Have this same VFD. Great video, thank you. Trying to power a General 350 3 Phase table saw, but not having any luck getting power to the motor at all. Really don't want to have to throw in the towel here as the saw is mint.
I can think of a couple things that might keep it from sending power to the motor. Maybe one of these will help. First, and I'm sure you've done this, make sure the motor is wired fro 230v and not 460v and that the T1, T2 and T3 connections are right on the VFD. Second, double check the safety switch settings for pins x1, x2 and x3. Make sure none of those are configured as a stop or safety switch. Those will keep it from sending power to the motor. Third, double check the setting for vfd control. Make sure it's set to the panel and not to remote. If that happens, it will look at pins x4 and x5 for control and disregard the panel inputs. I'm sure there are other settings that could impact it, too. Mostly, check what the programmable pins are doing, check to make sure it has panel control (and not remote) and double check the motor configuration.
Thanks for making this awesome video! I was wondering what setting needs to be changed to use a different potentiometer. I got it hooked up but I can only control the speed from the vfd. Thank you!
Hello I install a small hydraulic elevator in my home with vfd but the motor not working is connected to U V W terminals i cheque on the motor and only 24 volts show is something wrong with ufd or need programming thanks
Sounds to me like it needs programming. The output voltage is frequency based so it may not read the voltage you expect. The voltage, hertz, number of poles and max RPM all need to bre programmed (at least on the one in the video) for it to work. Is yours a dual voltage motor?
definitely keeping this one in my watched history...NOW I don't feel as intimidated by the setup my 100 yr old lathe came with...14" swing Joseph Crawford machine shop lathe with a 5hp 3phase and an amazon VFD...looks very similar to yours...Now that I have a better understanding...without the technical mumbojargonjumbo...just the meat n taters...I'm going to poke buttons once I find a copy of the manual somewhere... the problem I have, is the speed dial doesn't work...nothing happens when I turn it...lathe powers up an moves though...I have forward and reverse...but no speed dial I wonder this though...theres a FWD / N / REV drum switch between the VFD and the motor...would that mess with the speed control?
@@RobertAdairWorkshop No, I don't know unfortunately. I'm not very savvy with electric stuff. I know enough to not burn the shop down or electrocute myself. I found a similar unit on amazon. But there's no schematic etc. Seeing as how it's inline between the VFD n the motor, I'm going to bypass it and see if that works to get the speed knob working. I found a manual for the VFD online, failing the bypass, I'll start poking buttons. thanks for the reply!
Hi. I have a VFD to run a 3 phase tyre machine. Is it possible to trigger the VFD on when I touch the machine pedal? As it is, the cooling fan comes on and off (even when not in the "run" mode) and I have to press run each time I want to use the machine and wait for it to ramp up to 50hz. Also, I expect the fan running so regularly will kill it prematurely. To stop the fan running when not in use I am powering down the VFD at the breaker. Which is a bother since the breaker supplies other power outlets in the workshop. Any help appreciated. New Zealand
Have you considered breaking the circuit between the VFD and tire machine motor instead? Leave the VFD powered on, use a contactor style switch to interrupt the three motor leads as they come out of the VFD. I'm not sure if this would cause a problem with startup current draw, though.
Thanks! This is timely. Are the parameter numbers similar for most of the Shenzhen VFDs? I bought an Automation Direct for my Wells-Index mill and the voluminous manual reads like it was written by an English teacher. About to buy another from them for the table power feed motor on the mill. I just bought a 3 horsepower 3 phase lathe that has an ENC VFD. I found a manual on their website but OMG, the translation is so bad that I'm not sure what they're describing as the parameter descriptions. The ENC is set up very nicely with a reverse switch, E-Stop and speed pot but at the first glitch it will be replaced with something that I KNOW has an intelligible manual.
I took a look at the two manuals and the P-codes are different between the two VFD's I have. The ranges are same, so the 000X codes are setup for the VFD on both machines but what the parameters configure is different. I'll take a look a the badly translated one and see if I can make heads-or-tails of it, if you'd like two brains on it.
I have the same VFD, it looks the same and the manual looks the same. I figured out the manual and got it working for my drill press. I've got two questions - 1. Do you have low torque/power at low RPM and how did you fix that? 2. The emergency stop switch on the wall - how did you wire and program it to work? I've not been able to get mine working.
