    Tips: Variable frequency drive heating problem treatments
    The variable frequency drive will generate heat in operation due to internal loss, which the main circuit generates 98% and the control circuit 2%. In summer, the hot weather will raise the temperature of VFD to about 80~90℃. Because of VFD is an electronic device with electron device and electrolytic capacitor. The high temperature can cause components failure, LCD screen no display, and also cause VFD protection action. Therefore, must dissipate heat for VFD in order to extend the life of VFD.
    General VFD operating ambient temperature is -10℃~+50℃. In order to ensure reliable operation of the VFD and extend the service life, VFD must perform heat dissipation. In winter, the built-in fan is able to drive the internal heat away. In summer, the temperature can reach 40℃, the built-in fan can only raise the indoor and VFD cabinet temperature. At this time the best way is to use the windows, or drill some φ500mm holes on the wall of the power distribution room near VFD, while ensuring in the cabinet around VFD there is some space, keeping natural ventilation. If this is still not enough, use built-in fan, or install exhaust fan and air flue around the holes to force out the heat. Moreover, the air conditioner can be the final solution for forced cooling.

    Perfect Shopping
    I received this 3 Phase variable frequency drive 3 days before. In these days, it works exactly beyond my expectation. This unit can run my 3 phase 60Hz grinder without any problem. I am satisfied with the service of this shop. Five stars given to this reliable 3 Phase VFD.

    About the setting of VFD
    How do I wire your variable frequency drive "GK3000" to restart automatically after power loss without using controls?

    You can do that, just set the VFD parameter P5.07=1, and test.
    VFD parameter setting
    Is there a setting to allow vfd to start at no less than 20hz every morning automatically, then produce as long as it can maintain freq. >20hz. Then shut off while awaiting more powerful sun condition without E.LU alarm that requires manual reset.
    If the freq>20hz operational control is unachievable, any automatic start and stop without alarm requiring human reset interaction would be acceptable.

    1. Automatic start and stop setting, Set the VFD Parameters as follows:
    P01.14=20(lower limit frequency)
    P09.14=1(lower than the lower limit frequency to stop VFD)
    2. When the VFD is faulted, automatically reset the fault EoL1, you can set the VFD Parameters as follows:
    P05.03=0 (define DI4 terminal without function)
    P05.02=9 (define DI3 terminal as RESET)
    P06.02=2, (define relay output terminal TA1, TC1 as fault output)
    P06.18=10.0 (output delay time)
    Also, you need to use the cable to connect these terminals TA1 to DI3 and TC1 to COM, see attached wiring diagram for your reference.
    will buy it again when I need it
    I JUST WANT TO SAY THAT OUT OF ALL VFDS I HAVE PURCHASED THIS ONE HAS WORKED SUPPER . No issues . I should have not listened to others and should have bought it . I would have saved 1000s. BELIEVE ME !!! THE USER MANUAL STATES HOW TO WIRE A SINGLE PHASE MOTOR EVEN WITH THE CAPPACITORS . I have used it with no issues and even showed to my friends who cannot believe the price and its functions . I will upload a video soon .
