Note:

The single phase motor should Not be adjusted to run based on a lower frequency than 80% of its rated frequency for along time, otherwise the motor may fail.
ATO VFD Cannot be used as a power source, it Can only be directly connected to an induction motor to control the motor speed.
Single phase VFD Cannot control the motor in reverse, if you want to reverse the motor, refer to the motor nameplate instructions for operation.

Tips: Variable frequency drive applications

Air conditioner load
Office buildings, shopping malls, supermarkets and some factories have central air conditioner. In the summer electricity peak, large city air conditioner power consumption accounted for more than 40% of peak power. Therefore, using variable frequency drive to drag the air conditioning system, refrigeration pumps, cold water pumps and fans is a very good energy-saving technology.
Crusher load
Metallurgical mines and building material industry use a lot of crushers and grinding mills, these machineries have significant effect using variable frequency drive.
Large furnace calciner furnace load
Metallurgy, building materials, caustic soda and other large industrial rotary kiln uses DC motor, commutator motor, slip motor, cascade speed control and medium frequency unit speed control before. Because of these speed control mode or a slip ring have low efficiency, in recent years, many companies use frequency control, the effect is excellent.
Compressor load
Low-pressure compressors are widely used in various industrial sectors, high-pressure high-capacity compressors has more applications in steel, mining, fertilizer, ethylene industries. Using frequency control will bring low starting current, energy saving, optimizing equipment and other advantages.
Rolling mill load
The metallurgical industry uses AC-DC-AC VFD, and the multi-rack aluminum rolling unit uses general-purpose VFD to meet the low-frequency load starting. The variable frequency drive has advantages of inter-rack synchronous operation, constant tension control, simple and reliable operation.
Winding engine load
Iron mill blast furnace hoist equipment requires smooth boot and brake, balance speed adjusting and high reliability. These machineries use cascade, DC or rotor string resistance speed mode with low efficiency and poor reliability before. But, using VFD instead of the old speed control mode can achieve the desired results.
Revolving furnace load
Using AC variable frequency drive to replace DC unit in revolving furnace will get simple, reliable and stable operation.
Roller load
Roller load is mostly used in the iron and steel metallurgy industry. Using AC motor frequency control can improve equipment reliability and stability.

Running a single phase motor with VFD

In this video, ATO will show you details about running a single phase motor on a VFD. It's important to note that there are two wiring methods for single phase motor connecting to ATO single phase VFD: wiring of removing motor capacitor & wiring of keeping motor capacitor. At first, you should choose the wiring method you needed, and then set basic parameters step by step.

Four Ways to Control VFD with PLC

This video introduces the main wiring methods between PLC and VFD, including digital control, analog control, serial communication and Ethernet connection. The choice of connection method depends on the specific application requirements, system complexity, cost considerations and the need for control accuracy and flexibility.

How to Choose a VFD for Your Motor?

In this video, we lay out a list of key factors that should guide you in choosing the right VFD for your motor or any other possible application.

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.

Single-phase Output VFD Controls Single-phase Motor Speed

This video shows the details of using a frequency converter to run a single-phase motor on a single-phase power supply. Including wiring, parameter setting, single-phase motor speed control, etc.

Some questions

Is it possible to configure my GK3000-1S0007 so as to execute FWD upon power up? Also, is there a way to have the up/down buttons set the frequency instead of the potentiometer?
