Motor control system, motor control device, and motor control method

A motor control system that controls an apparatus, the apparatus including a moving part, a drive device, and a motor, the system comprising:

• a controller;
• a motor control device;
• and
• a position detection device, wherein
• the controller includes a first signal processing circuit,
• the motor control device includes a second signal processing circuit,
• the controller receives, as an input, a movement plan during a period until the moving part reaches a target position from an initial position, sets an operation command plan based on the movement plan, inputs the operation command plan to the first signal processing circuit, and outputs, as an operation command, a movement amount of the moving part at a current point in time to the first signal processing circuit based on the operation command plan,
• the motor control device inputs the operation command to the second signal processing circuit, and causes the second signal processing circuit to generate a drive signal of the drive device that moves the moving part based on the operation command,
• the position detection device detects a position of the moving part, and outputs, as a first position, the detected position of the moving part, and
• the second signal processing circuit generates a deviation amount of the moving part between the first position and the target position based on a future movement distance of the moving part based on a future operation command in the operation command plan, the first position, and the target position, and outputs a notification signal in a case where the deviation amount is more than or equal to a predetermined threshold.
