Abstract
A servo control apparatus controls operation of a to-be-controlled object through execution of software based on control data and reference data. An operation-signal generating portion generates an operation signal having a frequency representing the operation of the to-be-controlled object. A clock-signal generating portion generates a clock signal having a frequency controlled in accordance with the control data. A counting portion measures a time corresponding to the period of the operation-pulse signal by counting pulses of the clock signal, and generates a count value. A controlling portion controls the operation of the to-be-controlled object through execution of software based on the count value and the reference data.
Claims6
A servo control apparatus, which controls operation of a to-be-controlled object through execution of software based on control data and reference data, said apparatus comprising:
- an operation-signal generating portion generating an operation signal having a frequency representing the sensed/detected operation of said to-be-controlled object;
- a clock-signal generating portion generating a clock signal having a frequency controlled in accordance with the control data;
- a counting portion measuring a time corresponding to the period of the operation signal by counting pulses of the clock signal, and generating a count value;
- and
- a controlling portion controlling the operation of said to-be-controlled object through execution of software based on the count value and the reference data.
An information storing apparatus comprising:
- a mechanism portion driving a storing medium;
- a detecting portion detecting a driving state of said mechanism portion and generating a monitor signal having a frequency representing the driving state of said mechanism portion;
- a servo control portion measuring a time corresponding to the period of the monitor signal by counting pulses of a predetermined clock signal, and controlling said mechanism portion in accordance with the result of the measurement so as to cause the driving state of said mechanism portion to become a predetermined state;
- and
- a clock-signal generating portion generating a clock signal having a frequency controlled in accordance with control data, and providing the clock signal as the predetermined clock signal to said servo. control portion.
