The operations of using VFD for single phase motor speed control are not complex. In this video, ATO will show you details about running a single phase motor on a VFD. It's important to note that there are two wiring methods for single phase motor connecting to ATO single phase VFD: wiring of removing motor capacitor & wiring of keeping motor capacitor. At first, you should choose the wiring method you needed, and then set basic parameters step by step.
1. When it is set to vector control, the P1 parameter group must be set, and it is not necessary to set it at other times.
2. Note: Before driving a single-phase motor, the input phase loss protection and output phase loss protection must be turned off (P9-12 & P9-13=0)
Now the VFD has been updated to the new GK3000-2S series: www.ato.com/single-phase-vfd
Will this work on a 1 1/2 hp ac motor on a belt grinder so I can slow it down?
Where is the auxiliary winding tip connected after the capacitors are removed?
Because when the motor is powered by load, it seems impossible to start without an auxiliary winding.
I keep hearing to use a 3 phase motor what is the difference?
I also can use this if I electify my backyard railway with 220V 50HZ third rail, for example, I hook up a throttle to the vfd if I can hook up it to a throttle, but then, I need to calibrate the vfd next to the throttle potentials, and then, I need to hook up the neutral to the wheels and the live to the contact shoe, then I need to electrify my railway next to 220V 50HZ coming from third rail
Most of our VFD have been upgraded (series KE becomes GK series). If the programming code is found to be inconsistent during video viewing, please find your satisfactory video in this VFD playlist，th-cam.com/play/PLlo8RulDRnthBFbP4ydheukDSKw2hAfDn.html&pbjreload=10

I want to Know about the AIWA Fully Automatic Washing Machine Inverter Operated.But want know it works on single Phase VFD Option is that to Operate on adujusting a RPM (Speed can Regulate).
This is a single phase feed to the drive but a 3 phase feed to a 3 phase motor. The title of the video gave the impression that the motor is single phase.
It is a single phase motor.
@@ATOcom But the motor has 3 wires, looks like a 3 phase motor to me? Or it was a 3 phase motor with a built in phase converter to run it on single phase anyway (what the 2 caps were for).
@@h82fail google it. A single phase induction motor has 2 windings, one of which has the capacitor.
is there one that ouputs 120v single phase?
Sorry, there is no 120V output.
You can configure any vfd to decrease voltage. If you need to use vfd to control not 3-x phase motor then you should use it in V/F mode. And in case, that stop in warning, you can turn off the control of symmetric (it may have other name in the config of your vfd).
bagaimana cara memprogram inverter micno KE300A input 3phase to 3 phase output..mohon solusinya..
Please please please reply (we are planing for a home project)
My requirements
Input 220 single phase AC
Output single phase and three phase AC (both needed )
Power upto 3 HP
With forward, reverse, and variable noob (min, max noob) away from vfd or control panel
1. 1-phase input & output link, www.ato.com/3hp-vfd-single-phase-input-output
2. Pay attention to the rated current,
3. This is a list of related operation videos, th-cam.com/video/L3Lagbg9NXs/w-d-xo.html
Is there any sound with this video?
Sir amar 3 phase 20 hp motor k.. Single phase kore chala tey parbo plz sir janaben
Hi, thanks for sharing. Can you recommend a VFD for a smaller 120v 1phase motor, like 1/-4 - 3/4 HP ? Thanks again, - take care
Thank you for your message. Currently we only have 220~240V VFD, so it cannot be used on 120V motors. Sorry.

