Abstract: Motor control system includes controller, motor control device, and position detection device. In controller, an operation command plan for a movement plan during a period until moving part reaches a target position from an initial position is set. Controller outputs, as an operation command, a movement amount of the moving part at a current point in time based on the operation command plan. Motor control device generates a drive signal for drive device based on an operation command Position detection device detects a position of moving part, and outputs a first position. Motor control device generates a deviation amount of moving part from the target position based on a future movement distance of moving part based on a future operation command, the first position, and the target position. Motor control device outputs a notification signal in a case where the deviation amount is more than or equal to a threshold.

Abstract: Convenience in deterioration diagnosis of servo system is enhanced. A diagnosis parameter used for the deterioration diagnosis includes at least one of a control value used for controlling servo system, a detection value output from sensor that detects a state of servo system, and a generation value generated from the control value or the detection value. Data processing system includes acquisition part, reliability determination part, and a reliability output part acquires the diagnostic parameter. Reliability determination part gives information regarding reliability of the diagnostic parameter to the diagnostic parameter. The reliability output part outputs the information regarding the reliability to a presentation device (display device) in association with the diagnostic parameter.

Abstract: An object is to make it easy to intuitively understand a state of a drive system. Diagnosis system (1) diagnoses a specific state related to performance of drive system (A1) including mechanical mechanism (M1) driven by motor (62). Diagnosis system (1) includes first acquisition part (11), second acquisition part (12), arithmetic part (21), and output processor (22). First acquisition part (11) acquires specification information (D1) related to a specification of mechanical mechanism (M1). Second acquisition part (12) acquires actual measurement information (D2) related to a mechanical characteristic of mechanical mechanism (M1). Arithmetic part (21) calculates an index value associated with the specific state based on specification information (D1) and actual measurement information (D2). Output processor (22) outputs the index value in a mode in which the user can identify the specific state.

Abstract: Misleading is less likely to be caused in deterioration diagnosis of servo system. A data processing system includes acquisition part, first generator, second generator, and presentation part. Acquisition part acquires at least one of a control signal of servo system and a detection signal from sensor. First generator generates pieces of first data regarding three or more feature values from a predetermined region in a signal waveform. Second generator generates three or more pieces of second data indicating change tendencies with time of the pieces of first data regarding the three or more feature values. Presentation part compares the three or more pieces of second data with each other, and presents specific second data exhibiting a different change tendency by performing specific processing related to object data that is the first data that causes the different change tendency in a case where there is the specific second data.

Abstract: Motor control system (10) includes position detection device (14), controller (12), and motor control device (16). Motor control device (16) includes a shift amount calculation unit that calculates a predicted arrival position of moving unit (50) based on positional information indicating a position of moving unit (50) detected by using position detection device (14) and distance information indicating a future moving distance of moving unit (50) based on an operation command, calculates a shift amount between the predicted arrival position and a target position of moving unit (50), and outputs information indicating the shift amount between the predicted arrival position and the target position. The shift amount calculation unit determines a reference point in time in consideration of at least one of an acquisition time required to acquire the positional information and an acquisition time required to acquire the distance information, acquires or calculates the position and the future moving distance of moving unit (50) at the reference point in time, and calculates the predicted arrival position based on the position and the future moving distance of moving unit (50) at the reference point in time.

Abstract: Accuracy of deterioration diagnosis is improved. Data processing system (1) of servo system (7) includes acquisition part (2) and generator (3). Acquisition part (2) acquires, as input values, at least one of a control value and a detection value. Generator (3) generates a diagnostic parameter by performing at least extraction processing on the input value acquired by acquisition part (2). The diagnostic parameter is used for deterioration diagnosis of object (OB1) of at least one of load (73) and servomotor (72) in servo system (7). The input values are values that vary with time. In the extraction processing, generator (3) extracts, as a diagnostic parameter, a value in a partial period among the input values.
