Abstract：The paper introduced the hardware and the software designed of the step-motor’
group control system based on NextMoveES Motion Control Card ,and CAN and RS-485 bus as the system’transmission line. The system made the best use of the merit of the CAN and RS-485 bus to realize the distance group control of step-motor. At the same time because of
NextMoveES’chip-DSP and FPGA，the real-time manage is enhanced．The control system
possesses the characteristics such as the structure is simple and the reliability is high and the
cost performance is high ect．So it has important reference value．
