got my 1.5 water cooled + VFD about a month ago for 250 bucks.including shipping. I could not be happier.

Took me a bit to get the VFD set up, but with all the threads here dealing with them it was easy to find the right settings. This thing out performs the trim routers I have had on my 24x24 by miles. I have gone threw 2 routers and countless bits due to lack of control over spindle speeds in the last year. I am just a 'Home Hobbyist', and do a little custom work on the side. So my CnC is lucky if it runs 20 hours a week. And if this lasts a year for me, it will more than paid for itself.

Ken The spindle seems solid, and the VFD seems to be a vast improvement over 'older' models. Thank you for the information about setting things in the right order. I have one of these Huanyang 2.2KW VFDs as well and so far it's not working. Not sure if its me or maybe a bad drive(?) I connected to a single phase 220VAC (which measures 245V). When applying power, after a few seconds I get 'LV' displayed. The manual indicated this is 'low voltage' and that I should check the input voltage, change in load, or missing phase. After messing around with this myself and then resetting to defaults, I set the parameters as described above but no change.

Huanyang Vfd Settings

Has anyone seen this behavior or know what I need to do?

Hello All; I purchased a used lathe and it came with a 3-HP 3-Phase motor. I live in Thailand and the power here is 220 Volt 50Hz. The motor had been set up to run 380 Volts 3-Phase and try as I could I could not find anyone here to switch the motor back to 220 Volts 3-Phase as the plate from the motor was missing. So what I had to do was to Purchase a VFD that was capable of taking in 220 Volts AC and then changing it to 380 volts 3-Phase. I checked with several people and I was advise to purchase this model Huanyang GT Series Inverter Model #HY04D23B-T. I have now wired up the inverter to the lathe and have tried to set up the parameters so the unit will run in its basic mode by using the front panel of the VFD.

However I cannot get the unit to start the motor as something is wrong or most likely I have not set up the VFD correctly. I am including information on the motor as well as images I took from the VFD and the user’s manual. If someone could please walk me through the set up slowly it would be greatly appreciated. My Motor: The motor is a Mitsubishi Superline motor and is listed as being from Japan, I think. It says: Three Phase Induction Motor.

3HP 4 Pole Type SB-E JIS C 4004 Frame 100L Hertz 50 Rotor C Voltage 220/ 380 Ins. Class E AMP 8.7 / 5.0 Rating Con RPM 1420 Amb. Temp 40Degrees C Code H Weight 28Kg.

Bearing 6206ZZ & 3205ZZ Here are images of the VFD and Manual that I hope might help you in getting me started? I will be happy to provide any other information that you might require to get this unit running! Best Regards Al. I have the very same 3HP unit. I know the manual makes you feel upside down a tad!

Did that (a lot) - Do you plan to wire this into any existing frwd/ and rev. Controls later? Any Interlocks and obvious safegaurds via limits you may need to input to the VFD to stop the motor? Had a really good post recently on this w/ a Schematic and lots of good info. Search the Forum for VFD lathe and Dawson. As for your Codes - I think I have mine all written down in the book. Do you have a list of the ones you changed or set?

Let me know if you want me to post back my codes. When you power up the unit, what do you get on the display initially? And then you press RUN and what happens? I have the very same 3HP unit.

Thank you for the quick reply and assurance that others have been in the situation that I am in, this is driving me crazy and my wife is all over me for not getting the lathe working after spending so much money on it.

Regarding your question about what I want to set up when complete, I want only to configure a remote On/Off switch on the lathe. The lathe has good speed control and reversing capabilities already so I want to keep this conversion very simple. I hope you follow my thinking. The codes that I have changed or confirmed are as follows: P2.01 (Power)??? P2.02 (Frequency) 50 Hz. P2.03 (Speed) 1420 RPM P2.04 (Voltage) 380 Volts P2.05 (Current) 5 Amps I do not know the following: P2.06 Motor Stator Resistance? P2.07 Motor Rotor Resistance?

P2.08 Motor Stator and Rotor inductance? P2.09 Motor Stator and Rotor mutual inductance? P2.010 Motor current without load?

I am not sure what is meant by the Note: The motor should be de-coupled from the load; otherwise the parameters obtained by auto tune may be incorrect. Regarding the settings P0.02 P0.03 P0.04 P0.05 P0.06 P0.07 P0.08 etc. I am not sure what I put in I did my best based on what I know and what I thought the manual was saying! Thank you Al. I have the very same 3HP unit. I know the manual makes you feel upside down a tad! Did that (a lot) - Do you plan to wire this into any existing frwd/ and rev.

