8 Modbus-RTU communication
The company provides users with the general RS485 communication interface in industrial control.
The communication protocol adopts MODBUS standard communication protocol, and the servo can be
used as the slave station to communicate with the master device (such as PLC controller and PC) with
the same communication interface and the same communication protocol, and the HMI can also be
connected through the communication interface. Realize the remote operation of the frequency
converter by the user.
This series of servo Modbus communication protocol supports RTU mode. The following is a
detailed description of the communication protocol.
