    Tips: Variable frequency drive control mode

    Vector control
    Vector control is to control the size and phase of the stator current of the motor through the vector coordinate circuit, so as to control the excitation current and torque current of the motor in the d, q, 0 coordinate axis system respectively, and then achieve the purpose of controlling the motor torque. By controlling the action sequence and time of each vector and the action time of the zero vector, various PWM waves can be formed to achieve various control purposes. At present, the vector control methods actually used in the VFD mainly include the vector control method based on slip frequency control and the vector control method without speed sensor.

    V/F control
    V/F control is in order to obtain the ideal torque-speed characteristic, based on the idea that while changing the power frequency for speed regulation, it is proposed to keep the magnetic flux of the motor constant. Basically, general-purpose VFD use this control method. The V/F control inverter is very simple, but this method cannot achieve higher control performance. Moreover, at low frequencies, torque compensation must be performed to change the low-frequency torque characteristics.

    This video is about how to use buttons to run single-phase VFD of three-phase motors.

    The video shows the parameter setting methods for the V/F control mode and vector control mode of single-phase to three-phase VFD.

    This video provides insights into the wiring process for converting single-phase to three-phase VFD, specifically from 220V to 380V.

    I need help
    The VFD GK 3000 is throwing code E-19 but the input power has been measured by my electrician as not dropping. Please help me.

    This E-19 should be input phase loss protection, please set PA.13=0 (turn off input phase loss protection), and test again.
    Do all VFDs retain their settings when power turned off?
    I do have one question: Do ATO all VFDs retain their settings when power turned off? Or must they be reprogrammed after the power is off?
    From: Hahn | Date: 10/08/2023

    All of our VFDs have the function of retaining data and do not need to be reprogrammed after power is off.
    Are programming instructions in the manual valid for this non-standard machine?
    Are programming instructions in the manual valid for this non-standard machine? This GK3000 model for me is that my 1-phase power source is 8kW @ 240VAC. Should I disregard the specification in the manual that the only main circuit terminal for incoming 1-phase power is specified as 0.4-2.2 kW?

    1. The quick setup manual is valid for this VFD, and all GK3000 series VFDs can be set in this way.
    2. The power supply needs to be more than 20% larger than the rated power of the VFD. The VFD you bought is rated at 30 hp (22 kW), so the power supply needs to be above 26.4kW, and your 8kW power supply is not enough.
    Why the breaker will trip when the unit starts running meaning?
    Do you have any idea why the breaker will trip when the unit starts running meaning? We connect the VFD unit runs fine, but when we connect motor runs for about a minute and the breaker will tip and of course, the unit will turn off.

    We noticed that the information you provided looks to be a refrigeration machine, not a motor.
    Please note: Our VFD can only be used to connect the motor alone, not as a power supply for other devices, otherwise the VFD will not work properly.
    Do I need to order additional power of VFD?
    We were not able to turn on the panel on the unit to have the motor run.
    I see on this video that you have additional power on the bottom.
    Do I need to order that too?
    I don't have the unit here with me. I will take a video tomorrow and send it to you.

    What appears in the demo video is just a control button switch box, not an additional power supply. We use an external push button switch to start/stop the VFD. You can also directly use the VFD's operation panel to control and start the VFD, with no problem.
    You can set P3.01=10 (restore VFD factory parameters), reset the basic parameters of VFD according to the parameter setting instructions in the attachment, and test again.
    Note: After entering the parameter P3.01, there are 2 digits showing 00, you need to press the shift key >> to move to the tens digit, and then modify the value, and then press the shift key >> to move to the single digit, and set P3. 1=10.
    If there is still a problem, please send us the picture of the VFD nameplate label and the start-up video for further confirmation. Thank you for your understanding.

    Having an issue when turning on VFD
    I bought this unit GK3000-CS0220G, but we are having an issue turning it on.
    Can you provide a video or some help to make this unit work?

    What problem you've met when using this unit GK3000-CS0220G? Please describe the questions in detail and we will fully support you. Please refer to our demo video, wiring correctly, run VFD with No load, and check if it can run normally at 50/60HZ, please see: https://www.youtube.com/watch?v=zxTVneMG5Jo&list=PLlo8RulDRnthBFbP4ydheukDSKw2hAfDn&index=27

    Am I missing something?
    I purchased the VFD and it runs smoothly in VF control mode. However, when I try to run it in Sensorless Vector mode it runs very ruff, rumbling, especially in mid-range, 25-30 Hz.
    I followed the PA settings for the motor, 2hp 3phase 230v and 5.9 amp motor rated 10:1 PWM. I ran the auto-tune and still get the rough rumble in mid range. Am I missing something?

    Unfortunately, your VFD does Not support Sensorless Vector mode, the set PA parameter group is invalid, and you can only use V/F control mode.
    Application of VFD
    My application is: A cnc lathe with 20 hp. 3 phase 50A requirements. Can we use variable frequency drive with 1-phase, 220V input to 3-phase output to run such application?
    From: Stephanie | Date: 17/08/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Yes, but please, note that the VFD can be used for motor individually not for your whole CNC equipment/machine service panel, 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.
