Abstract:Aimed at the disadvantage of the method of traditional servo motors’ motion and control, this article takes the industry sewing machine system as the object of study, and proposes one kind of two axle AC servo motion and control system based on the DSP. This system combines the motion control and the servo, and is used in the industry sewing machine to serve for the control section of subordinate machine. This motion control system can control 4 stepper motors(axes 1, axes 2, axes 3, axes 4) and two main axle motors of AC servo (axes A, axes B), simultaneity it has 16 photoelectric isolation inputs and outputs, 5 photoelectric isolation electro-magnet outputs, and 2 adjustable PWM led lamps used to driver output. This experiment indicates that the system is reliable, real-time, low cost, convenient installation and use.
