    Tips: 7 points about variable frequency drive application environment
    The variable frequency drive may not be normally operated in any cases, so the user is necessary to have more understanding about load, environmental requirements and the VFD itself. There are seven points should be pay attention to:

    1. Because the motor temperature will be high under long-term and low-speed operation, the fan cooling capacity will also reduce, so it must use high reduction ratio VFD or 6 grade motor to let the motor running in higher frequency.
    2. The variable frequency drive installation site must require the standard environment, or it will easily cause failure or shorten the service life. The distance between VFD and driving motor should not be more than 50 meters, for longer distances need to reduce the carrier frequency or increase output reactor option to function properly.
    3. Type of load and VFD selection: Different load of motor has different requirements of VFD.
    4. Fan and pump is the most common load: They have the simplest requirements of the variable frequency drive, as long as the variable frequency drive capacity is equal to the motor capacity (air compressor, deep water pump, sediment pump, and fast changing music fountain need higher capacity).
    5. Crane load: This type of load is characterized by a great impact on the starting, so it requires a margin of the VFD. At the same time, there will be energy feedback when putting down the weight, so it requires brake unit or share bus.
    6. Uneven load: Some load maybe sometimes light and sometimes heavy, this time should be in accordance with the heavy load situation to select the variable frequency drive capacity, such as rolling machinery, crushing machinery, mixer, etc.
    7. High inertia load: Such as centrifuges, punching presses, cement rotary kiln, these kinds of load have high inertia with large oscillation when starting, and the motor may have deceleration energy recovery. So we should use higher capacity VFD to speed up the starting to avoid oscillation. And we can use the brake unit to eliminate the feedback power.

    Running a single phase motor with VFD

    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.

    Use of 1/2 hp VFD
    Could your 1/2 hp VFDs be supplied in explosion proof panels for offshore working conditions?
    From: Mary | Date: 06/05/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    No, we engaged in VFDs only, don't provide panels. But you can use simple local enclosure/panel if needed.
    Power of one phase variable frequency drive
    Do we have to derate the one phase variable frequency drive?
    From: Bdeko | Date: 13/05/2021

    See its specs/price, and you can order online by credit card on: https://www.ato.com/2hp-vfd-single-phase-input-output.
    I am interested in your VFD
    Hello, I am interested in more information about the GK3300 series of VFD drives, non-enclosed. Could you provide a manual for this series? I found a manual for the GK3000 series and imagine many things are similar. However, the main thing I wonder is how they are set up since it looks like there is no control readout, buttons or other manual inputs. Is this done with a configuration software maybe? Please let me know what info you can provide regarding this series.

    If you purchase the frequency converter non-enclosed, it will be equipped with a keyboard to realize input and display the reading function.
    Installation of a 1-phase drive
    What is the advantage of removing motor capacitors when installing your 1-phase drive?
    From: Kurt | Date: 07/02/2022
    Was this review helpful? Yes No (0/0)
    ATO Responded
    It is okay to remove the capcitors or not, the drive will work effectively. Just removing the capacitor may provide a little bit stability.
    Can the output of this SKU: GK3000-1S0004 VFD also do single phase 120V?
    Can the output of this SKU: GK3000-1S0004 VFD also do single phase 120V? I have single phase 120V input and need single phase 120V output.
