PURPOSE:To execute control with high position accuracy by removing the control mechanism of a mechanical type, replacing it with the constitution of an electric circuit, and selecting and switching, etc. a desired one out of plural speed control patterns set in advance. CONSTITUTION:A rotational position control device is constituted of a position commanding function generating means 1 consisting of a microcomputer, speed control pattern storing circuit part 2 which has stored plural speed control patterns I- in a ROM, pattern generating part 3, operation control board 4 and an operation control part 6 of a motor 100, etc. In this state, the speed control patterns are stored as a position signal (pulse train pattern) corresponding to a speed pattern, respectively, a desired control pattern is fetched in accordance with an instruction from the operation control board 4, and basing on a rotational position control command of the motor and a position output signal from an encoder 5, a speed control signal is generated by said function generating means 1 to drive and control the motor 100. |
