How to Set Up 1 Phase to 3 Phase VFD for Conditional Auto-Start/Stop

2 months ago
#383 Quote
We have purchased a 20HP Single Phase to Three Phase VFD model GK3000 and we need assistance setting up parameters for it to turn on and off by itself. We would like it to turn on if VI to GND is between 0.5V to 1V and if there is a 0-10v signal to X2 and ground. If both these conditions are met then it would turn on and if the VI voltage goes out of range or if the X2 to ground loses signal we would want to turn it off.
We thought I had configured it properly but it won't turn on by itself like expected.
Any help would be much appreciated, thank you!

Hi Daniel, the X2 terminal and GND do not accept a 0-10V signal directly—it only works with dry contacts connected to COM. You should use the FWD-COM terminals for start/stop control.

Thanks for your response. We also want to know if is there no way to turn the VFD on when the 0-10v requirement is met PLUS an additional signal. And, turn it off when one of those is not met?

For VFD terminal control, you can refer to our demo video, see: https://www.youtube.com/watch?v=nBUm4i9wnzY&list=PLlo8RulDRnthBFbP4ydheukDSKw2hAfDn&index=12
