Phase conversion for 5hp motor
We are interested in the GK3000-2S0037G model VFD. Our application requires a typical 240V single phase connection for the input and three phase output of 240V to a 5 HP motor. I was looking in the manual and it indicated on page 21 that single phase is only applied to motors up to 3 hp (2.2 kW). Can you confirm that as indicated that the phase conversion will work for a 5HP motor, and if so what would the input connections look like as they apply to page 21 in the manual.

Generally, the capacity for VFDs in single phase input is 3 hp for small motors, just as you saw in the user manual.
This model is customized by a three phase input VFD to work for single phase input, which is absolutely worked for 5hp 3ph 240v motors.
GoHz can even customize a 10hp or 20hp VFD with single phase input to do the phase conversion job.

I realize that you have a 5hp VFD Mod# GK3000-2S0037;
Is this drive fully capable to operate a three phase 220 Volts; 60 Hz; 5 HP motor driving a hammer mill. The mill is to be connected to a Single Phase 220 volts 50 Hz Supply.
Would I need a bigger capacity vfd (say 10 Hp) for this application?
Please advise on the best option for this application.

Hammer mill is a heavy duty load, we recommend a 7.5hp VFD, GK3000-2S0055

Does 5hp pump require 7.5hp VFD
we will be running a 5hp high pressure pump for a reverse osmosis on a 220V single phase input. Will a 5hp VFD be sufficient or do we need to bump up to a 7.5?

VFD for 5hp high pressure pump
Yes, you can use this 5HP single phase to three phase VFD to drive the pump.

Good morning,
We have some jobsite heaters with an onboard 7KW diesel genset providing 240VAC single phase power to a heating unit with a 5HP three phase motor via a VFD. The VFD is used to provide soft-starting for the heater's blower motor and is also used to select 38HZ, 48HZ, or 58HZ frequency output for blower motor speed control.
The blower motor VFD is triggered by a temperature sensor on the heater housing to turn the motor on once a certain temperature is reached and then to turn the motor off again when the heater burner is turned off and the heater enclosure cools down to a certain temperature.
The heating unit is equipped with a rotary three detent speed control switch to select from the 38, 48, or 58HZ motor speeds.
For comparison's sake the VFD currently being used is an AC Lenze model Y250S.
Thank you.

Hello Scott, Yes, GoHz VFD will be a great replacement of your existing VFD. Output frequency is vary from 0Hz to 400Hz, you can control the motor on/off by sending the signal from the temperature sensor to GoHz VFD, contact us for more information.

I am received this 5hp VFD, and have a question for wiring from 220 V 1 ph to the 220 V 3 ph output. Where do I ground this? What terminal? Is that what the “E” terminal?

Does this VFD do phase conversion?
I have a 60Hz 3KW 220V 1170RPM 3 phase electric motor that's supposed to drive a device in my shop. I have a 220V single phase power. Does this VFD do phase conversion from 3 to single? Can it take single phase Input voltage @ 220V and they supply balanced 3 phase to my motor?

Does this VFD do phase conversion?
Yes, this 5 hp VFD can convert single phase 220v input to three phase output, to drive your 3kW motor.

External Wireless start Stop Control
Is it possible to use a wireless external start-stop control with this VFD? If so what would be the needed switch requirements and what would be the terminal connections? Would like to operate a dust collector from a wireless remote control.
Thanks
Steve

External Wireless start Stop Control
Hi Steve, The VFD can be controlled start/stop via terminals FWD & COM, as long as the external wireless switch transfers signal to the VFD, it's ok.

I purchased one of the 5HP VFD's intending to power another machine, but recently acquired a 5HP spindle CNC. I've been looking at rotary phase converters, but thought maybe this VFD would power the entire CNC.
I could rewire the CNC to have the VFD power only the motor, but would prefer to have the VFD power the entire system, would this work? Are there additional considerations?

I am wondering which is the ground terminal for the 220V input. I see the ground for the 3 phase output E but no E for the input. The terminals order is:
PB R S T P+ P- U V W E

I've purchased and installed 12 of these so far, the first being around three years ago and the most recent one was this month. These are being used to control blower motor speed for industrial towable portable heaters. As such, they're run 24/7 and are powered by a single phase 7KW generator.
Original factory installed VFD on these machines is no longer available, so I tried one of these as a replacement. Operation and reliability has exceeded expectations - especially at this price point.