FONT=&I am not aware of current VFDs being able to generate a voltage higher than their input voltage. The diagram you show, shows 380V 3 phase in to get adjustable 380V 3 phase out, but the manual is pretty generic.

I could not find any information listed for this model/FONT. I believe based on the nameplate nomenclature the correct model number is HY04D023B. The B-T might be some new step-up converter version, but I would contact the seller as to how this is done/programmed. It could be your set-up parameters are wrong, or source of the run commands are not correct. I have not used this brand of VFDs, but here are some programing parameters you might review below.

See if you can get it running first (even on lower output voltage), then we can fine tune the parameters. I would also read the manual for other VFDs, they often give a better description of the parameters and effect. Model～ HY 04D0 23 B Inverter Capacity, 04D0 means 4KW Voltage Rating, 23 means 1-phase 220V Software Version B There is nothing related to your model number in the manual, but all the ones listed with the 23 in their model number are Single & Three Phase 220V 50Hz. All the ones listed with 43 in their model number are 3Φ380V 50Hz TABLE='class: MsoNormalTable' TR TD.

Hello All; I have went though all of the parameters many, many times and they are set to the best of my knowledge/ability. I tried to cross reference to what 'mksj' said but there are differences. OK let me tell you where I am at, the VFD seems to be putting out approx. 325volts of 3-Phase power and the motor is now running.

I connected it up to lathe and it started but shortly there after it shut down with an error message. I reset the VFD and changed the transmission on the lathe to a higher speed it ran longer then shut down. I set the transmission on the highest speed gearing and the lathe ran fine. I am not sure where the problem is but it seems to me the issue is in the amperage being given out. The voltage is not at the 380 Volts like I specified but that is not a major issue as the lathe is running at the output voltage and I am happy with that! If it helps I am prepared to scan many of the pages in my manual for those that understand VFD's.

I am determined to make this work! I ask you please to stay with me on this issue as my wife is now furious with me for buying the lathe! Thanks to all! Hard to say about measuring the output voltage with a conventional Multimeter, since the waveform is PWM (but you do have voltage).

I use a Fluke 289 which has filtering and gives more accurate readings. Depending on the meter's bandwidth, a conventional DMM can give measurement voltages 20-30% higher than actual. It would seem that your output voltage is lower than expected, I would check the VFD output w/wo the motor running and what happens when the motor trips.

It might be tripping the converter because of a low bus voltage or under current. There should be an error code listed when it trips, which tells you why this occurred. Hopefully someone can tell you what the error code means, as I see no explanations in the manual. Regarding the programming nomenclature, usually these are listed in groupings of parameters, like pages in a book. So in this case P0 is PD which are basic parameters, P2 looks like motor parameters, but once again this is specific to each VFD. I would not assume they are the same nor in the same code. Per Jim's posting, make sure: PD008 = 380 PD009 = 27.5 PD010 = 13.5 The motor should be configurable for 220V 3 phase per the motor description.

Thank you mksj and Jim Dawson for hanging in there with me, it is much appreciated! You are correct it looks like the P0 parameters similar to the PD parameters that you have but they seem to be more extensive. With the P2 parameters they are the motor parameters!

The best thing for me is to start off I think with the P0 parameters then we can move on to some of the remaining parameters, OK! P0.00 Speed Control model (Values 0-2) P0.01 Run Command Source (Values 0-2) P0.02 Keypad and Terminal Setting (Values 0-3) P0.03 Max.

Sorry gang- I was busy w/ Firewood most of the day! On the start up - Tell the Misses it just takes a bit of time but it'll all work out. This should work and it's a very sophisticated device.

I've been nearly in fits and tears at times. Tell her one of my Fav. Quote scenarios: 'Experience is a tough teacher. You get the test first, and the lessons later'. I've started to get things together pretty well as time has gone on.

A few things: #1 can we revisit your Motors input VAc setting? Is it possibly wired for 220 -vs- 380? This is usually something you setup w/ jumper bars under the lid where the wires go in. A jumper Config for 220 3 phase input or a jumper config for the 380 3 phase. I am wondering is this is set to the 220 3phase under the motor's hood. Which would lead us to swap around your settings back on a few PD values. Or was that already confirmed in the threads?

If set wrong the Current and Voltage curves will be all off and it will pop the error codes and stop. The 4 poles note is also important. The Poles setting is found on page 54 PD143. Should be 4 (default) And maybe check these too pls.

PD141 rated motor Vac. (when you find out if 220 or 380 hard wired for the input ) PD142 rated current of motor PD144 Motor RPMS PD14 can slowly be increased for torque. Default of 2% but goto 3, 4, or even 5% (After you determine what the motor is wired for). On the bottom of page 28 of my manual, there is a small chart which outlines some code defaults for P009,10,14,15,41 Your model is on the top line. Sorry gang- I was busy w/ Firewood most of the day!

