    Note: ATO VFD Cannot be used as a power source, it Can only be directly connected to an induction motor to control the motor speed.

    Tips: Variable frequency drive storage notifications
    If the VFD is not used for long periods of time, it may be damaged, which is caused by the environmental conditions that do not meet the storage conditions of the VFD. Therefore, the VFD should be placed in the packing case when stored, and note the following:

    1. It is the best to store in absence of sun, no dust and dry place.
    2. The ambient temperature is best in the range of -20~40℃.
    3. The relative humidity is best in the range of 20% to 90%, without condensation.
    4. Avoid long-term storage in corrosive gases and liquids environment.
    5. Long term storage (2-3 years) will lead to electrolytic capacitor degradation. Adding voltage can self-repair certain degree of deterioration. In long-term storage, it should be regularly (within 6 months) powered on for at least 5 hours, and the input voltage should be gradually raised to the rated value by voltage regulator. If the storage period is more than 10 years, the electrolytic capacitors rubber sealed will lose efficacy and must be replaced.

    How to Measure Circuits with a Digital Multimeter?

    This video will show you how to measure electrical circuit using a digital multimeter.

    VFD Two-Wire Control Wiring with Push Button for Forward Motor

    In this video we've guided you through how to do VFD control wiring with a self-lock push button switch to run the motor in forward direction. We've covered everything from wiring to programming and even a test run. So just watch it through and hope you'll find it informative and helpful.

    4-20mA speed Control on VFD

    4-20mA is as common in analog control systems as 0~10V, and ATO GK3000 series VFDs are also perfectly compatible.

    How to Control VFD with 0-10V (CI port)

    This is port CI usage method for 0~10V to control the frequency of ATO GK3000 upgrade version. It is suitable for 1-phase, 1-phase to 3-phase, and 3-phase VFD.

    VFD Analog Input 0-10V Frequency Control (VI Port)

    ATO GK3000 VFD uses external voltage analog to control the frequency so as to achieve the purpose of motor speed regulation.

    Control VFD with Potentiometer & Button (VI Port)

    ATO GK3000 vector VFD supports control of synchronous motors, and supports external potentiometer and button control.

    Forward and Reverse VFD Button Control

    This video is for ATO GK3000 upgrade version VFD 1-phase to 3-phase & 3-phase VFD (3-wire control/external terminal control mode).

    VFD heat generation
    What is the heat generation of this VFD?

    Sorry, we are unable to provide specific heat data for the VFD at this time.
    Motor shaft voltage
    In my option, it depends on the horsepower of the motor. The costs of motor under 60 hp doesn't not justify insulating either bearing. 75 hp (360 frames) to the end of t frames roughly 250 hp in a 4 pole, i would just insulating one bearing. Everything after t frames I would insulate both bearing if being used on a VFD. After 2000 hp I would insulate and add a shaft grounding ring for insurance. The level of protection must be weighted against how critical the motor is, and the costs of the protection versus the costs of replacement/time to reorder.

    If you need a motor rated at 3000rpm minimum and a torque of 30Nm, then the power of the motor must be at least 10kW, and the voltage needs to be 72V or 96V to meet your requirements.
    If you want newer motor power and 24V voltage, the motor also needs to be equipped with a planetary reducer.
