摘要： A step motor driving apparatus includes a micro control unit (MCU), a pulse generator, a first step motor driver, a second step motor driver, and a communication port. The first step motor driver is configured for driving a first step motor and connected to the MCU. The second step motor driver is configured for driving a second step motor and connected to the MCU. The MCU is connected to the second step motor driver via the pulse generator. The pulse generator is configured to supply pulse signals to the second step motor driver. The communication port is connected to the MCU. The MCU receives a corresponding command from an external control apparatus via the communication port. The MCU selectively controls the first step motor driver to drive the first step motor or controls the second step motor driver to drive the second step motor according to the command.
