Can Bus, Motor Soft Starter

Soft-starter which is an inductive motor starting device, can decrease the starting current and optimize the starting property of a motor. The application of CANbus technology to soft-starter of motor is put forward firstly in this paper. A CANbus protocol communication module of soft-starter and a RS232/CAN interface converter have been developed in this paper. Because of the high reliability and sound real-time, the technology of CANbus ensures the run of motor in the control system. The sound extensability of CANbus is suitable for motor group network-based control specially. Using the soft-starter with Can interface , the developer can provide an appropriate solution for a complex motor control system.
