Huanyang VFD Macro/ Plugin

[Tyknok]

I got the third adapter today, and have tried it with Spindle Talker, tried flipping the polarity....guess what, dosent work.

How about a picture of your VFD wiring?
And are you sure all of the VFD parameters are correct?

Yes, and also is your com port setup correctly? You are aware you can't have UCCNC started with the HY12 plugin enabled and trying Spindle Talker at same time or vice versa?

Please don't get insulted that there might be obvious answers to my questions but without asking leaves me guessing.

The fact that you tried to connect to VFD with 2 different computers using 3 different RS485 adapters and 2 different programs leads me to think your problem is with VFD wiring, parameters or a problem with VFD. My suggestion before purchasing third adapter was linking 2 comps to confirm if serial port is actually sending data, this would of pointed to where your problem is. I did a google search and there's a lot of info/youtube videos how to easily accomplish this test.

I will gladly take a picture from my wireing, but after I have given up on the RS485 I only have the 220v and the spindle cable connected.

At the moment my parameters is set to work with the RS485 adapter. If I change parameter 001 and 002 from 2 to 0 my spindle rund Perfect.

So, Yes, I would say the parameters is set correct.

Yes, I have never done that.

I could never get insulted on aomeone trying to help me ??

I must sek out this info then, I did a simple link last Night, coulden't make it work.

The VFD wireing for the RS485 is Two wires connected to RS+ and RS- correct? I did this, and have triblechecked that there actually is a working connection.

I'm not just trying to be a pain, I have tried a lot on my own before asking you guys for help.

What about PD163, PD164, PD165?

Did you have RS+ going to the A terminal, and RS- to the B?

PD163 = 1
PD164 = 1
PD165 = 3

Tried both polarity options.

Hi Dan

I have now done the serial communications port test as described on THIS page.
All adapters is working just fine, I can send and receive data from one PC to another.

I have tried different port settings and baud rates, on the VFD, no luck.

My conclusion is that the VFD is defect on the RS ports.

Sorry to read that Jan and thanks for the update.

Couple of years back I read a lot of the Huanyang VFD's were missing the U4 com chip from board, I wonder if this is your problem. Below is a pic with it missing and the red markings show where it should be.

The chip is there, and I have verified that there is a connection from the RS ports to the chip. I do not have the skills to look further into the Electronics, but I do have freinds on a Danish CNC Facebook site, that might would give it a try. For now, I'm trying to figure out how to Connect my UB1 to the analog control connections.

Once again Thanks for trying to help me.

OK, I finally got the spindle rotating, it´s controlled via 0-10V, I have adjustet the voltage to exactly 10V measured over DCM and VI, when running 24000 rpm. But, when adjusting the rpm to eg 12000 the rpm is not stable at all, it differs as much as 1000 rpm, up and down, but the voltage is stable at 5v. Is this somthing I have to live with, or can I fix it...and if, how?

If the voltage is stable on the analog input of the VFD and the motor RPM is fluctating then the problem is with the VFD, but there is one question that the voltage is really stable?
How did you measure it? With a multi meter or with an oscilloscope?

[ger21]

My Huanyang does the exact same thing when using 0-10V. I added some capacitors, and it got better, but still varied by about ±500rpm.
I found reports of others having the same issue, but was not able to solve it, so I switched to Dan's plugin.

but there is one question that the voltage is really stable?
How did you measure it? With a multi meter or with an oscilloscope?

I measured my voltage with a multimeter. The voltage never changed at all on the meter, while the RPM gradually went up and down over a 2000 RPM range. It took at least 30-40 seconds to cover that 2000 RPM range. If it was a voltage issue, the meter would have shown some change in voltage, but it was very stable.

[OlfCNC]

I think that if the multimeter will show the voltage fluctation depends on the time period of the fluctation.
If it fluctates fast then the multimeter will likely to show the avarage voltage instead of the numbers moving up and down.
The 0-24000 RPM if that is the RPM range for the 0-10V input voltage then 1Volt is 2400 RPM and 1000 RPM fluctation is about 0.41 Volts.
That should be seen on a multimeter if measured on the proper low voltage range and if the voltage is moving slowly enough.
But if the voltage is changing fast then the multimeter might not show it is why it is better to measure this with an oscilloscope that will show everything.

It can be that the voltage is really stable but the RPM is still fluctating but that definitely point out a fault of the VFD.

[ger21]

I have a video on Youtube that I did last year. The voltage reading on the meter does not change at all, and the RPM will constantly fluctuate, +1000, then -1000. As I said, it takes over 30 seconds for the 2000rpm change, and the voltage is steady the entire time.

[OlfCNC]

30 seconds is a long time. It is likely a VFD problem. But it is also possible that the carrier frequency of the PWM is close the same as the VFD sampling frequency and is a high frequency.
If the frequency is high the multimeter will not show the fluctation.
The VFD is measuring in periods and that always shift only a little bit on the PWM so the measured sum voltage and the RPM changes slowly as the measurement slowly walks through the PWM period.
Without measuring it with an oscilloscope this will remain only a theory though.
Another thing to try is to change the PWM frequency to see if it makes any difference but that will also likely to give results which could not lead to a final consequence.

I measured it with a voltmeter.

[ger21]

The breakout board converts the PWM to the 0-10V, so the VFD never sees the PWM signal?

Yes but how well does it convert the PWM?

[ger21]

If the multi meter says the voltage is stable, and never changes at all, doesn't that mean it's pretty good?
My voltage was always accurate to within .01 volts, at any rpm range, and was 100% stable. But the RPM was never stable.
