You appear to know your stuff when it comes to VFD’s. I have a question for you. To run a drill press that has a three phase motor do I need both a transformer and a VFD? Or just the VFD??
just the vfd works fine. wire the motor in a delta configuration to make it run on 230 instead of 380 (or if its a us model 110 instead of 230) if you dont want to disturb radio amateurs and want to keep your household power grid clean add a mains filter before the vfd.
How well would this VFD work with a modified sine wave inverter? Would the sinewave output be clearer or would it actually end up damaging this VFD instead or will it just be the same modified sine wave?
it should work and the vfd outputs a spwm which can be filtered into a pure sine wave but it might shut down with an error as it detects invalid phase curents with no motor attached
@@gamerpaddy That is good to know! I might plan on using this to power a vintage industrial blower on my solar setup in the shed. Currently I am powering it via a modified sine wave UPS as an inverter and it by itself can't get the motor to full speed or consume as much watts as it would at full speed. However I do have a vintage automatic voltage stabilizer and oddly enough it actually purifies the modified sine wave to a more pure sine wave. Every motor I connect through it becomes way more silent and reaches full speed without a problem. It does cost around 75w however since that automatic voltage stabilizer uses a transformer of sorts to stabilize the voltage. As good as it is, there is a downside to it other than the 75w. It likes to output around 300v instead of 230v. This is fine for the motor however since it and the capacitor are both designed for 230v and 480v. I might just have to invest in a pure sine wave inverter but those are really expensive
Hi thanks for your video top class. However I have a question, I would like to use this VFD for my lathe, according to the manual my lathe uses a one phase motor (230V AC) and has a starting capacitor. The motor according to the manual is an 400W type. Would it be possible to use this type of VFD. I have seen some information where you hook up the Z wire from the motor to T or the W. But I'm not sure if that will work, last thing for me is ruin my lathe motor. Looking forward to your comment or answer. Yours, Frans.
Can you tell me what is the resistance of the resistor R4, or what colours it has? Its near those 3 blue ones. Mine got burned and i can't read its colors to identify. Thank you.
its inrush current limiter which also acts as a fuse. check the rest of the circuit before replacing it. i dont know what value it is. most likely between 0.47 and 1ohms. i dont have this unit anymore. check rectifier for short circuit, check igbt module and smps ic for short circuit
hallo und danke für das Video. Ich habe auch so einen FU hier und keine Ahnung von Konfiguration. Gibt es ein Handbuch in deutscher Sprache? Wenn nein, kannst Du evtl. helfen/ erklären wie man das Gerät kosfiguriert? Das wäre riesig nett, vielen Dank
Hi. Thanks for your video, very explanatory. I've bought similar, under 40€ unit from AE and while connecting all the cables I was watching your video. In about 7 min mark you mentioned that everybody connect their own filter before VFD unit. What did you mean by that? I was going to connect my VFD directly to outlet.
switching inductive loads fast like vfd's on motors cause a lot of interference on the mains. you might add a mains filter before the unit to not disturb other devices or cause radio frequency interference. its not needed to run but if theres some ham operator nearby you will hear him sweat a lot when your motor runs lol. good vfds have built in filtering, this one is basically compareable to a laptop powersupply at 1/10 the power.. on higher power applications like 3kW and above you might even need a reactor / filter between the motor and vfd to not damage the motor, inductive voltage spikes can chew trough the isolation and short out the motor over time.
that's normal. that's basically because the vfd is sending pulses to the motor to vary its speed. a lot of vfds will allow you to make the pulse frequency higher so that it's harder to hear, but that can cause radio interference and tear through the motor winding insulation prematurely if you're not careful. it's best to just get used to the noise. it's one of the trade-offs you have to deal with if you choose to take advantage of the energy savings and controlability that vfds provide.
@@gamerpaddy i am referring to output, input is standard in each country. Is there a setting to change the output? I am thinking of using it on a coffee grinder that spins at 1400rpm @50Hz or 1600rpm @60Hz, so 60Hz is an option i would like to explore.
yes, but you need to wire your motor to delta configuration then it should work. then it runs on 220v 3phase. 380v motors are usually on star configuartion for 380v.
I found the manual when I wanted to set RPM as default on the display. Wondering if you figured it out. Not too keen on messing with settings unless I can jump straight to what I'm trying to do. Any help would be greatly appreciated!
@@gamerpaddy But it has RPM readout (frequency multiplied by thirty) function in the K1 selection menu. I believe it is option four. It always displays frequency on startup.
Thank you a LOT! Couldn't find the english datasheet anywhere, don't know how you found it but thanks!! And the first mirror is not working, just infinite ads. Do you know the manufacturer name?
Dose it support modbus rtu ? Or just pure serial connection over rs485
hy i cane to conect 4-20 ma sensor on this vfd?
The power supply only power the pwm ic, mosfet driver and the fan.
My VFD keeps showing an error code (E-0.2), i've tried every v/f compesation possible but no luck,
What am i missing ??
bad motor probably hook a current clamp meter on one of the phases and check which one is bad set v/f curve to motor frequency

no single phase motors have 2 windings you need a 3phase motor

I tried to download the PDF but the links just wants to try and install rubbish onto my PC, no document??
Me too.
I think that despite the sellers claim a maximum frequency of 100Hz it doesn't go over 50.
100hz output not input you have to change settings to go higher. but 100hz is low, most vfd's go to 400 and better ones even 1000hz

have you try to use the chinese vfd to bldc motor 220v
Hi.
Hast du schon mal den FU an einem einfachen 1-Phasenmotor angeschlossen? Geht das denn?
Viele Grüße :-)
can it be used to power a 400w 380v 3phase motor from a 220v single phase normal house outlet ?
yes, but you need to wire your motor to delta configuration then it should work. then it runs on 220v 3phase. 380v motors are usually on star configuartion for 380v.
do you know how to change the carrier frequency?
cant on this one its very basic get a yaskawa, fuji or danfoss instead.
thank you, do you think this one would work? Allen Bradlley Powerflex 4m @@gamerpaddy
it has adjustable switching frequency up to 10khz so yea could work

you cant display rpm because it doesnt know how many poles your motor has use a external rpm meter
@@gamerpaddy But it has RPM readout (frequency multiplied by thirty) function in the K1 selection menu. I believe it is option four. It always displays frequency on startup.
how about option 3.0 manual only shows 1 as option, but there may be more i dont have this unit anymore.
@@gamerpaddy Okay thank you for looking! Take care paddy 🥃

no idea, they are sold under many names. if you see ads on such websites, use adblock (addon for your browser).
can use this VFD for a direct drive motor .38 HP 140 rpm 60 hz is this unit programmable thank you for the help.
