Late last fall I got one of the Huanynag "clones", haven't needed support, but the manual was pretty good, almost English, not the normal "Chinglish" with most stuff. I say "clone" because it isn't branded Huanyang.
.

I integrated one using the serial interface, supposedly it is Modbus but far from it, the manual does not even mention any of the codes, at least not the one I had.
I got the info I need from someone who had reverse-engineered it on the Mach forum.

I'm hoping somebody can pass a comment on how this would work with my motor.
He tells me it is reversible and the variable speed works fine and it will accept a stop start foot control with some extra external work.
.

Most VFD's have the same features, run from the front panel or set for external with potentiometer and P.B.'s/SW etc.
There is also an option for a series of pre-set speeds if needed, so they are fairly flexible to integrate.
The parameters are set from the front panel in order to set the motor characteristics etc. No. of poles etc, (4 in your case).

Thanks Max, I have taken a couple of extra pic's of inside the wire box.
I think somebody requested them previously.
So here they are for what ever it may do to confirm stuff.

 

The motor looks like it can easily be configured for 220 volt delta operation but to use it with the above VFD it needs to be left the way it is. (Star connected for 415 volts.) From what Max says about the manual that came with the one he had I would avoid it if your manual is that bad. If the manual has been sent to you in electronic format can you attach it to your next post. We should then be able to see if it gives enough information to configure it to do what you want.

OK Les, here is the info I was sent.

 

It looks like the manual you have is better than the one Max had.
The diagram of the connections to the forward and reverse micro switches and speed control potentiometer is on page 15.
The information for configuring it to use the micro switch inputs for forward and reverse is on page 37.
The information to configure it to use the speed setting potentiometer is on page 65.
I'm not sure if the forward and reverse inputs latch on and require a stop signal to stop or if the motor only runs while the input signal is present. (I think this is the way that you will want it to behave.) If these inputs latch then the Jog function may do what you want. The VFD I have
(A Teco) does not latch the forward and reverse inputs.

Thanks Les for taking some time to access this unit.
I am starting to feel like I am the right track now.
I am going to have a chat with a local electrician I know and just get his take on my project as he will probably be the first guy I call if things don't come together the way I was expecting in reality.

The ones I bought last fall came with a manual that was really better than my old Teco's. Easier for a layman(like me) to understand. It's pretty close to the one that fiftyv8 posted. It just doen't go into all of the detail about the different models that it serves.

 

That manual looks way better than the Huanyang version I got, for the different methods of control for the PLC input are shown on p90, 95, 96 .
Getting a little ahead, but there are also output in the PLC side for controlling different function at certain events in the VFD if needed.
Max.

 

Thanks Shortbus.
I found a local VFD unit, Chinese of course called www.chinafollin.com

They are offering me this ebay item.

The guy has also sent me a manual which does not mean a whole lot to a lay man like me.
I'm hoping somebody can pass a comment on how this would work with my motor.

Sorry for slow responses to posts, but the forum has dropped out a couple of times today.

I'm getting confused in this? I thought your mains was 220V, so why buy a 415V VFD? Usually the 220V are cheaper because they make more of them.

The ones I bought, got two, I paid $200 US. Delivered to the house. Don't know how that compares to $ in OZ though.

The OP says he has 3ph 415v which is much better than using single phase if possible.

OK, I thought his three phase was 220V, knew he had three phase.

 

Hopefully I am not confusing it with another post, I swore I read the OP had 415v 3ph??
@fiftyv8 please confirm.
Max.

 

Hi Max,
I too assumed he had a three phase supply and it was 415 volts (Phase to phase.)
Les.

 

Here in Oz we have 240V single phase and the 3 phase is 415V. At least that is the standard voltages.

That is what I figured, similar to UK.
Max.

 

Hey, I'm old what can I say? Been so many voltages thrown out there.

 

Yes 415 volts at 3 phase is what I have.
No problem with double checking we are not getting any younger these days...

 

Can anybody tell me with some degree of accuracy what the expected RPM would be for this electric motor of mine?

Thanks.

 

1385 at 50Hz I would not go higher than 100-120Hz with the VFD.
Result ~ 3000rpm.
Max.

 

From one of your photos it looks like it is 1365RPM
