Abstract: A drive control device having: a storage circuit configured to store a reference rotational speed table; a drive signal generation circuit configured to output a drive signal to the direct current motor; and a control circuit. When an absolute value of a difference between a second rotational speed corresponding to a first rotational direction and a third rotational speed corresponding to a second rotational direction is equal to or larger than a predetermined threshold, the control circuit creates separate rotational speed tables for the first rotational direction and the second rotational direction in which each rotational speed table indicates a relation between a rotational speed and an electric power amount per unit time, and determines an amount of electric power that is supplied to the direct current motor which corresponds to a designated rotational speed according to the rotational speed table selected in accordance with a designated rotational rotation.

Abstract: A motor control device has a communication unit that receives a control command comprising a motor type identification signal and a rotation signal, wherein the motor type identification signal indicates whether a control object motor is a stepping motor or a DC motor, and wherein the rotation signal designates a target rotation amount and a target rotation speed of the motor, a sensor interface that receives a detection signal from a rotation angle sensor when the control object motor is the DC motor, wherein the rotation angle sensor outputs the detection signal every time the motor rotates by a first rotation angle, a DC motor drive signal generator that generates and outputs a first drive signal rotating the DC motor at the target rotation speed, and a stepping motor drive signal generator that generates and outputs a second drive signal rotating the stepping motor at the target rotation speed.

Abstract: A drive control system has: a plurality of drive control devices; and an upper-level control device to which each of the drive control devices is connected in parallel with each other via a common signal line. The upper-level control device transmits a common information acquirement request signal to each of the drive control devices. Upon receiving the information acquirement request signal, each of the drive control devices determines transmission start timing for a response signal based on transmission sequence information indicating its transmission sequence and a length of the response signal such that the response signal does not temporally overlap with a response signal being transmitted from another drive control device to the upper-level control device. Each of the drive control devices transmits the response signal to the upper-level control device via the signal line at its transmission starting timing.
