Existing reviews of 15 hp VFD, 1-Phase 220V to 3-Phase 380V VFD
VFD products recommended by ATO
I need a VFD recommendation. I have a 3 phase motor. I need to run off of 220v single phase and the motor name plate is listed as follows 1725 rpm 208-230/460 6.0/3.0 amps 60 hertz 2 HP. What do your recommend?

Ok, based on your motor specs, recommended drive model: GK3000-2S0022, 3hp capacity.
For my application I need to have maximal torque (that is why I chose to run in senseless vector control mode ). What settings do I need to get the maximum torque at low RPM for your 1-phase drives?

Our 1-phase driver is not suitable for running a single-phase motor under low speed and low voltage, which will lead to heating of single-phase motor. Generally, we suggest that the starting frequency should be set above 40Hz.
What is the correct way to ground the VFD?
I recently purchased a GK3000-CS0110G and I'm wondering what's the correct way to ground the unit.
The main earthing circuit terminal is not electrically connected to the earth plate at the back of the unit or to the PE grounding terminal on C2 terminal block on the PCB.
I would have expected all three to be electrically connected. Is this a defect? If not a defect, what is the correct way to ground the unit?

Regarding the correct grounding of the VFD, the grounding cable at the PE end must not borrow the grounding wire of other equipment and must be directly connected to the grounding plate.
The PE grounding terminal is mainly to prevent the internal leakage current of the VFD and is not directly connected to the internal PCB board. This grounding design is not questionable.
You just need to connect the VFDs and motor's grounds individually to the grounding panel.
Hope my explanation is able to assist you. Please feel free to let us know if you have any further questions.
