Note: ATO VFD Cannot be used as a power source, it Can only be directly connected to an induction motor to control the motor speed.

Tips: Variable frequency drive fault dynamic test method
The dynamic test can only be proceeding after the static test result is normal. Dynamic testing must note the following issues:

Before powering, the input voltage must be confirmed. If connect 380V power supply into 220V VFD, the VFD will be burned.
Check all the connections of the VFD to be correct connected and fastened. Improper connection may lead to failure, or seriously, to be burned.
After power on, check the failure display content, and initially determine the reasons.
If the fault is not displayed, first check whether the parameters are abnormal, and then reset the parameters, and start VFD to test U/V/W three-phase output voltage under no-load situation.
When the output voltage is normal and three-phase equilibrium, start load test. And it's best to start full load test.

How to Measure Circuits with a Digital Multimeter?

This video will show you how to measure electrical circuit using a digital multimeter.

VFD Two-Wire Control Wiring with Push Button for Forward Motor

In this video we've guided you through how to do VFD control wiring with a self-lock push button switch to run the motor in forward direction. We've covered everything from wiring to programming and even a test run. So just watch it through and hope you'll find it informative and helpful.

4-20mA speed Control on VFD

4-20mA is as common in analog control systems as 0~10V, and ATO GK3000 series VFDs are also perfectly compatible.

How to Control VFD with 0-10V (CI port)

This is port CI usage method for 0~10V to control the frequency of ATO GK3000 upgrade version. It is suitable for 1-phase, 1-phase to 3-phase, and 3-phase VFD.

VFD Analog Input 0-10V Frequency Control (VI Port)

ATO GK3000 VFD uses external voltage analog to control the frequency so as to achieve the purpose of motor speed regulation.
