    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
    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?

    ATO Responded
    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:
    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?
    From: Robb | Date: 28/11/2021
    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.)
