PURPOSE:To realize rotation of a pulse motor synchronized with an external synchronizing signal having frequency in slew region deviating from a self- starting region. CONSTITUTION:A pulse motor 1 is started in a self-starting region with accelerating/decelerating pulses outputted from a pulse generator 4. When the pulse motor 1 is accelerated upto an external synchronizing signal 6, a switching circuit 3 is switched by a signal fed from a sequencer 5 and the pulse motor 1 is rotated with the external synchronizing signal 6. Consequently, the pulse motor 1 can be rotated with the external synchronizing signal 6 in a slew region which deviates from the self-starting region. |
