Why would you want to do this and also why subject the VFD to all this extra stress? There is no benefit that I can see in doing this.
Just put in an extended ribbon cable for the controller and mount that somewhere handy.

It's a practical issue if anything, as you suggest, you still need a choke on the cable (stray RF) and is it reachable during operation, especially if you have to push the emerg stop.
If its going up and down, this would be difficult

The other issue may be harmonics induced by the cuts travelling into the electronics could pose longer term problems. You have to route power up to it too.
I would suggest mounting it closer to the front where you can reach it or use M3/M5 commands via a relay to start and stop, with speed control via a PWM-DC output unit like Peter Hommand DG-03 or 05. I did this and the unit is now tucked away towards the rear out of harms way and stray swarf/dust

Thank you for the reply Mike. I am going to run the cable so that I can controll it with Mach3. I will look into this over the next week or so.

I have run a long ribbon cable as Bob suggested for the short term. Thanks Bob.

As pointed out, another issue would be dust etc. Best I leave it at the back in a protected area.

I appreciate the feed back. Thanks guys.

The compressor turned over, but it didn't get the necessary motor speed needed to charge the tank.

Are VFD's limited in their applications and do they not work well in replacing some 3 phase motor applications? Could the problem be in the type of motor it is trying to run. Star vs delta 3 phase?

What sort of compressor is it? screw?
With a compressor you would have to have a 240V delta motor(or a 415V VSD)
Also you may need to tweak a few settings so the motor has more torque starting up.
Was the tank empty when you tried this?

Dumb question I know but I'm having a proper senior moment and am unsure if I have actually changed the setting or not.

I can get to PDxxx but what do I press to see what it's setting is and after changing that setting, what do I press to keep that setting?

Also, can I get back to factory default before I start over? Don't want to fry anything because of a wrong setting.

All the spindle will be used for is a router table, no cnc, so I only need a basic setup.

Thanks

Hi John,
Once you get to PDxxx press "set". PDxxx will chnage to the set value of the parameter. Pressing "set" again enters that value(assuming you havent changed it) and takes you to PDxxx+1. You can just keep pressing "set"to take you all the way through the list.

You cant restore factory default to one parameter if thats what you are asking. PD013=1 restores all parameters to factory(be aware that factory default of the VSD and the manual can be different).

Hi all, I recently purchased the Huanyang HY01D523B along with a water cooled spindle. My issue is I am getting a error code DL. When I hit RUN the spindle starts for a split second then the drive faults out with DL. I am running Mach3 along with a Gecko g540 plus warp9 smoothstepper. What I have done to try to solve the problem is; I disconnected the control wires going to the gecko and using the drive manually. I have rewired the vfd to motor wire. As for motor wiring I have 3 16awg conductors in aluminum flex. I replaced that temporarily with 18-4 shielded cable thinking the flex was insufficient. I read a post where a person used pin 4 as an earth ground the the motor casing with a wire going back to the earth ground on the vfd. I tried that. Also read that a guy removed the spindle from the mount and it worked due to a grounding issue with his machine. Tried that also. I have tried everything that i have read on this forum and other forums. All the tests were done without it being connected to the gecko. It has been completely in a manual standalone state between the vfd and the spindle. If i remove the wire from the motor the drive starts and ramps up like it should but as soon as i connect it and restart it it faults out. Bad spindle? Is there a way to check for a bad spindle? Any help would be appreciated!

Hi mrstevens and welcome to the forum.

First off, I found it quite difficult to read and understand the problem due to the formatting of your letter. Would you mind breaking things up into smaller paragrahs please. I am getting old and my eyes aren't as good as they used to be.

OK, to the problem.

First off, I note that you are from Georgia. Huanyang HY01D523B is for a 220 volt 50 hz supply voltage. Are the voltages and Hz correct for your area?

If the vfd works without the spindle attached and you have set the VFD PDs as advised earlier in this thread so that the correct voltage and current are being output then the next thing to do is to measure the resistance between each connection on the spindle and also to earth. So, measure 1 - 2, 2 - 3, 3 - 1. Then 1 to earth, 2 to earth, 3 to earth.

