YL620-A Variable frequency drive installation part 1

[@tukbuk2353]

The amplitude on the charts at the beginning of the video may be incorrect. I believe that 240V mains is 240V RMS (in the USA at least).

[@ImpracticalMachinist]

Yes that’s true, the charts are a simplification in that respect. While it might have been an interesting aside, the graphs are really just supposed to be an illustration of what is going on even if they’re not strictly accurate, it may have been confusing to say that the peak is 300-odd volts when we’re using 240v for programming the vfd.

[@dronesvisionsaeriennes]

Hello, nice video but on my side I am under FluidNc and despite the 10v/Gnd and Fwd/Rev connections I can't start/stop my spindle on my VDF YL620...I have P00.01=1 and P07.08=3...do you have any idea? Thanks..Philippe

[@StevePotter]

Looking forward to the next video with installation and testing. Thanks for the extra files!

[@ImpracticalMachinist]

Hopefully that'll be done soon. I was aiming for today but it's been quite a busy week.

[@levelone1234]

I am trying to hook this up to a commercial washing machine. It runs the machines, counts the quarters- but then resets and the machine doesn't start. Any help would be appreciated

[@ImpracticalMachinist]

That sounds like quite an interesting setup, how have you got it connected up?

[@oscar.f.]

Cómo reseteo eso?

[@ImpracticalMachinist]

To restore the factory settings go to P00.13 and select 10.

Hello Sir, What is the value for P00.00 (Mains frequency) for my Spindle 1.5 kw, 220 v, 8 A, 400 Hz water Cooled spindle. I have same YL620 -A- 1.5kw , 220 v Vfd I am having tough time in setting Vfd. Sir, can you share your Vfd setting. Thank you

[@ImpracticalMachinist]

P00.00 should be your mains input frequency. That will depend on where you are in the world, in the UK/Europe/Asia it would be 50hz. in the North/South America 60hz.

[@samtuladhar4009]

@@ImpracticalMachinist Thank you Sir

[@ScruffR70]

12:40 & 13:20 actually 10V - VI1 - GND are for the potentiometer (BTW it's an "i" for _input_ in VI1). A potentiometer would be connected across 10V - GND and the wiper pin would connect to VI1. However, I cannot find any useful documentation of the actual use of the AO (analog out - simulation output) nor of the electrical characteristics (i.e. max current) of the 13V pin. Also XVCC is somewhat obscure as it sources 15V but the docs call it "15V external input". The MO (triode output) is another obscure one I cannot find any useful documentation about.

[@ImpracticalMachinist]

Quite right about the pot terminals, frustratingly I didn’t notice the mistake while I was putting the video together. This arrangement seems fairly common among vfd’s with this sort of layout, it’s the same on my HY vfd. I’d be really interested to see what the AO actually does too.

[@jasonestes8954]

The manual says, "Please lower the carrier frequency when there is a longer distance between the inverter and the motor..." I see no settings to adjust the carrier frequency, but the specs do say it is adjustable between 1kHz and 15kHz. Is there a setting for Carrier Frequency?

[@ImpracticalMachinist]

It looks like the setting you want is P12.19 PWM frequency, by default it should be set to 8khz

[@jasonestes8954]

I see it now, thanks! I was searching for Carrier and could not find anything in the electronic version of the doc.

[@manyhatershere1721]

need to increase the volume... can't hear anything.

[@ScruffR70]

16:55 AFAICT these DIP switches are there to set the analog control voltage. 1100 would set it to 0-10V control while 0000 will set it to 0-5V control.

[@ImpracticalMachinist]

That’s quite useful to know, the problem is that with the corrections and input you and others have made I’ll have to go and make a new video.

[@arsyadtech]

Good job, like my vfd yl620a. Thanks for sharing

[@musicstore1897]

Hello, thanx for the video. Do you know how to restart this vfd to factory reset?

[@johannescordier7923]

Hey nice vid , is it just me or is the volume a tad low ?

[@tomrspears]

I have the same one and can't get it to go above 50 hz. I need 60hz. Any idea on which settings I need to change to get it to go to 60

[@Xenomorphin1]

Having issues with one of these - seems like my neutral is directly connected to my ground, which trips breakers. Do I have a lemon, or is this how it's supposed to be? Losing my mind looking all over the internet for anything of help. Even the seller doesn't know whether it's a fault or on purpose.

