Multi-Axis Servomotor Adjustment via Unified Trajectory Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing servo control systems face challenges in evaluating the appropriateness of parameter settings for multiple axes operating in cooperation, as the current methods struggle to effectively display and analyze the interrelated state of these axes.
Innovation Solution
The proposed solution involves a servomotor adjustment device that displays the transition of multiple associated control axes as target and control trajectories on the same time base, allowing for visual evaluation of followability and mechanical characteristics, such as local vibrations, thereby improving usability in evaluating the adjustment results of cooperating axes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple axes control states are displayed separately, then detailed analysis of each axis is possible, but evaluation of interrelated state of multiple axes becomes difficult
Solution Approach 1:
The patent combines multiple axes control state information into a single integrated display screen. The display shows control trajectories of multiple axes simultaneously with their time-base information, allowing users to evaluate the interrelated state of multiple axes in cooperation while maintaining the ability to analyze each axis individually through the unified interface.
2Manufacturing precision
If parameter adjustment is performed for each motor individually, then detailed optimization is achieved, but evaluation of multi-axis cooperation control becomes complex
Solution Approach 1:
The patent integrates the display of multiple axes control states into a single screen that shows all relevant information simultaneously. This includes control trajectories, time-base information, and measurement data for multiple axes, allowing users to evaluate multi-axis cooperation control results without needing to switch between multiple separate displays or perform complex manual analysis.
Solution Approach 2:
The patent adds a temporal dimension to the display by showing control trajectories with time-base information. This allows users to evaluate not only the spatial relationship between multiple axes but also their temporal coordination, providing a comprehensive view of multi-axis cooperation control performance in a unified display.

AI summary
To improve the usability so that the result of adjustment of a plurality of axes operating in cooperation is easily evaluated. An adjustment apparatus displays a graph indicating a temporal change of measurement data for each control axis and a control instruction on the same time base in a first area in a screen, and displays a control trajectory of a control position of each control axis, the control instruction, and a target trajectory of a target position in the screen.
