Title:
MOTOR CONTROL SYSTEM, APPARATUS, AND DIAGNOSIS METHOD FOR INDUSTRIAL DEVICE
Document Type and Number:
Japanese Patent JP2020048410
Kind Code:
A
Abstract:
To mitigate a physical or processing-related cost in a motor control system.SOLUTION: An upper communication path (80) of a motor control system (1) connects an upper communication port (24A) of a motor control device (20) for controlling a motor with an upper controller (10) for transmitting an instruction to the motor control device (20). A lower communication path (90) is connected to a lower communication port (24C) of the motor control device (20), and the lower communication path connects, in series, a rotation angle detector (40) for detecting a rotation angle of the motor (30) with output apparatuses (50, 60, and 70) for outputting related information that differs from the rotation angle or related information that is related to an industrial apparatus related to the motor (30). The motor control device (20) executes predetermined processing on the basis of the rotation angle of the motor (30) and the related information acquired through the lower communication path (90), and transmits an execution result of the processing to the upper controller (10) through the upper communication path (80).SELECTED DRAWING: Figure 1
