Abstract: Aiming at solving the problems of conventional stepper motor integrated power drive chip, which are low driving current and complicated peripheral circuit; CPLD chip EPM240T100 was used as the core control chip, and TB6560 was used as the driver of stepping motor; the stepping motor control system based on EPM240T100 and TB6560 was devised. TB6560 integrated stepper motor driver chips, this series of functions were integrated in a chip, the drive current was improved, the freewheeling diode and other peripheral hardware circuit design were simplified, the motor drive module cost and stability were improved. CPLD chip I/O rich port resources were made full used; real-time control of four stepping motors was realized by the interface of four TB6560 stepping motor drive modules; the needs of practical application had been met. The results show that TB6550 is the stepper motor driver chip which has a broad application prospects. The whole system is verified in practical application, has completed the 4 stepper motor control products, has the very high application value.
