How should the function P3.46 be set with those 3 digits?
Our plan is to put the function P3.46 = 1 (REV running mode) and to deactivate the Reverse with P0.04 = 10 (Running forward/Reverse prohibited). However, the function P3.46 on the VFD screen is showing a wider range of choice that is not mentioned on the manual. The screen is showing 3 digits. The first 2 digits go from 00 to 19 and the third one change only between 0 and 1. How should the function P3.46 be set with those 3 digits?

If you want to set P3.46=031
1. Ones place is used to select the way to use the keyboard JOG/REV key. So 1=REV.
2. Tens place is used to set the display parameters of the second row of digital tubes. Among them, 0~15 correspond to the monitoring parameters b-01~b-15 respectively. For example, if the user wants to always display the output current value in the stop state, set P3.46=3X, and the inverter will always display the output current value.
3. Hundreds place can be ignored. So P3.46=031.
Is there a way to prevent an error from stopping the VFD?
As requested, here is a video of the input voltage. The system error was an 07 (over voltage). Is there a way to prevent an error from stopping the VFD from operating when controlled by an external input? I will be 18 hours from this location, and if the VFD prevents the system from running, it will destroy a $200,000 area and 4 acres of new grass.

We received your video. The attached video shows that the VFD input voltage is about 246V, which is relatively high. If the input voltage fluctuates to about 250V, the VFD will generate overvoltage protection.
1. Please try to set the VFD overvoltage protection threshold P9.11=400V, and then observe whether there is still overvoltage phenomenon. We suggest that you control the input voltage below 240V.
2. The VFD has a fault automatic recovery setting. Please set P5.09=10 (fault recovery times), P5.10=5 (fault recovery time 5 seconds). Note: Some faults are irrecoverable, and you must set the VFD to start running automatically after power is restored.
How to wire the VFD for external frequency control?
Another question, how do I wire up the VFD for external frequency control?
External potentiometer (spec)? How about external Up/Down frequency control?
What are connections and program the settings?

1. Regarding the resistance value of the external potentiometer, we recommend 4.7K-10KΩ.
2. Regarding VFD using an external potentiometer to control the frequency, you can refer to our demo video, please see on: https://www.youtube.com/watch?v=TJsN1gW8hVQ&list=PLlo8RulDRnthBFbP4ydheukDSKw2hAfDn&index=11
Settings that change on the VFD drive
We connected the drive directly to the motor and started the system.
The motor starts up but only for few seconds. After that, the frequency dropped.
See below the video:

Can you please have a look and let us know if you see a settings that we should change on the drive.
See attached the changes already done.

1. First of all, please send your motor nameplate label including the motor wiring diagram.
We want to confirm whether your three-phase motor wiring is correct and is it connected according to the three-phase 380V voltage.
2. When testing the motor, please do not use the VFD to automatically start the running mode.
You should adjust the VFD parameters and use the automatic operation function after the manual operation is normal.
3. Please try to modify the parameters: p0.22=2 or 3, p0.17=15, p0.18=15, and test again.
For the parameter setting of this VFD, you can refer to the demonstration video: https://www.youtube.com/watch?v=XayY-s6XpZE&list=PLlo8RulDRnthBFbP4ydheukDSKw2hAfDn&index=26
Is there any specific parameter specifications for that VFD?
Is the frequency suppose to be a stable 50Hz at the output? From the tests that we did, the frequency is showing higher or just fluctuating too much to have a good reading. We’ll continue testing with the instruction that you send us within the last email.
Let us know if there’s any specific parameter specifications for that model.

We confirm that your order number is 944725. The model GK3000-CS0037 you bought is a customized version, input single-phase 220V, output three-phase 380V. You can continue to test, and we have provided you with the method in the last email. Please feel free to contact us if you have other questions.
After the frequency output of the VFD reaches the set target frequency (such as 50/60HZ), it is generally stable without much fluctuation. If there is any question, you can send the video to us for reference. You can send us the large video file via wetransfer.com.
Suggestions about VFD voltage and output testing
How would you recommend testing the output on the VFD for the voltage and the frequency?
By changing the frequency or the voltage output with the parameters, we’re not able to see any changes at the output.
We don’t want to connect anything before making sure that we have the right measurements on the output.
We want to make sure of other things too, we’re trying to connect 220V single-phase/50 Hz to the VFD to have an output of 3-phases/50Hz.
The manual says that this model (GK3000-CS0037) is made for an input 220V 3-phases.
Also, the terminal showed in the manual doesn’t match the ones on the VFD.
I believe the one that we receive has been converted to match our needs since it came without a terminal screw on the “S” terminal (see picture). I need a confirmation of how should the 220V/50Hz single phase should be connected and how to verify the output.

1. What is your order number? The model GK3000-CS0037 you bought is a version with single-phase 220V input and three-phase 380V output. We need your order number to check the specific parameter specifications.
2. About wiring: single-phase 220V is connected to the R-T terminal, and the S terminal is not used. The UVW terminal is the output terminal, which connects to your 3-phase motor.
3. About testing the voltage and frequency output on the VFD: Please set the basic parameters of the VFD when it is no-load, and then run the VD with no load to check whether the VFD can run to 50/60HZ. Then use a multimeter to measure the voltage of the output terminal to check whether it is the voltage you set (P0.08 sets the output voltage). You can refer to these two videos: https://www.youtube.com/watch?v=5w6imIrlYKs&list=PLlo8RulDRnthBFbP4ydheukDSKw2hAfDn&index=25 and https://www.youtube.com/watch?v=XayY-s6XpZE&list=PLlo8RulDRnthBFbP4ydheukDSKw2hAfDn&index=26
I would like to use the existing safety switches and motor to control 5HP VFD
I would like to use the existing safety switches and motor to control 5HP VFD. Do the Rev and fwd terminals require closed circuit voltage continuously to operate, or does momentary cause it to run indefinitely? Can I use the P24 terminal to run through the existing motor controls to operate the Rev and fwd functions?

Our single to three-phase 5HP VFD does not support direct connection of external control voltage, it can only be connected to COM through the internal control signal terminal.
I have 1-phase (L, N, G), 220V supply, and want to run split phase (L1, L2 G), 220V motor, so can I use GK3000-1S0004 drive?

The motor I have is on an old wood shaper from the year 1941. The 3450 rpm motor is pulley to create 8500 at the working end of the cutting tool, I want to spin it to aprx 14,000 RPM, can I use your VFD?

No, the motor should be VFD duty rated in order to be connected with the VFD.
