PURPOSE:To reduce a resonance phenomenon of a rotating system in a stepping motor thereby to improve a stepout limit by generating a pulse train capable of avoiding a resonance region of the system, alternately arranging the pulse trains to form a new pulse train. CONSTITUTION:Hybrid pulse train data composed of first and second pulse train data generated by pulse train generating means 2 are stored in memory spaces designated by addressing means 3 in pulse train memory means 4. Hybrid pulse train data are read out at the time of driving a stepping motor 8, and fed to pulse output means 6. The pulse train data at this time is generated by a first pulse train of higher frequency than the pulse frequency capable of causing a resonance phenomenon and a second pulse data of low frequency, and the second pulse train data are inserted to the first pulse train data for a predetermined time to be newly formed. |
