Data processing system and data processing method

A data processing system that outputs a diagnostic parameter used for deterioration diagnosis of at least one of a load or a servomotor in a servo system, the servo system including the load, a servo amplifier, and the servomotor that applies power to the load in accordance with control of the servo amplifier,

• the diagnostic parameter including at least one of a control value to be used for controlling the servo system, a detection value output from a sensor that detects a state of the servo system, or a generation value generated from the control value or the detection value, the data processing system comprising:
• a display, and
• a processor configured to perform operations comprising:
• acquiring the diagnostic parameter;
• providing information regarding reliability of the diagnostic parameter with the diagnostic parameter;
• outputting, to the display, the diagnostic parameter to which the information regarding the reliability is given;
• and
• generating the generation value by performing at least one of processing of converting at least one of the control value and the detection value into a statistic and statistical analysis.