Hello countryguy; OK regarding the motor the owner of the shop confirmed today that the Voltage that the motor was set at was in fact 380 Volts. Before ordering the VFD I took the motor to a small company who rebuilds motors and had asked them to switch it back to 220 Volts. Living here in Thailand can be difficult basically a language difference.

In his mind I think he thought that strange as 3-Phase power here is only 380 volts. I tried to explain that I wanted to install a box that does 3-Phase conversion but he could not grasp the concept. He plugged my motor into a 3-Phase receptical and it ran fine. I went to his business this morning and he confirmed that the 3-Phase that he gets is 380 Volts. So two people have confirmed that the motor runs at 380 volts.

I could not find a setting whereby one sets the number of Poles. I sound a section at the back of the manual that lists all of the segments that can be set. The range is P0.xxx to P9.xxx then to PA.xxx, Pb.xxx and PC.xxx. This shortened version of the codes and what they are makes up approx.

Not something I want to scan. I will after completing this reply provide an more detailed description of the Code Groups and what they mean. If someone can figure out which ones we need to concentrate on I will scan those pages and post them. Final note, my VFD is I believe a more complicated box versus the standard 220 Single Phase to 220 Volt 3-Phase that most people have. I wanted to go this route but due to the motor situation I decided to pay the extra money for the larger unit. My thinking that by doing this it would be trouble free, Boy was I wrong!

Best Regards Al. Hello All; I found at the back of the manual a condensed version of all of the code types supported by this VFD.

This condensed version covers approximately 33 pages which is a bit much so what I have done is broke each segment into what function that segment covers. If you want details on a particular function I can the scan that portion and post it here. The functions and what they cover are: P0.xxx Group Basic Functions P1.xxx Group Start and Stop Control P2.xxx Group Motor Parameters P3.xxx Group Vector Control P4.xxx Group V/F control P5.xxx Group Input Terminals P6.xxx Group Output Terminals P7.xxx Group Human Machine Interface P8.xxx Group Enhanced Functions P9.xxx PID Control PA.xxx Group Simple PLC Pb.xxx Group Protection Function PC.xxx Group Serial Command I hope this helps so we can get this VFD running my motor.

Please note there are 127 pages in this manual and most of it is a challange to wrap ones mind around! Here is my take on what's going on: You have been talked into or duped to buy a GT series VFD, which is a vector control VFD (that means it measures what's going on with the load on the motor and compensates to maintain speed no matter what the load). That is an excellent VFD, but does not address the issue of voltage increase. The label is pure fiction, I believe, and probably a translation mistake or two. It says that it's a 2-phase 220V input. There are 'two-phase' electricity supplies in some parts of the world, but usually 440 or 480V.

The circled connections in your manual indicate however that it is suitable for single phase or three phase supply connections. In any case, the output voltage will be whatever the input voltage is - plus or minus maybe 15% depending on the parameter settings. Maybe that's why you were able to measure more than your input voltage. Could you please tell us at what output frequency you were measuring the output voltage? Also, this is a 5Hp VFD (4kW), so you will HAVE TO set the parameter for the maximum lathe motor current or the VFD can cook your motor! But back to the voltage thing: Please photograph and post the insides of your motor's terminal box - both the connections AND the inside of the cover.

Usually, the connection diagram is on inside of the cover. If not, I'm almost certain I can tell you and show you how to connect it for 220V. It's generally pretty simple, even without a diagram. The GT model may have some different parameters to the normal vectorless models that many of us have (because they are a lot cheaper), and there will be parameters related to the VFD behaviour on changing loads. So we need to be careful when we make suggestions to you as to which paramters to change!

Lastly, this VFD can auto-tune and set many parameters to the correct values itself. The instruction you read to 'decouple' the motor to do this means you take the belt off the lathe, so the motor can run without driving anything.

That way the VFD can measure the free-running (no-load) current, the no-load slip, the no-load design speed and probably the coil impedence without slip while running. It will use those values to determine a response to varying loads. So let's go from here and set your motor to 220V DELTA mode - from 380V Y or 'Star' mode. Then you can reset the VFD to factory values (the manual will tell you how) and we'll go from there. This VFD and motor will be able to some really fancy things - like emergency braking in a split second, normal 'spinning down', reversing under full power (think 'rigid tapping' and threading), have variable automatic limits set and things like that. Trouble is, once you have had a vector control VFD you will think of any other type as 'seriously deficient' PS: I note the the seller offered to email you an ENglish manual.