Here's a video where I show more of the installation: ruclips.net/video/kd4fgYpNiSQ/видео.html I did not have problems with low speed torque but I'm using the step pulleys in conjunction with the VFD which lets me slow down the spindle while maintaining torque. I wonder if changing the VFD profile (percentages at RPM) would help? I was never able to get the safety stop switch to work. I had it wired I not pin X1 and COM and programmed correctly but it never worked. I tried several of the other programs on those pins to see if any other functions worked, but none did. I cam to the conclusion that the programmable pins don't work. I suspect there is a software issue where the pins aren't polled correctly. I ended up pulling the VFD off and swapping it for a different one, the AT1. I kept the VFD and will use it on my surface grinder which has it's own shutoff switches. So yeah, not great. Check out the video I linked above if you have time. At the end of it, I talk about the problems with the programmable pins.
@@RobertAdairWorkshop Thank you for responding! I do have exactly the same VFD you started with. I also have tried all the same things. Betting the only way to get a safety stop to work is use the full external control button setup. The manual has a lot of undocumented settings; you and I both wish we knew what they were for! If I can solve the problems I'll be sure to let you know!
Thank you so much for the video. After watching it, the printed manual makes a bit of sense. (I have the same VFD). I’ll probably have to watch this video a couple of times to be 100% clear. I am going to this VFD for my Delta Unisaw (table saw). It has a 3-phase motor and runs on 220 volts. (I have 220 Volt in my home garage/workshop that’s why I am using this VFD. I have two questions. 1- The table saw has its own magnetic on/off switch! Would it be ok to use this VFD, considering the magnetic switch? 2- It seems that you have hard-wired your mill directly to the VFD, but I have installed a 3-phase, 220-volt surfaced mounted plug, which I will use, like any other electrical machinery for my saw. The only difference is that the supplied power to this plug comes from the VFD. Do you think it is ok? Many thanks.
I don't think the magnetic switch would be a problem with the VFD provided it is used to power the VFD and sits on the line side. I don't think you'd have a problem using a machine plug between the VFD and the motor. It'd have to be for T1/T2/T3 and you wouldn't be able to power it without the VFD. Essentially, you'd have a movable machine but one that wouldn't function unless it were plugged back into the load side of the VFD. All should work, I think.
I have a ASY AT1 inverter and a single phase motor, and my grinder is already fabricated. Can I make these work together? I found instructions online but for this configuration it specifies “AT2”. I’m really confused at the moment 😂
You'll need a 3-phase motor for the AT1. It takes in single-phase power and spits out three-phase power. The AT2 looks like it does single-phase power in, single phase power out. It also notes its for 220/240V so your 1-phase motor needs to be made for 208/220/240V. As an aside, 3-phase 240v motors are considerably cheaper and more readily available than 120v single phase. You might be able to get a 3-phase motor cheaper than that AT2 VFD.
There's really only a couple of things you can look at. The Chinese manufacturers don't publish much in the way of specs. I've chosen them based on motor size. I usually go 3-times the motor size I'm using. So for a 1HP motor, I use the 3HP vfd. Some of the VFD's accept 120V single phase and some, 240v single phase. Keep that in mind. You'll want to choose one that aligns with your supply voltage. Most 3-phase motors are 240v or higher, though, so it'll likely be based on that. I've used two different models with good luck from both: The AT-series (AT1) and this YL600 series. You'll find many different "brand" names for these but they are typically all the same specs/manufactuers.
It’s connected to a pin on the vfd’s programmable io header and shorts that pin to ground. I had to configure the pin for that function using the P-codes.
Bought 3 yrs a ago. Immediately the manual was garbage, That parameter page is completely black ( redacted) Ran it as shipped, for nearly 3 yrs, no power, motor cogs at low rpm, limited speed control. But usable Watched this a few wks ago and now just flashing numbers beginning with P or randomly push buttons and F something flashing. @ 2:25 "Select program" @ 2:25 " in the US its 60hz" IDK press a random button?

Glad it helped
Thanks for taking the time to make this video. It's perfect.
Glad it was helpful!
I did all the changes and motor still runs rough with vibration , motor works fine on another VFD from different manufacturer
Thanks for posting Robert. Not many videos explaining these drives for uses other than CNC spindles. Happy milling!
