    10.1 What this chapter contains This chapter describes the communication protocol of TD310 series VFDs. The TD310 series VFDs provide RS485 communication interface. It adopts international standard ModBus communication protocol to perform master–slave communication. The user can realize centralized control through PC/PLC, upper control PC, etc. (set the control command, running frequency of the VFD, modify related function codes, monitor and control the operating state and fault information of the VFD and so on) to adapt specific application requirements.
  • Page 192 TD310 Series VFD Communication protocol 10.3.1 RS485 The interface of RS485 works on semiduplex and its data signal applies differential transmission which is called balance transmission, too. It uses twisted pairs, one of which is defined as A (+) and the other is defined as B (–).

If there is an interval time (more than 1.5 bytes) before the completion of the frame, the receiving device will renew the uncompleted message and suppose the next byte as the address field of the new message.
  • Page 196 TD310 Series VFD Communication protocol number of “1” in the data transmission is odd number or even number. When it is odd, the check byte is “0”, otherwise, the check byte is”1”. This method is used to stabilize the parity of the data.
