It came with a manual, about 32 pages in English but the English is 
obviously very fuzzy. Much meaning is lost in the translation. One 
fellow on youtube says he ordered a Haun Yang and got the YL620-A which 
is the same thing, but they aren't by a heck of a long row of apple 
trees.

But I didn't specifically order a Haun Yang. I did have one ordered thru 
Amazon, but amazon got me PO'd because although I had registered a new 
card number, there was not a way to disable the old one on that page, so 
they declined the prime payment because they tried to use the old, 
stopped card number, but it took them 4 days to tell me. By then since 
it hadn't arrived, I'd went looking on fleabay and found this poor clone 
for 5 bucks less with shipping, so I canceled the amazon order since 
this clone got here a week faster than amazon would have w/o the prime.

You all know me well enough by now that amazon got a call from a rather 
PO'd customer over that. Amazon has left a bad taste in my mouth 
everytime I've tried to deal with them, and my history dates back 5+ 
years.  They write checks with their advertising their ass can't cover 
and I've been sick of their take it or leave it attitude for years. I've 
paid for prime, which is an annual fee I guess, 2 or 3 times, and have 
actually made it work once.  That dual mister kit? Didn't qualify, took 
8 weeks to get here. And IMNSHO they are junk. Far more air leaks out of 
the joints than makes it out the nozzles.

This fellow has I presume given up as he's not made a new video 
describing his success, so I expect he's muddling along like I am.

Preamble, I haven't read this thread in it's entirety, but, have you
searched long and hard for a manual?
I think your time would be better spent searching for deciphering already
done by others, since there must thousands of these devices running

Somebody might want to write this down FFR re the YL620-A vfd's, I've 
found the means to make LCNC's s command set the speed, see page 20, 
P07.08 thru P07.15.  I set all of those 8 registers up from 2 to 3.  
Probably only one is needed, but I played CMA and set them all to 3, and 
the front panel knob is dead but s12000m3 fires it right up.  But it 
still has no low speed current boost, slowly coasting to a stop at 63 hz 
output. Its also quite unstable at speeds below about 6000 revs, 
obviously hunting badly.

P00.12 is zero, has a range to 4, and has a label "VF Curve Setting", I'd 
assume 0 is off. P00.00 is supposed to be mains frequency, defaults to 
400 on error, and is an error if set below 150. Ack the booklet, factory 
is 50.00 but a full reset puts it back to 400. ???

Anyway, some progress!  Yay!

Turns out the left digit was showing a F and a number that would be the 
frequency IF it was running, which at powerup, it wasn't.

This XGRB is i believe a typu, I have found it called XGND other places 
in the booklet.

[... separete grounds for analog and digutal]

I have done that now. Using 2 cables, but have yet to slip some heat 
shrink over the drain wires used for the analog GND, and the digital 
switches FWD, REV version of XGND. 

I scrounged thru the pile of scraps behind the chop saw and came up with 
some 3/4" ply to  make a mount so its screwed down now.

This "thing" probable has 200 registers that report data, but are skipped 
in the booklets lists.  That alone is making the extra serial output on 
the 7i76 more appetizing, so what do I add to the hm2_pci loadrt line to 
make that port visible to the halmeter or dmesg?

Thanks everybody.

Yes, I found a poor pix of it in the booklet, titled "Digital Operator".

I hooked it up like I had the other, but when powered up it displays a 4 
digit error code. Rapidly blinking. But the only error code table in the 
back of the booklet only shows 2 digit errors with the left digit=0.

Unlike the OEM controller, the ground end of the external pot goes to a 
terminal named GND. But the FWD/REV buttons have a different, isolated 
XGRB. And because I don't trust the drain wires to be isolated from each 
other, I looks like I'll have to run a separate cable just to assure the 
grounds stay isolated. Sucks, such is not noted in the text, anyplace. 
Gr.

Or see if I've got 4 feet of cable with enough wires,  Need at least 6.  
But its turned wet. I've fed us lunch, might take a nap. My back is 
yelling.  Don't get old guy's, its not worth the aches & pains.

Whose brilliant idea was it to wire these things up thru ports in the 
bottom anyway?  Dumb, and dumber. Ought to have been power and output in 
the left side, control in the right.  Then you could just park it on a 
shelf.

If this is automatically translated from Chinese then you have to realize
that the Chinese
don't like to invent new words and in technical writing re-purpose existing
words.
The prime example is using "pressure" to means "volts".  This is a natural
result of
using characters, you can't "invent" new characters you must repurpose
existing ones.

A Chinese engineer would not even notice this as so many words and
characters
have meaning based on context or tone.  But the Google translator can not
understand context.  It is based on statistics

I assume that config changes are retained over a powerdown as having to
refresh its settings at every power-up is a complete non-starter to me.

Yes, the micro has a flash ROM to store the configs settings.

[Emc-users] nother probably silly Q

[Gene Heskett]

Greetings all;

This vfd somehow has the ability to save and restore its configuration 
data but the wording is quite ambiguous as to where its stored. 
Internally or externally in the controlling host pc. It uses the 
phrase "digital operator" which could translate to its own front panel.

Since I'm using a 5i25 driving a 7i76D, I fail to visualize a host com 
method that doesn't use the RS485/modbus port. Which I don't think I am 
going to try and use.

Is there some other way this might be possible? Or should I just ignore 
this chapter?

I'm concerned because poking the wrong sequence of front panel buttons 
could put it in the recall mode and any bad but stored random data could 
screw the moose.

I assume that config changes are retained over a powerdown as having to 
refresh its settings at every power-up is a complete non-starter to me.

Has anyone else any experience to share with this YL620 family of 
inverters covering the 1.5kw to 3kw range of applications at a source 
voltage range of 110 and 220 volts?.

Thanks all.

Cheers, Gene Heskett
