摘要： A PWM signal generation unit generates a PWM signal to drive a motor, based on a current value of the motor sampled by a current value sampling unit, a position or speed of the motor sampled by a motor sampling unit, and a position or speed of a driven object sampled by a driven object sampling unit. An operation stop unit stops the operation of any one of the motor sampling unit and the driven object sampling unit depending on the power stored in the DC link part and power to which the control power source can supply when the alternating-current power source fails.

摘要： To provide a motor drive device that suppresses voltage fluctuation of a DC link capacitor, as well as enabling for low cost and size reduction. A motor control unit sets a threshold of voltage at which to start regeneration to a first threshold in a case of an increased amount per unit time of a DC voltage value detected by a voltage detection part being less than a certain amount, and sets the threshold of voltage at which to start regeneration to a second threshold that is larger than the first threshold, in a case of the increased amount per unit time of the DC voltage value detected by the voltage detection part being at least a certain amount.

摘要： An attachment capable of preventing liquid from adhering to a specific electronic component within an electronic device. An electronic substrate has an attachment which can be attached to and detached from the electronic substrate. The attachment has an attachment part detachably attached to an edge of the electronic substrate; and a shield part connected to or integrally formed with the attachment part. The attachment part is a clip-like member having a certain degree of elasticity, and is configured to grip an edge of the electronic substrate so that the attachment is held at a predetermined place. The shield part has an inclined surface, and is configured to shield the electronic component so that liquid, such as a splash or droplet moving toward the electronic component, does not adhere to the component when the attachment is held at the predetermined place.
