Variable Frequency Drive with 3PH AC 380V Output and RS485 Interface

The Variable Frequency Drive (VFD) you have purchased is a versatile and reliable industrial automation component. Designed with your convenience and safety in mind, it offers a range of features to enhance its usability and performance.

The VFD is constructed using flame-retardant ABS material, making it impact and heat-resistant with excellent overall durability. Its power rating is 2.2 kW, making it suitable for a wide range of motor applications up to 2.2 kW. The input voltage is single-phase AC 220 V, 50/60 Hz, 13.5 A, while the output is three-phase AC 380 V, 0-300 Hz, 9 A.

To ensure a seamless and secure installation, the package includes the VFD unit and a user manual. Before wiring, it is crucial to confirm that the input power supply is switched off. The wiring operation should be carried out by professional electrical personnel to comply with safety standards.

The VFD is equipped with multiple protection features, including phase loss, constant torque, load loss, overload, overcurrent, short circuit, overvoltage, undervoltage, overheat, and stall protection. These safeguards help maintain the stability and reliability of the device, reducing the risk of damage or unexpected shutdowns.

The VFD also features a user-friendly interface with a humanized keyboard and a digital display screen, making it easy to operate and monitor the device's performance. The unique design ensures efficient heat dissipation, contributing to the VFD's longer lifespan.

Furthermore, the VFD offers a standard RS485 communication interface, allowing users to read and write functional parameters, read status parameters, and write control commands through a supervisory computer. During communication, the VFD operates in slave mode.

The internal components of the VFD are designed with a modular approach, enhancing the overall stability and reliability of the machine. The industrial-grade, flame-retardant ABS shell provides strong protection against impact and heat, ensuring a robust and well-protected system.

It is important to note that certain precautions must be observed during the installation and operation of the VFD. The grounding terminal must be properly connected, and the emergency stop circuit wiring should be checked for effective operation. The output lines of the VFD must not be connected to the housing or short-circuited. Additionally, the input power supply voltage must be consistent with the VFD's rated voltage, and voltage withstand tests should be avoided.

The VFD is designed with a reset and retry function, providing flexibility in the event of an alarm. However, it is crucial to ensure that the operation is cut off before resetting the alarm, as sudden restarts can pose a safety risk.

Lastly, the VFD requires careful handling, as the terminals carry high voltage, which can be extremely dangerous. Wiring and terminal disassembly should be performed only when the main circuit power supply is disconnected.
