Patent Images
1. A control parameter automatic adjustment apparatus which adjusts a control parameter of a servo system including a drive system and a controller for controlling the drive system, the control parameter automatic adjustment apparatus comprising:
- a parameter acquisition unit which acquires a movable range parameter of a drive shaft of the drive system;
a test movement program generator which generates a test movement program based on the movable range parameter acquired;
an operation data acquisition unit which acquires information on how the drive system is operating when the drive system is operated using the test movement program;
an operation data analyzer which analyzes the information acquired; and
a parameter adjuster which adjusts the control parameter of the servo system based on analysis by the operation data analyzer of the information acquired, wherein the control parameter is a friction parameter of the drive system.

Abstract
A control parameter automatic adjustment apparatus acquires a movable range of a drive shaft of a drive system, and automatically generates a test movement program to automatically adjust a control parameter to the drive system even though the movable range changes.
