PURPOSE:To readily and accurately control the speed of a stepping motor by storing a series of periods in memory means. CONSTITUTION:When a control is started, an address MAX for storing a period T0 corresponding to the initial speed is set to the internal register of a CPU1. The period T0 of the content of an address indicated by the register is set in a timer 3, and the timeup is waited. The timer 3 counts the clock signal and outputs a signal according to the set period. Accordingly, a coil A of a motor 6 is excited through a controller 4. Then, a period T1 of next address value of the MAX is set to the timer 3, and the timer 3 outputs an output of the period T1 at the timeup time. |
