Title:
MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/155511
Kind Code:
A1
Abstract:
A motor control device comprising a motor control unit that, on the basis of an operation command signal for driving a motor and a feedback signal, from an encoder, corresponding to the operation of the motor, generates a command value pertaining to the operation of the motor in accordance with a prescribed feedback scheme so that the operation of the motor follows the operation command signal, wherein interrupt processing of a drive signal is executed by an interrupt unit on the basis of a comparison result of two items pertaining to a prescribed feedback value calculated using the feedback signal from the encoder, and to a state calculation value that is calculated on the basis of the operation command signal and that pertains to an operating state of the motor comparable with the prescribed feedback value. This configuration makes it possible to enhance the safety performance of the motor control device without being bound by the safety performance of the encoder.
