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.
Claims13
A data processing system comprising:
- an acquisition part that acquires, as input values, at least one of a control value or a detection value, the control value being used for controlling a servo system including a load, a servo amplifier, and a servomotor that applies power to the load in accordance with control of the servo amplifier, the detection value being output from a sensor that detects a state of the servo system;
- and
- a generator that generates a diagnostic parameter used for deterioration diagnosis of at least one of the load or the servomotor based on extraction processing on the input values acquired by the acquisition part,
- the input values are values that are input for a predetermined period and vary with time, and
- in the extraction processing, the generator extracts, as the diagnostic parameter, an input value in a partial period of the predetermined period among the input values input for the predetermined period.
A data processing method comprising:
- acquiring, as input values, at least one of a control value and a detection value, the control value being used for controlling a servo system including a load, a servo amplifier, or a servomotor that applies power to the load in accordance with control of the servo amplifier, the detection value being output from a sensor that detects a state of the servo system;
- and
- generating a diagnostic parameter used for deterioration diagnosis of an object of at least one of the load or the servomotor by performing at least extraction processing on the input values,
- wherein
- the input values are values that vary with time, and
- in the extraction processing, a value in a partial period among the input values is extracted as the diagnostic parameter.