Do this in the first instance via the plug attached to the wiring and then again with the top of the spindle removed and all wiring disconnected. From these measuremwent we should be able to tell if the spindle is faulty or not. At least, as far as the electrical side of it goes.

The dl code is for a short circuit somewhere on the ouput side

Hi all.

help identify faulty Huanyang HY01D523.
the converter is switched on the display with a frequency of once every two seconds a message appears "as in the picture." in the documentation not found.
I would appreciate a hint the search location.

Gday Folks,

After reading this whole thread I find myself at a complete loss. I have an old woodlathe that is being converted to variable speed using one of the HY VFD's and an old 3 phase motor. To cut a very long story short my friend has set things up so that the VFD will run from 10 hertz to 100 hertz. It will do this without the potentiometer connected but will only run to 70 hertz with it connected.

So if one of you may have an answer to the problem it would be greatly appreciated.

Ross.

It sounds like your potentiometer is not wired in correctly.

Thanks Bob, will have to have another look at that.

Did you see this and make certain that you are set up in this fashion for the speed control?

Hi all. Firstly thanks for the many informative posts on this thread.

I've written a standalone controller app for use with this VFD. It's based on the work of Scruffoid and his Spindle Talker 2 app which was invaluable in getting my own working. See below for screenshots. More details are available on https://github.com/GilchristT/SpindleTalker2/releases where you can download a copy of the program and/or the source code (Visual C#).

Unfortunately it's Windows only. You'll need to have the .NET 4.0 Framework or above installed.

This is a beta release and still needs some work. If anyone's interested in it, I'd love to hear any feedback. I'm posting slightly earlier than I would normally release code because I'm heading out to Australia for a month so it only seemed fitting to post here first

This looks brilliant! Very nice work! Thank you or sharing.

On a slightly other note after reading back in the thread for a bit:
"Wenzhou Fullwill Electric Co., Ltd." is the manufacturing company of the Huan Yang VFD (www.fullwill.com.cn).
I contacted them a few weeks ago to see what would happen if I tried to dal with them directly. They would actually be quite happy to sell to people like us directly, but freight from China is just too expensive for single orders (about US$100 - slightly less with a bit of pushing and shoving). That just doesn't compete with the freight deal mass importers get via Hong Kong. Sadly.
The other thing I learnt is that this is a State owned or controlled power electronics company. As a result, the State owns the IP for any developments. So when the CEO of another State controlled company is well-connected in the party, they can get that design and make exactly the same goods - even under the same name! Herein lies the problem for us.... Chinese business and manufacturing culture is communist and very difficult for us to come to terms with. These practises ALWAYS include opportunism which we would just call 'cheating'. E.g. the second manufacturer might find IGBTs or other components with 10% lower specifications work just as well at a small saving per unit. These 'new and improved' specifications are reported back to the State IP holder. The next manufacturer down the line does exactly the same - until the number of failed devices outweigh the profits. Since this is communism, it might take a long time before anyone in charge notices.... Then sometimes the chief purchasing officer just 'disappears' and the new one is warned to stick to the approved specs. That's just how it is. This is how the USSR operated too. Different cultures, different practices.
Taiwan does not have the same culture and neither does Korea and certainly not Japan.
So we never know if we are comparing Chinese apples with Chinese apples - and we don't like it.....


PS: translations of operating and other manuals are all done by the State run 'Central Translation Association'.The manufacturers have no influence on that and it is 'bad form' to check up on their work and hazardous to the company to question or criticize.... I offered to help for the HY manual and was informed in not uncertain terms to 'cease and desist' further correspondence on the subject. I guess their e-mail correspondence is checked.... When I negotiated a price and delivery of a couple of I-Gaging scales a few of months back, I received an e-mail from the Chinese State export facilitating office to see if they had arrived and if I was happy with the transaction and the goods. We really have no idea how valuable our freedom and privacy is, do we?
