Thread: Huanyang 7.5 kw VFD

I assume you tried turning it off, waiting a while and turning it back on again?

I did still nothing

I would do a factory reset - check the manual.

I would do a factory reset but I can't get into the settings. There must be a way to reboot on start up but I don't know how. Or to push certain buttons on the control panel in sequence.

http://www.jinlantrade.com/ebay/invertermanual.pdf

There are various mentions of reset in conjunction with various terminals ("terminal to be used after removing fault").

Considering how many control circuits work these days, my first try would be to hold down various keys and key combinations during powerup - say shift-stop, or shift-start-stop for 4 seconds or thereabouts and see if that triggers a flushing of non volatile memory and a factory reset. It might be worth having a look at the pcb to see if they have a flush/reset button hardwired as well.

Sounds to me like you have accidentally locked it with PD000 and or set it to exteranl commands with PD001
Since it is clearly set to external mode, connect a wire between DCM(COM) and RST (Multi-input3). The control voltage is 10V so you can screw one end of a short wire to DCM and just touch the other end to RST by hand. DON'T touch the larger power connectors below there! They will bite!
Then follow the manual to do the factory reset and start again.

Sounds like your familiar with this unit. I on the other hand am not. Im not sure what you mean by the RST(Multi-input3) Is the 10 volts being supplied by the fvd or I using an external 10V? . It sounds like just a jumper between the two terminals com and rst ( what ever that is.) are you able to tell by the picture of the drive I sent what you are referring to? Thank you for helping me with this matter.

Sorry, I thought I was reasonably obvious.
Have a look at the labels on the green connector block just above where the power goes in and the motor cables connect. They are labelled exactly like it shows in the manual on page 10 approximately in the middle, and the detailed description of those terminal on page 11. The 10V control power is provided inside the VFD. You don't have to do anything with that. I only mentioned it so you are not afraid to touch those connectors....
Do you have the manual? If not, download it from the link given to you by P.W.H. You WILL need to refer to it to set this up or modifiy settings down the track. You also need to understand what it tells you about the settings YOU want to change. All the factory settings are listed in the manual and the VFD will run on those settings out of the box. However, it will NOT be set up correctly for your motor until YOU change the releant settings.
Happy to help you get there, but you do need to read the manual, so we can communicate in the same terms. Once you get your head around what a VFD can and can't do, you'll be fine. What it certainly can't do is find out what motor you connected it to or read your mind about what you want it to do on your machine
(I have 8 VFDs running most of my machines - 4 of them are Huanyang 23Bs)

PS: tell me what equipment you are fitting it to and what the motor plate says - all of it - maybe a photo would be good. ALo, you didn;t mention if you are connecting the VFD to 3-phase or single phase power in your shed.

I'm still at a lost. This is my terminal board .. I will gladly give a reward to who ever can get me back into this drive. I think my only other option is to purchase another drive.

Hi again.
The photos of your manual and connectors solved the mystery for me: you have a GT series (vector controlled) inverter. All the responses you have had so far relate to the much more common SL or HY series inverters..... No wonder nothing made any sense to you.
Now, to get you going again, we need more info: please tell us EXACTLY what the model of your inverter is, e.g. GT-7R5G-4 or similar. See if you can also copy or photograph any labels on the inverter cas that show technical data.
That will tell us if you have a 3-phase inverter or single phase and the voltage it is expecting to be supplied with.

I managed to find an on-line manual for the GT series, but would like to know if it is the same manual you got with your inverter. Please compare it so we can refer to page numbers and headings when we correspond here. THe manual I found shows quite a different front of the inverter case compared to your first photo. That concerns me a bit....

Right now I'm reading about factory reset and will get back to you when I have an understanding.
I'm attaching the GT series manual that I found here. Please confirm that this is the same manual you have.

Yes that's the one. 7.5kw 220 single phase input with 380 3 phase output

OK, Still trying to find time to read the manual.
So far I can tell that you have accdentally set the VFD to be controlled by RS485 PLC network.... that you don't have I haven't found how to reset that yet....

Also, that manual is for entire range of GT series VFDs. I still need to know exactly which model number VFD you have.

There is no 220V 7.5kW model listed in the manual, and I don't believe there is a Huanyang inverter that puts out 380V with a 220V input!
If you look on page 3 of the manual, it says "Output Voltage Range: 0~rated input voltage" - that means the VFD controls the output voltage from zero to the INPUT voltage (whatever that is where you live), no higher. There have been several reports of dealers giving wrong information - probably based on translation errors rather than mischief.

So please let me know what motor you are connecting to it - best to photograph the motor label too! Then I can tell you if that VFD is even suitable for that motor.

Please answer some of the questions I've posed previously (3-phase in your house or single, model of the inverter, label details on side of inverter etc...)

I'm determined to help you, but I need better information from you to do so. This technology is not trivial and most electricians don't have a clue either. On top of that is the problem that a lot of misinformation is put on the internet and pretended to be fact.....

Hi creative,
I cannot find any way to rest the VFD in the manual, except by setting the parameter P0.17 to 1
To do that, I suspect you first need to clear all faults according to 5.2.2 on page 25:
"Fault reset
If fault occurs to the inverter it will inform the related fault information. User can use
STOP/RST {or according terminals determined by P5 Group} to reset the fault. After fault
reset the inverter is in stand-by state. If user does not reset the inverter when it is in fault
state the inverter will be in operation protection state and can not run"

Without further information and photos from you, I can't give you any better help.

By the way, have you asked your supplier for assistance? There might be a 'reset key combination' thats not in the manual...

I have already ran the motor with the vfd at another time. I was trying to set it up with my mach3 through a mach3 usb board... http://www.automationtechnologiesinc...breakout-board as per the drawing in the manual. And no luck as figured. I just purchased a rs485 to try to communicate with the drive and again no luck. not sure if its on my end or the settings in the drive but I can't communicate with it. There must be a way to bypass the external controls so it can be ran at the control itself. Here are the pic of the motor and the drive info. I can't imagine that after the settings are set for external that you cant get back in via the main control on the unit. I'm sure the Chinese have a way of doing it but I can't find the info anywhere. Good luck. I'm on the verge of having to order a new drive which is hard seeings there is nothing wrong with the one I have if I could only get back in.IMG_3277.jpgKIMG0174.jpg
