Title:
MOTOR CONTROL DEVICE AND MOTOR CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2024/079786
Kind Code:
A1
Abstract:
The present invention reduces a torque command according to a motor control state. A motor control device of a motor for driving the shaft of a machine is equipped with: a command generation unit for generating a motor movement command and determining an operation mode; a detection unit for detecting the location and/or speed of the shaft; a control unit for generating a torque command on the basis of the movement command and location deviation and/or speed deviation calculated from a detected value from the detection unit; and a determination unit for determining it is possible to reduce the torque command when the movement command, the operation mode and the location deviation and/or speed deviation each satisfy established conditions.
