Existing reviews of 3 hp VFD, Single Phase 120V Input, 1ph/3ph 220V Output
This single-phase VFD has quite complete functions. Anyway, I am looking for a wiring diagram to hook up an external potentiometer to control motor speed.

You can externally connect a potentiometer with a resistance of 4.7K~10KΩ and a power of 2W-10W. Please refer to the wiring diagram on page 8 of the user manual. The potentiometer is connected to AI1, 10V, and GND, and just set F0-03=2.
I was able to connect VFD to my controller successfully though is it possible to signal back to my controller if there is an error.
Also I’d like to add a breaking resistor to it though I couldn’t find anything in the manual about that.
How do I determine the resistance that I need for the breaking resistor?

The braking resistor used in this VFD model EM15-SP1S1-2d2 is 100w/70Ω.
The braking resistor is connected to the P+/PB terminal.
I get error code 40 now I went through all the setting and made sure they were right. Now I get a error 0040 .

VFD displays error code 40, which means The load is too heavy or locked- rotor occurs on the motor. Also, The frequency inverter model is of too small power class. If the VFD can run normally after removing the motor, it means that your motor load is too heavy and the VFD is overloaded. We recommend that you replace it with a VFD with a 5HP capacity.
Hi, I keep getting an error code 02 now when I start the motor. Can you get any ideas how to fix this?

Please follow the steps below to troubleshoot and provide us with feedback:
1. Since your motor has dual voltage 230V/460V, please confirm that your motor wiring is based on low voltage 230V.
2. Please check whether the VFD input voltage is 120VAC?
3. Please tell us what parameters are set in the VFD, especially whether the parameters F1-01~F1-04 are set according to the motor nameplate?
4. Please confirm that the VFD and motor are connected correctly and set the correct parameters, then run the VFD again and provide us with a start-up video for confirmation
Please give me more details of VFD
We currently have your drives installed with the motors in the attached picture. We were informed by you yesterday that these are the incorrect drives.
We are going to replace them with the drives you recommended (model EM15-SP1S1-2d2). Before we install these new drives, we would like for you to give us detailed step-by-step programming instructions.
We need this detailed info prior. Is this something you can help with?

So I wired my AC Variable frequency drive to my single phase 220V motor, on first start up it ran fine for about 3 or 4 min, and then the starting capacitor got hot and started to smoke, and a small mount of the oil came out of the capacitor. I believe what happened is the switch never engaged so I stayed on the start up windings. So it will run if I give it a little help getting it to spin, but that capacitor gets really hot. The centrifugal switch will not ingage until it is at about 75% rpms. And I am trying to run the motor at much slower speeds. Is it possible to bypass the centrifugal switch and the bad capacitor possibly? Is it safe to do so?

This is a problem with the characteristics of the single-phase motor itself, so we do not recommend that the single-phase motor run for a long time at low frequency and low speed, otherwise the motor capacitor will heat up. Because the starting capacitor of the single-phase motor is only used to assist the motor to start. If the motor runs at low speed for a long time and the centrifugal switch is not disengaged, it will cause heat damage to the motor. If you want the motor to run at low frequency and low speed, we suggest you use a three-phase motor, or you can try to change the internal winding circuit of your single-phase motor to three-phase wiring and remove the capacitor.
What's wrong with my 3hp VFD?
I got a problem with your drive, with a 3 phases motor the output voltage drop to 150 and without load it has 220. What's wrong?

The problem you mentioned is probably caused by the over load current driven by the motor is huge, and then the input voltage and bus bar voltage to be low. You can try to set F0-10=60, F0-12=60, F0-17=10, F0-18=10, then rerun the VFD and test again. When the VFD is running, you can switch the shift key >>U0-03 & U0-04, to see the voltage and current output from the VFD real-time. If the VFD cannot working properly, you may need to replace a larger capacity VFD.
I am trying to drive a custom solenoid at variable frequency. Curious to know if the output voltage of GK3000-SP1S1-2d2 is variable.

We recommend to use the drive with motors only. And yes, the output voltage is variable.
3hp VFD question answering
Do we still need to debate VFDs when used on single phase input power like we did with the older VFDs or have you done something like beefing up the input diodes and caps so they will be able to output the same power as on 3 Ph?

For our 1-phase To 3-phase drive, no need to oversize, we care about that in design, just consider 10% margine above rated output current referred at each model seen at our web site.
