The invention provides a multifunctional universal stepping motor driver. The multifunctional universal stepping motor driver comprises a single-phase driving circuit, a CPU and an interface circuit, multiple optocoupler isolating circuits, an on-off input signal acquisition circuit, an SSI signal acquisition signal and a CAN bus communication interface circuit. The CPU comprises the control process of reading the configuration information of the current working mode, invoking a corresponding data table, receiving CAN bus data, determining whether a control instruction is received, starting motor control, calculating a control speed and step number, determining a current output control value from the data table and completing time delay between steps and determining whether control is finished. The multifunctional universal stepping motor driver has the advantages that multiple subdivided control of the stepping motor and the closed-loop control of a specific control object are realized, the reliability of control is improved, and the universal stepping motor controller is convenient to use.
