Explanation: A VFD’s Modbus communication function allows the VFD to communicate with other devices, such as PLCs, HMIs, or other controllers. Modbus is a popular industrial communication protocol that enables devices to exchange data with each other in a standardized format. By using Modbus communication, the VFD can be integrated into a larger control system and be controlled and monitored remotely. This function can be used for various purposes such as monitoring the VFD’s status, controlling the speed of the motor, reading parameters, and more.
