PURPOSE:To easily and stably perform the control of pulse motor, by picking up the output of parallel pulse train of the gray code generator with selection and synthesis at any time according to the content of entry of up down counter. CONSTITUTION:According to the objective drive 14, the value corresponding to the number of total pulses of the pulse motor 10 is set to the digital switch 1 and this set value enters the down counters 2, 3. When the motor 10 starts, this set value is decreased according to the actual number of revolutions and it is entried to the up down counter 6. The gray code generator 7 produces the pulse trains of a plurality not duplicated in parallel, and the pulse train outputs are suitably selected and synthesized according to the entry of the counter 6, and the output of the synthesizer 8 is smoothed with the down counter 9 to drive the motor 10. The content of entry is changed at any time with the content of the counters 2 and 3 for the counter 6, and the acceleration, equal speed and deceleration of pulse motor is made as required. |
