Abstract: Aiming at the problems of some functional redundancy of motor in control system and flexible production in industrial automation lines, and studying on the control system of multi motor coordination such as industrial manipulator, packing machine, casting machine, a control system for masterslave multiaxis motor based on DeviceNet field bus technology was put forward. Modular programmable logic controller (PLC) was used in control system to improve the relative independence, interchangeability and versatility of system. At the same time the system was controlled by master connection mode to optimize the system control, simplify the master design and increase system reliability. The multiaxis motor control system platform and NBDesigner were used to test precision errors repetitively for different motor running. The running results indicate that stepper motor can replace the servo motor to complete different control needs when it meet the operating characteristics and precision requirements. This system with different motors has better economic benefits, and it has practical application value in the production of industrial automation.