Did you take him up on that and got it? If not, please ask him for it to be emailed to you!

It will be terrible English, but I got quite fluent in 'Chinglish' about VFD's recently (bought some used VFDs from China that had no English documentation and used on-line and Microsoft translations only.). Cheers, Joe (at last count I have 9 VFDs running, 3 of them Huanyang ones, first one over 20 years ago. When they cost as much as a used car - it's still running by the way, none of my used cars from back then are.). Good Morning All; Yes it is a very good morning, last night I decoded to set the VFD back to factory specifications, this I did.

I then pressed the start button on the VFD and the motor started with out any problems that I have been having. I tried this several times and in each and every case the VFD worked flawlessly. I then connected the two drive belts to the motor which would then drive the lathe and tried the start button again, here again the motor started well in every speed range of the lathe. I checked out the quick change transmission both in the screw cutting and power feed functions and it worked very well. Today I want to change two parameters and that is the Acceleration and deceleration time variables. After that I want to go into the factory setting and check what they are set at however, I expect to leave well enough alone.

This process has been a very painful one for me over that past week or so and it has made me really appreciate the value of having the support of the many good people her who have gone out of their way to try and assist a fellow member and for that I am very grateful. Thank you all! My next step will be in wiring up a basic On/Off switch that I can mount on the lathe to make live so much easier. In addition I am now considering wiring up a speed controller on the lathe, I originally though about not doing this but there is a benefit to doing this versus changing the transmission on the lathe. This will entail a new adventure for me but I am sure with your assistance this will work out fine. I believe that I have to connect wiring from the switches to the 'Control Circuit Terminals' and the change one or two functions on the VFD to support remote operations.

Thank you everyone again for helping me out it is very much appreciated. Best Regards Al.

Thank you everyone again for helping me out it is very much appreciated. Best Regards Al. Hello, yes it would have been nice to know what specifications where causing the problems. I went through the major setting this morning and recorded there values so I could compare with values I used here are some of the values that where changed by the reset.

P0.14 Carrier Frequency Default 5.0 My choice 15 P2.01 Motor Rated Power Default 5.0 My Choice??? In addition there was a list of motor specification that I did not know and thus guessed or left blank. Examples are Motor Stator Resistance, Motor Rotor Resistance, Motor Leakage Inductance, Motor Mutual Inductance, etc.

I have now adjusted the ramp up and down time to three seconds and it works well. I want to Install an On/Off switch on the lathe to control the VFD what parameters do I need to set on the VFD and what is the designation of the terminal points on the accessories block? Here is an image of the Box I purchased: When that is complete I want to add a 10K Pot to the lathe for speed control. Best Regards Al.

FONT=& You mentioned that the manual may be available electronically, it would be great if you could download and post in this forum. The scans are difficult to read. The ON/OFF switch is for power going to the VFD would be fine, make sure it has a sufficient rating for this VFD (probably want a 25A or 30A), you also should have some breaker or fusing (30A).

The VFD motor terminals are wired directly to the motor./FONT FONT=&Review Page 28 on in your manual. Also in the back of the manual, there usually is a tabular listing of all the commands and options (like a short form). I often print this out and make notations on that when I do my programing.

I would recommend making one program change at a time, and then testing the change to make sure it is working correctly. This can be done via a USB cable on some VFDs, which greatly speeds up the process./FONT FONT=&P0.00 - On a lathe I would run Sensorless Vector control, which will give you more low end torque. Looks like a setting of 1 would be the most appropriate./FONT FONT=&P0.01 - Is for running external controls (run command source).

You would want 1 for external terminals if they are connected/FONT FONT=&P0.07 - Is the Frequency command source, setting to 1 specifies a speed terminal voltage source (A1) to a pot/FONT FONT=&In order to use the input and speed terminals, you need to have your controls rewired and add a speed pot. An example is attached.

You pretty much gut the contactors and transformer, and use a VDC single 4 pole relay in the provided example. The voltage of the relay must be the same as the VFD control bus voltage (the total load for the bus is usually around 100-200mA). On some this is 24VDC (P24), others it is 12VDC. Another option that I commonly use is to use a small PWM universal power supply, something like a Mean Well (NES 15-24) 24VDC 15W, a main power relay and a for/rev relay.

I can post an example if interested. You always want to make sure that you have an E-Stop that kills all commands and that with a power glitch, that the machine will not resume operation until a power reset./FONT There is also an E-stop command that can be programmed to a terminal, but in this model I believe shuts down the VFD output to the motor, so there is no braking action on deceleration.
