This chapter describes the communication protocols supported by the VFD.

The VFD provides RS485 communication interfaces and adopts the master/slave communication based on the international standard Modbus communication protocol. You can implement centralized control (setting commands for controlling the VFD, modifying the running frequency and related function parameters, and monitoring the running status and fault information of the VFD) through PC/PLC, upper control computers, or other devices to meet specific application requirements.
