VFD Variable Frequency Drive 220V 2.2KW Input 3 Phases to Output 3 Phases

The HS320/321 series variable frequency drive is a general-purpose inverter developed for various fields, including traditional agriculture, industry, and manufacturing. It is widely applicable in industries such as fans, pumps, printing and packaging, power materials, metallurgy, chemicals, and municipal fire protection. This series of frequency inverters features outstanding performance, rich functionalities, compact structure, simple operation, safety and reliability, and excellent adaptability to different environments.

Variable Frequency Drive Features

1. This series VFD equipped with open-loop vector drive function, capable of handling applications requiring low speed and high torque.

2. The variable frequency drive features a completely sealed cooling air duct, providing strong environment resistance and excellent heat dissipation performance.

3. HS320/321 frequency converter includes V/F control It provides high torque output and strong ability for loaded start-up.

4. It's very User-friendly and suitable for multi-scenario applications (such as intelligent small water pumps, engraving machines, etc.)

5. Our variable frequency drive has comprehensive protection functions, including output phase loss protection, overcurrent protection, overvoltage protection, overload protection, and over-temperature protection.

6. The HS321 series VFD adds functions such as braking, RS485MODBUS communication functions, and temperature protection on the basis of HS320.

Installation and Wiring

VFD-HS320 Functional Parameters

Commissioning and operating

(1) Operation panel and operation method

Method of returning to the original interface after setting parameters: 

 1. Power off and then power on again. 

 2. Select d-00 and press SET. 

 3. Long press  the SET key.

(2)Set the run command mode of frequency

The run command mode of frequency converter is set by parameter F0.02: Thereare two start-stop modes: panel control start-stop mode and terminal control start-stop mode:

①Panel control start-stop mode: (Factory setting for panel start-stop is F0.02=0)

To use the panel control start-stop frequency converter, press the green button on the panel to start, and the red button to stop. The converter starts with forward run by default, and the forward or reverse run needs to be set through the input terminal X1-X5 (the reverse setting is 4).

②Terminal control start-stop mode: (Factory settingfor terminal start-stop is F0.02=1)

(3)Selection of frequency setting mode of

The frequency setting mode of the converter is set by parameter F0.03. When F0.03=4, the running frequency is set by potentiometer; When F0.03=2, the running frequency is input by AVI (0-10V potentiometer can be connected externally); When F0.03=3, the running frequency is input by ACI (4-20mA); When F0.03=1, it is controlled by the external terminal (the switching value is set to be increasing/decreasing frequency).
