    Tips: Variable frequency drive hardware replacement precautions

    1. Replace the IGBT. Measure whether the resistance value of each road is balanced.
    2. Replace the drive board. Need to carefully check whether the plug and socket number is consistent.
    3. Replace the main control board. After replacing the main control board, set the application parameters, motor parameters and protection parameters of VFD.
    4. Replace the PG card. Check whether the terminals are normal. If the motor has a vibration or cannot rotate after replacing the card, need to exchange the A and B phase.
    5. Replace the communication board. Simply check the DIP switch set by VFD hardware station number, and then check that the communication light is normal.
    6. The communication board of some VFD series is an independent CPU. After the replacement, need to upload configuration program.

    Existing reviews of 1/2 hp VFD, Single Phase to Three Phase VFD
    VFD recommendation
    I have a three-phase, 220-volt, 4-kilowatt table saw that needs to be powered by a 220-volt single-phase power supply. I want to be able to stop it relatively quickly, and may need an external resistor. I hope you can give me a recommendation on this.

    How quickly the motor stops depends on the size of the mechanical inertia. The larger the mechanical inertia, the larger the busbar, the larger the current, and the slower it stops. It is impossible to determine how large a resistor is needed. Our VFD manual defaults to a braking resistor power of 10% of the inverter power for reference.
    The factory reset parameter
    What is the factory reset parameter for the ATO GK3000?
    From: Danica | Date: 14/09/2024
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Restore factory settings: If your VFD nameplate has 9000, please set Pd.01=1. If the nameplate does not have 9000, please set parameter P3.01=10.
    We need help
    We installed a GK3000. It has not gone well. We need help. How do we increase output voltage? We need a minimum of 208V, we are only getting 195. There is 240 going in. Got it to the “fun” stage several times but no further. Output reads low. We would appreciate any assistance you can provide.

    If your VFD has the number 9000, then you need to set the parameter P8.02=220V.
    If your VFD does not have the number 9000, then you need to set the parameter P0.08=220V.
    In addition, the output frequency needs to reach the upper limit frequency (rated frequency) for the output voltage to reach 220V.
    Question about change the configuration
    How to change the configuration from 50 to 60 hz?
    From: Nichaolas | Date: 05/09/2023
    Was this review helpful? Yes No (0/0)
    ATO Responded
    If you want the frequency to reach 60HZ, you can set these parameters:
    P01.08=60
    P01.10=60,
    P01.12 = 60,
    P02.04 = 60
    and test again.
    How to solve this error?
    Whenever I connect to the pc I am getting this type output in my realterm software , I am unable to provide input to the VFD. It continuously shows these irregular values as soon as I connect to the PC. How to solve this error?

    First, the communication configuration P3.09=163 means that the VFD is configured as Modbus RTU protocol.  The data format is 1-8-1 format, no parity, and the baud rate is 9600. But we noticed that the baud rate of the software screenshot below is set to 115200.  The baud rate is obviously different, and there is a problem with the communication parameter setting.
    Please share VFD configuration and Installation guide
    Please share VFD configuration and Installation guide. We want sudden clockwise and anticlockwise movements.

    For VFD configuration and installation, please refer to the manual: https://www.ato.com/Content/doc/ato-gk3000-series-vfd-user-manual.pdf
    For sudden clockwise & anticlockwise movements, please refer to the three-wire control mode on page 115 of the manual.
    Looking at a vfd for 5 hp motor
    Will this work if i set the motor parameters as on the motor plate for 220v output? I assume that would be as followed: 220V.  60Hz  1.4 amps and 3450 rpm.  If this is correct and this will work please let me know.  Thanks.

    It is recommended to choose a 1hp VFD, so that the power is a little larger than the power of the motor to prevent overload. See on: https://www.ato.com/1hp-vfd
    Function of VFD
    Thank you for the instructions. After thinking about it more, what I am looking for is a'Pause for X seconds' button. So I have 1 switch and every time the switch gets pushed, the VFD stops the motor, for X seconds. After X seconds, the motor starts to spin again. Can we do this?

    Was this review helpful? Yes No (0/0)
    ATO Responded
    Unfortunately, our VFD does not have the function you mentioned below. If you want the VFD to pause, wait a few seconds before running automatically, you may need to add an external delay relay and PLC programming control to achieve this.
    Very good 1/2hp VFD
    I have a machine 240V/50Hz, can be run at 240v/60Hz. I know the difference in speed is about 20% that will heat up the coil and burn the insolation? What do you recommend?
    From: Anon | Date: 26/08/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    We can provide a 1-phase drive that can convert the frequency, but the VFD can be used for motor individually, not for your whole equipment/machine, with direct connection between VFD output terminals and motor input terminals, nothing in between. Also, the motor will be fully controlled (on/off/speed control) via VFD buttons only.
    Issues related to single-phase to three-phase VFD
    I was looking at one of your single phase input and output drive. I just want to make sure it has the proper listings for the united states. UL listited?
