    摘要: A stepping motor driving device includes a table, a driving pulse control part, an interpolation number indicating part and a driving part. The table stores thinned data which is thinned from original data and designates a pulse width of a driving pulse relating to a slow-up control or a slow-down control of a stepping motor. The driving pulse control part sequentially reads the thinned data from the table at predetermined intervals, to interpolate the thinned data in accordance with a given interpolation number so as to generate interpolated data and to output the driving pulse with the pulse width designated by the thinned data or the interpolated data by sequentially using the thinned data and the interpolated date at predetermined intervals. The interpolation number indicating part indicates the interpolation number to the driving pulse control part. The driving part drives the stepping motor in accordance with the driving pulse.

    摘要: A drive controller of an instrument controls a stepping motor to rotate a pointer of the instrument attached to a rotation shaft of the stepping motor, the pointer rotatable between a zero scale position and a maximum scale position. The drive controller controls the stepping motor to perform a sweeping operation in which the pointer is swung from the zero scale position to the maximum scale position and returned back to the zero scale position, wherein the drive controller controls the stepping motor, during the sweeping operation, to accelerate to a predetermined speed by outputting a rated torque signal to the stepping motor and controls the stepping motor to rotate at the predetermined speed by outputting a decreased torque signal to the stepping motor, the decreased torque signal being lower than the rated torque signal.

    摘要: A voltage type inverter apparatus comprising a voltage correcting portion. The voltage correcting portion corrects a given voltage instruction based on a value generated by passing a direct current bus voltage detected value through a first degree delay filter. In decelerating a speed of the alternating current motor, the speed is decelerated in an overexcited state by multiplying the given voltage instruction by a set gain. Simultaneously, a time constant of the first degree delay filter is made larger than a time constant in a normal control state.
