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: A lot of money can be saved through VFD
Turning off only 10% of the fans and water pumps can save up to 25% of energy costs. In most systems, reducing its speed by 50% will result in a 75% reduction in energy consumption.
VFD helps your business operate more efficiently by using only the energy needed.
VFD extends the service life of equipment by reducing wear. Maintenance costs are also reduced.

This video includes three parts: 1. What is customized equipment? 2. Difference between non-enclosure and standard VFDs. 3. Pratical operation of ATO non-enclosure VFD. All above explains the features, functions and working of non-enclosure VFD.

In this video, ATO will show you the vfd basic troubleshooting guide.

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

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.

How to control multiple VFDs via Modbus

ATO VFD supports multi-unit linkage. In a short time, you don't have to turn on each VFD. You can start/stop/modify parameters at the same time with one key.

To what terminals can I do that?

I need to setup a pump dry float that will turn off the VFD. To what terminals can I do that?

ATO Responded

If your dry float has a normally open dry contact (NO), you can connect this dry contact to the X1 and COM terminals of the VFD. When the dry float has a signal, the normally open contact is closed, connecting the X1 and COM terminals, and the VFD stops. (Please set P4.00=11, define X1 terminal as stop signal)

I want to know some information about VFD

Hello, I have a drive EM15-SP1S1 input 120V single phase and output 240V 3 phases. I need to know the parameter to adjust the overcurrent protection and the detection time of overcurrent protection. Thank you.

ATO Responded

It is a pity that the overcurrent protection of this model is based on the hardware design (more than 2 times the rated current), so it cannot be set on the software. You can use it normally first. If there is any problem, please let us know.

According to our needs, you can buy your VFD?

We have a 5hp deep well pump. I would like soft start capabilities. Supply is 1 phase 220. If I purchase your single phase to 3 phase unit, can it be used with 3 phase input as just a vfd? If so, do any capabilities change.

ATO Responded

If your motor is rated at 3-phase, 208/220/230V, and its rated current is less than 20A, then you can use our 7.5hp drive, of model: GK3000-2S0055G.
