Tips: Universal VFD vs. single phase to three phase VFD

Universal VFD is a power control device that applies the principle of frequency conversion technology and microelectronics technology to control AC motor by changing the frequency of motor working power supply, converting AC power with fixed voltage and frequency into AC power with variable voltage or frequency. The process is to convert the frequency AC power into DC power through rectifier, and then convert the DC power into AC power with controllable frequency and voltage to supply the motor.

The single phase to three phase variable frequency drive is based on the ordinary VFD, which converts the 220V AC power into DC power through the rectifier (voltage doubling rectifier), and then converts the DC power into three-phase 380V AC power with controllable frequency and voltage to supply the motor. This method does not step up the voltage through the transformer, but only through the rectifier boost circuit, which greatly reduces the size and weight of the VFD, and the cost is lower compared to the boost device.

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

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.

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.

Control VFD with potentiometer & button (VI port)

ATO GK3000 vector VFD supports control of synchronous motors, and supports external potentiometer and button control.

This video is for ATO GK3000 upgrade version VFD 1-phase to 3-phase & 3-phase VFD (3-wire control/external terminal control mode).

Existing reviews of 20 hp VFD, 1-Phase 220V to 3-Phase 380V VFD

I am looking for some assistance to wiring a PLC to a VFD for motor control.

I watched the following video that you have controlled the motor by the PLC program.

ATO Responded

ATO VFD has a corresponding connection terminal to connect to the PLC analog signal input signal (4-20ma, 0-10V ). You can view the video on for details.https://www.youtube.com/watch?v=STnfr-ZoGWQ&list=PLlo8RulDRnthBFbP4ydheukDSKw2hAfDn&index=7, and the relay terminal TA/TB/TC of the VFD output can be connected to your PLC.
Looking forward to hearing from you.

Use of 20hp VFD

Could we use your 20hp VFD with solar and battery power?

ATO Responded

No, our 20hp VFD can not be used with batteries, nor solar, it can be used for AC supply only.
