Reference numeral 5 denotes an excitation method selection switch, which selectively determines the excitation method such as 4-phase excitation mode, 3-phase excitation mode, or 3-4 phase excitation mode in the case of a 4-phase stepping motor; In a phase stepping motor, one-phase excitation mode, two-phase excitation mode, or one to two-phase excitation mode is selectively switched. . Furthermore, a changeover switch 16 attached to the memory circuit 12 is for switching between driving the two-phase stepping motor and the four-phase stepping motor.

る。 The semiconductor memory circuit 12 is basically a memory for a four-phase stepping motor, but in the case of the present invention, it is configured by storing two circuits of excitation modes of a two-phase stepping motor. It is configured to be able to drive either one 4-phase stepping motor or two 2-phase stepping motors. That is, such a memory circuit 12 is
For example, unipolar 3 for 4-phase stepping motor
It is possible to configure a four-phase excitation mode as shown in FIG. 2, and a unipolar two-phase excitation mode for two-phase stepping motors as shown in FIG. 3.

回路に適用して最適なものがある。 According to such a configuration, in the case of the conventional method of driving two two-phase stepping motors, low-speed drive can be achieved with one drive circuit, but high-speed drive requires two separate drive circuits. However, in the present invention, the memory circuit 12 for the 4-phase stepping motor can be set to any excitation mode for the 4-phase stepping motor using a switch 16. Alternatively, it can also be used as the excitation mode for two two-phase stepping motors, making it possible to significantly reduce component costs and wiring man-hours, making it ideal for this type of stepping motor drive circuit. There are some that are best suited for application.