Can you clearly explain how this single-phase-motor VFD drives the START Winding that gets disconected from capacitor (normaly capacitor provide SOME PHASE SHIFT but not the exact angle delay of a phase #2 or phase #3 delay over 360 degree sin-wave)?
The value of capacitor in uF determines the phase shift and max current allowed through the start winding.
Matching phase angle and max current must be non-trivial, right?
Thank you for replies to this topic.
...a bit complicated.........thank you for your concern.
good question, and how about reversing the motor?
I asked ATO this same question via email (how does the VFD drive the start winding) and got the same kind of non-answer response. I don't think they know.
presumably the single phase motor is designed properly, the VFD should be able to drive the motor properly. Firstly you need to select a VFD a bit larger than the motor as only two phases can be used, the master phase needs to have higher current to get the same power as a three phase case. Secondly the phase protection has to be disabled as only two phases are used. Thirdly the two windings in the single phase motor are not made equal so before using the VFD, you'd better to find out the phase difference shifted by the capacitor. For motors have the starting cap, do not worry about that as VFD starts from 0 Hz so starting is not an issue. In a ideal conversion, the auxiliary winding which has lower current but a phase advanced by the running capacitor should be in series with an inductor or capacitor to wind back some of the 120 degree supplied by the VFD so that the total degree shifted to be kept about the same as if made by the running capacitor from the single phase.
The advantage of using a VFD in such way is you can adjust the speed. It also has lower starting current and some of the features VFD control provides but ultimately, only a three phase motor can deliver the full potential of the VFD.
I hope this info helps.
The vfd varies the applied frequency, to the live conductors. It doesn't control either start or run winding individually?
The capacitor does aid with phase shift in power factor correction. In a motor the phase displacement that enables rotation, is done by physically displacing the start winding. Caps just there too add torque in a motor.
Connected like this the motor gets to @30hz and then seems to struggle? It will not accelerate past 30hz.
Can the VFD connected to a single phase motor perform the CW/CCW function by pushing a button in a connection having the capacitors removed,or needs wire swapping every time which is difficult?
It is not possible to switch CW/CCW in the form of a button, because this is determined by the construction of the single-phase motor. with or without removing the capacitor.
if 1/2 hp 1 phase motor, should we use 1/2 hp (0.4 kW) VFD, Single Phase Input & Output
?
Not only the power must be ≥0.4kW, but the rated current of the VFD must also be ≥the rated current of the motor.
Can we change direction of single phase motor with vfd
Not, if you want change direction, according to motor nameplate.
these speed reducer exists for single phase motor
Hi, is that ATO Have VFD for motor DC (Motor 25W DC) ?
We have BLDC motor controller, what is your DC motor type? we VFD not for DC motor.
we can't understand what you are doing with that meter.
The temperature of single phase motor is more than three phase. Have you ever tested more than one hour? I can not solve this
Is your VFD frequency lower than the rated frequency of the motor?
@@ATOcom
Yes
@@bscsolar The cooling fan of an ordinary motor is directly connected to the rotor of the motor. Therefore, if the cooling fan of the motor is not independent, the motor may cause serious heat generation due to insufficient heat dissipation.
Bonjour. Je viens de regarder votre vidéo c'est vraiment très intéressant. Je voudrais savoir sur quel site internet on peut l'acheter. Si vous avez un lien du site internet veuillez l'indiquer s'il vous plaît. Je veuillez m'excuser mais je ne parle pas anglais. Merci beaucoup.
Do you have a list of resellers?
can you please help me? I have an item like you, I have a problem with the menu display not displaying (P0) so I can't program like the one in your video
Did you buy the VFD from ato.com? If so, please contact our after-sales service email: sales@ato.com, and describe the order number and the problem.
Now the ATO VFD has been upgraded, the video link, th-cam.com/video/D8zavX-9vVw/w-d-xo.html
Can run parrarel multiple motor with just one VFD Inverter?
Yes, but the power rating of the VFD needs to be large enough.
@@ATOcom i see, thanks a lot sir 🙏🙏
can i use this method with a 3 phase motor 4hp and with a VFD with 3 kw ( single phase in 3 phase out) ? i,m stucked please . i appreciate any help
The video is for the use of ATO single-phase VFDs with single-phase motors. Different VFDs have different usage methods. I suggest that you refer to your VFD manual for operation.
or...... maybe you need this video, th-cam.com/video/s6tTQdAVliM/w-d-xo.html
what I do if my motor uses a centrifugal switch?
Don't worry, the centrifugal switch will automatically turn off when the motor reaches a certain speed.
@@ATOcom so i just connect the motor directly to the VFD and carry on right?
@@Lucas_sGarage yes
Phase to phase current ?
What is the cost and where it is available?

This vfd works on china single phase motor?
Yes. But it has been upgraded and compatibility has become better. www.ato.com/single-phase-vfd
th-cam.com/video/D8zavX-9vVw/w-d-xo.html
the initial load of a 1 phase motor is 750w 1hp , to start 2x the initial load is 1500w, do I have to buy VFD 1,5 watt / 2hp ?
Audio would be nice for better instruction. but nice video
What are you talking about? There was audio at 1:53!
Can i use the same vfd to ac 1.5 ton compressor unit
Please reply
@@achyuthrao9005 Our VFD has been upgraded to GK3000-2S series.
We need to know the detailed parameters of your compressor, you can contact us by email.www.ato.com/contactus
Do you have video use single phase incase no remove capacitor
Like this, th-cam.com/video/D8zavX-9vVw/w-d-xo.html
Ciao, per un motore 220v, 2cv,1,5kw, monofase, questo dispositivo và bene? Ti ringrazio
Dice ad inizio video che questo è un vfd per motori da 2hp (cv in italiano) 1.5kw monofase
if I am going to use this to a washing machine, should I remove the capacitor also?
Yes, you should remove the capacitor.
@@ATOcom this applies to both main motor and drain pump? Just leave the capacitor terminals hanging?
@@LeoPestanas Leave the capacitor terminals hanging is OK, and this applies to your main motor and drain pump.
Hope our video can help you. Moreover, ATO.com offers you different power VFD, see more info on www.ato.com/vfd.
I did something similar for a single phase washer mtr. The goal was to lower start torque and current spike hurting consumer-grade contactors... so I simply used a SOFT STARTER. (Run speed rpm unchanged)
@@glasser2819 my washer needs to gradually ramp upto 1000 rpm on the drying cycle so as not to cause the washer to react violently to the sudden burst of torque...would the vfd connected to the high speed winding(and capacitor disconnectd) achieve this..thanks
How much?

how to connect single phase submersible motor
You can run submarsible motor
Hi
It can not be done. Single-phase motors will never run smoothly through a Variable drive. I am able to prove my point. The motor will overheat within the 1st 40 seconds......!!!! Good luck watching this video. Load balance is a b.tch.
Can I used this VFD to control exhaust fan using pwm with arduino or microcontroller?
