    3 hp Single Phase to Three Phase VFD Details

    Tips: Variable frequency drive overcurrent
    Overcurrent is the most frequent alarm phenomenon of VFD.

    A. Phenomenon

    1. When restarting, VFD trips once speed up. This is a very serious phenomenon of overcurrent. The main reasons are: Load short circuit, mechanical parts stuck, inverter module damaged, and smaller motor torque and so on.
    2. Tripping after power on. This phenomenon cannot be reset. The main reasons are: Module broken, bad driving circuit, and bad current detection circuit.
    3. The tripping is not happening when restart but when accelerating, the main reasons are: Acceleration time setting is too short, current upper limit setting is too small, and the torque compensation (V/F) setting is too high.

    B. Maintenance examples

    1. The VFD displays "OC" once starting.
      Open the cover and don't find any signs of burn out. Online measure IGBT finds no problems. In order to further determine the problem, disassemble the IGBT and measure the seven high-power transistors, the opening and closing are good. When measuring the upper half of the bridge drive circuit, find a circuit is obviously different with the other two. After careful inspection, find an optocoupler A3120 output pin and negative power supply short circuit. Replace it and test again, three circuits are the same. Finally install IGBT and everything running well.
    2. A 3 hp VFD displays "OC" and cannot be reset.
      First check the inverter module but don't find the problem. Second, check the drive circuit and find no abnormal phenomenon. It is estimated that the problem is not here, and may be in the part of over-current signal processing. Remove the circuit sensor and then power on showing everything is normal, so the sensor has been broken. After replaced with a new sensor, the on-load experiment shows everything normal.
    Existing reviews of 3 hp VFD, Single Phase to Three Phase VFD
    Works great, excellent vfd.
    I received my VFD in a few days and it took me a while to set up the power, but now it is up and running. This 3 hp VFD is better than described, I waited to review till I had it fully installed and cutting. Manual is very well written, and each word and diagram is important to study.

    Can I use your 3 hp Single Phase to Three Phase VFD for my saw
    Hi,
    my table saw has a 3 phase Baldor 3HP motor and I need a drive. Can I use your 2.2 kW variable frequency drive for it. 10A is good. The saw runs on one speed only will the VFD be a problem?

    If your motor is 3-phase, 220/230V, and your supply voltage is 1-phase, 220/230V, then recommended 5 hp (4 kW) 1 phase to 3 phase VFD. Buy it on: www.ato.com/5hp-vfd
    I have some doubts about 3hp VFD
    Does the 3 hp VFD, single phase to three phase VFD SKU: GK3000-2S0022 have the ability to put out 415V when connected to a single phase 240 volt connection? If so, what amperage input line do I need to connect to?

    Was this review helpful? Yes No (0/0)
    ATO Responded
    No, the GK3000-2S0022 VFD output is only 3-phase, 220/230V.
    And it can run motors with rated current up to 6-7A.
    Where is my 220V input supposed to connect?
    I want to hook up my new VFD. My manual shows 220V single phase input to be connected to terminals R, S, T. My VFD does not have those labels. my terminal block is labeled P , L, N, PB, E, U, V, W.  where is my 220V input supposed to connect?

    ATO Responded
    If the terminals of VFD you received marked P+, L, N, PB, E, U, V and W, then the 220V single-phase input should be connected to terminal L and N. (Some of VFD models show R, S, T terminals, and one of which is marked red and cannot be used without screw removal.)
    I put in the parameters you specified but still throws the error code E-09.
    I put in the parameters you specified but still throws the error code E-09. I took pictures of the nameplates as well as the wiring. On the VFD I landed temporary wires they are all black but I wire-nutted them in the proper places.

    1. First of all, the rated output current of the GK3000-2S0022G you bought is only 10A, and the current of your motor is 7.9A when the voltage is low. The rated current of the motor is very similar to the capacity of the VFD, which can easily lead to overload. So we suggest that you run the motor with no load when testing.
    2. The drawing you provided shows that there are contactors and other components on the motor, so we are not sure how your motor is wired. Please note that our VFD can directly drive the motor, and directly connect the motor cable to the VFD output terminals U, V, W without going through a contactor or other components. In order to confirm that your motor is wired correctly, please send us the wiring manual of the motor for further confirmation.
    I want to properly set it up
    I bought this VFD for a chain hoist. I entered all the correct motor parameters. But everytime I let it pick up to 60z and I hit my remote it immediately throws the E-09 code. Which according to the manual is an inverter overload condition. I want to properly set it up. Or if there is anything I missed.

