Tips: Variable frequency drive harmonic wave problems and solutions
The devices that have switch effect in VFD main circuit will produce harmonics wave in the process of on-off circuit. The lower harmonics usually have large effect on the motor load, causing the torque ripple. And the higher harmonics increase the leakage current of the VFD output cable, causing low output. Harmonic wave interference can also lead to misoperation of the relay protection device, so that the electrical instrument measurement is not accurate, or even cannot work properly.
The treatment of harmonic wave problems is to cut off the interference route transmission and suppress high harmonic wave of interference source.
The methods of cutting off the interference route transmission:

Cut off the approach of common ground wire propagation interference. The ground connection of the power line and the ground connection of the control line should be separated, that is connecting the grounding terminal of the drive device to the earth wire, and the grounding terminal of the control device to its metal shell.
Set the signal line away from the interference source power wire. Wiring separation is effective in eliminating this interference, that is, to separate the high-voltage cables, power cables, control cables, instrument cables and computer cables wiring.

The methods to suppress higher harmonic wave on the interference source:

Increase the internal impedance of the VFD power supply. Usually the internal impedance of the power supply device has the function of buffering the reactive power of the DC filter capacitor. The larger the internal impedance, the fewer the harmonic wave content. The internal impedance is the short circuit impedance of the transformer. Therefore, when choosing variable frequency drive power supply, the best choice is large short circuit impedance ones.
Install the filter. In the front of VFD, install the LC-type passive filter can filter out 5 and 7 times of high harmonic wave.
Install the reactor. Install the line reactor in the front of VFD to suppress the overvoltage on the power supply.
Set the active filter. Active filtering can automatically generate a current that has the same amplitude and the opposite phase of the harmonic current, so that can effectively absorb the harmonic wave current.

Questions about 2hp VFD

I have one more question, actually. Does this 1ph To 3ph, 2hp VFD require a line neutral ground connection? The only outlets I have available are either 120V line-neutral-ground or 240V split-phase hot-hot-ground connection?

ATO Responded

The dive input can be 240V split phase hot-hot-ground connection. Just connect the 2 hot lines to VFD L,N input terminals, it works with no problem.

Our confusion about VFD settings

We are setting up the VDF, but are a lot confused.
We need it to start at 5Hz. It should be P020, but when we set that to 5, the VFD starts at 0 and runs to 5Hz?
We set it to 60 and it starts from 0 and accelerates till 60.

Please set P2.01=5, and test again.

My doubts about VFD installation

Can I just install your 7 inch HMI to your GK3000 variable frequency drive without a plc? And everything works ok?

From: Bletscher | Date: 18/11/2021

Was this review helpful? Yes No (0/0)

ATO Responded

If there is no PLC, you can install HMI to vfd, but you need to program the configuration parameters yourself. So it is easier / better to use PLC.

Can a VFD be programmed?

Can this VFD be programmed to reverse for a few seconds and then return to forward automatically?

From: phandler | Date: 12/12/2022

Was this review helpful? Yes No (0/0)

ATO Responded

Yes, it can be, but your motor must be a three-phase motor, and the speed of reverse rotation and the speed of forward rotation (frequency) must be the same.
That is to say, the three-phase motor and VFD can be programmed to reverse for three seconds each time they are started, and then run forward, but the reverse frequency is the same as the forward frequency.
