An002-Control a Clean Power VFD with PLC using Modbus TCP

In this application note, we will explore the integration of the Clean Power Variable Frequency Drive (VFD) with a Programmable Logic Controller (PLC) using Modbus TCP

The Clean Power VFD is a highly efficient product designed to control motor speed and torque by producing a pure sine wave, which helps to minimize harmonic distortion and improve the lifespan of equipment.

Modbus TCP is a robust protocol widely used in industrial automation for communication between devices such as PLCs and VFDs. It allows for efficient and reliable data exchange over Ethernet networks.

This guide aims to demonstrate how to control motor speed, manage the direction of rotation, and monitor alarm statuses using Modbus TCP communication between a PLC and a Clean Power VFD.