    Please follow the attached quick setup document to check whether the VFD parameter settings are correct. Please set P0.09=10, P0.17=15, P0.18=15, P0.22=2 OR 3, And test again.
    If you still have problems, please send us the VFD & motor nameplate label, photos of the motor and VFD wiring, etc. for further confirmation.
    My confusion comes from the input wiring
    My confusion comes from the input wiring. In the manual the terminal diagram for the 220V 1-phase shows 7 terminals L1, L2, Blank, E, U, V,W
    I have wired the 3 phase motor to the E (ground), U (T1), V (T2), and W (T3). Unfortunately the unit's terminal is different than the manual.
    It has : 8 terminals - P , L, N, PB, E, U, V,W thus I am unsure as to how to wire the input 220V supply. I have a 2 wire plus a ground? I have wired the machine on / off switch to the fwd and com connections, as this was how my previous VFD was wired.  Is this correct?

    ATO Responded
    Regarding the wiring of the VFD, please connect the single-phase 220V voltage to the L and N terminals, and connect the ground wire to the terminal marked E. The on/off switch you used earlier needs to be connected to the control terminals of the VFD. You can refer to our demo video, please see on: https://www.youtube.com/watch?v=zxTVneMG5Jo&list=PLlo8RulDRnthBFbP4ydheukDSKw2hAfDn&index=27&t=61s
    Not sure if that is correct
    I set these settings on my VFD. The first one PP-01 I don't seem to have so I assumed it was a typo and set FP-01 to 1. After setting all I tested again and got Error-04. Re-checked and FP-01 reverted back to 0. Not sure if that is correct.

    If you set the parameters, please set again and got Error-04. Please re-set F3-01=1.0 F3-10=63 F3-12=40, and test again. Also, can you replace other motors for testing?
    I don't know how to do?
    I did test the hoist with no load but it doesn't work, I bought the VFD that you guys recommended to me. I just didn't know that it couldn't drive the hoist because of the contactors and components. I thought that as long as the hoist saw 240V 3 phase it would work.

    You can follow our suggestions below and try again.
    1. First, please make sure your hoist has a brake. If it has a brake, you need to trigger the brake signal and then release the brake before you can run the VFD, otherwise, the VFD will malfunction.
    2. As we mentioned below, our VFD is directly connected to the motor. The forward and reverse contactor your hoist was using before needs to be removed. But if you want to continue to use the previous forward and reverse contactor, using an external push button switch, you can change one control: Please use the contacts of the forward contactor to control the forward signal of the VFD - FWD-COM; use the contacts of the reverse contactor to control the reverse signal of the VFD - -REV-COM. Please refer to the demonstration video about the VFD forward and reverse control motor at: https://www.youtube.com/watch?v=nBUm4i9wnzY&list=PLlo8RulDRnthBFbP4ydheukDSKw2hAfDn&index=12
    How to program in this VFD?
    I will be going to a job site in the next couple of days in which I need to program approximately 20 of the GK3000 VFDs. The VFDs are connected to exhaust fans. The fans will run continuously at 25Hz and then we want them to ramp up to 60 Hz when we send a signal from our relay. We have a normally open dry contact.  When the relay closes we want the VFD to ramp up the fans to 60Hz. Can you send me step-by-step instructions on how to program this in the GK3000.  I have the manual, but I am not finding the instructions to be very clear (for me…I am not normally the one who programs VFDs so a lot of the information is new to me).

    If the VFD you purchased is not 120VAC input, you can refer to the following parameter settings:
    If you would like the VFD to run at 2 speeds, you only need to configure an external contact x1 to achieve it. The parameter settings are as follows:
    P0.01=2 (frequency comes from digital given)
    P0.02= 25HZ (0 segment speed, when X1 and COM are disconnected)
    P0.03=1 (terminal control mode)
    P4.00=1
    P3.26=60HZ (1 stage speed, when X1 and COM are closed)