[@ImpracticalMachinist]

Obviously that’s not supposed to happen, have you checked the continuity between the earth and neutral with a multimeter? It definitely sound like a short somewhere. Is this the case with nothing else wired? No motor, no switches, just the power feed to the unit.

[@Xenomorphin1]

@@ImpracticalMachinist there is a direct short between ground and neutral. Like on the screw terminal of the vfd itself. Yeah, I have set the multimeter to ohms and I'm getting 0.5 ohm on it.

[@Xenomorphin1]

@@ImpracticalMachinist i have a switch on the way, but it wasn't the problem - I have removed the vfd power cable and then the entire enclosure, with 2 power supplies and 4 nema23 steppers and drivers was working wonderfully. Tommorow I'll be testing on just straight plug to the socket, dont have a cable handy so I have to borrow one from the neighbors.

[@ImpracticalMachinist]

@@Xenomorphin1 I'm having trouble visualising the setup. Are you saying that the VFD isn't wired straight through to a plug? If it's working outside the enclosure then there would seem to be the answer, you mention that you've got psu's and drivers, are you splitting the incoming AC between them with terminal blocks inside the enclosure?

[@Xenomorphin1]

@@ImpracticalMachinist it won't be working outside of the enclosure either. I'll update you after I test it.

[@NatureAccents]

hello..can you update setting for 400hz?

[@ImpracticalMachinist]

I’m sorry, I’m not quite sure which setting you mean?

[@NatureAccents]

@@ImpracticalMachinist what I mean is the parameter setting for 400HZ 2.2KW 220V motor

[@ImpracticalMachinist]

That’ll be according to whatever the specs are for your spindle. The spreadsheet is really just to provide a better, clearer translation of some of the programmable functions.

[@NatureAccents]

@@ImpracticalMachinist how about 2nd video?

[@ImpracticalMachinist]

When I get a free couple of days, I’m looking forward to getting it filmed.

i confirm at 16:45 its the RS485 communication

[@shakilshaikh8047]

Hello, Great explanation, any chance to get modbus working for this VFD? thanks in advance.

[@ImpracticalMachinist]

Modbus isn't something that I've played with yet, I have looked into it briefly and I'd like to try it out but it'll have to wait until I've got hold of a spare vfd, which isnt likely to happen any time soon.

[@andersmeiniche2746]

Thoes 2 screws in the buten is not Earth.

[@JALLAZZA]

Hi There, will you please post the page you used for the settings? I have the same vfd but the documentation is terrible. Im really having a tough time with the settings. I figured out "P03.08 = min spindle frequency/Hz" & "P03.09 = max spindle frequency/Hz".

[@ImpracticalMachinist]

If you have a look at the description you'll find the manuals and setup sheet that I showed, and also the one that i created (the third link) which is clearer and has the settings that I used for my setup, along with some notes explaining what settings do. Let me know how you get on, and if you have any more questions.

[@JALLAZZA]

@@ImpracticalMachinist Thanks for the reply, I got her dialed in. 🤠

[@JALLAZZA]

We got the exact same model.

[@ImpracticalMachinist]

That’s great to hear!

@@ImpracticalMachinist If you want I can send you the entire list of settings that I have compiled. It should save you a ton of time. Im running the YL620-A with 220v 1.5kw watercooled motor. She runs very quiet and smooth too with these settings.

[@yettimusafri4410]

hi! thank you for the video it help so much! any I have a problem with the inverter I need your help. The spindle is suddenly stops running and the VFD shows Error 4. I already watch some tutorial and i set up again by doing factory reset. The error 4 disappeared but when i try to rotate the panel potentiometer the frequency shows 10Hz the spindle is not move, until i set 47 Hz the spindle is move. But the rotation is different, it is less noisy but i feel there is something wrong. Do you have any idea? thank you

[@ImpracticalMachinist]

I suspect this will be your minimum torque settings. You’ll want to have a look at settings P00.09 and P00.10, which are the minimum frequency and voltage respectively. Have a look at the spreadsheet for the default values, and let me know how it goes. This might also be a problem with your potentiometer setting, you’ll need to set the minimum and maximum settings for the potentiometer to match the minimum and maximum output frequency.

[@yettimusafri4410]

@@ImpracticalMachinist I have try to setting P00.09= 0.2 Hz and P00.10= 1% but it didn't work

Try setting p00.09 to 5 and p00.10 to 10.
