Solution Overview
Problem
Existing multi-axis control systems face challenges in efficiently adjusting control parameters across multiple axes, particularly when axes are mechanically constrained or not, leading to issues with vibration and oscillation, which can damage machinery and affect synchronization accuracy.
Innovation Solution
A multi-axis control adjustment apparatus and method that includes an adjustment axis selection unit, an adjustment operation execution unit, and a first control parameter setting unit, allowing for synchronized adjustment operations and timing changes of control parameters across multiple axes, whether mechanically constrained or not, using a parameter adjustment apparatus connected to servo amplifiers and a host controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If control parameters are adjusted for multiple axes simultaneously in existing multi-axis control systems, then adjustment efficiency is improved, but vibration and oscillation occur causing machinery damage and synchronization accuracy degradation
Solution Approach 1:
The patent segments the multi-axis control adjustment into individual axis adjustments rather than simultaneous adjustment. The control parameter adjustment apparatus adjusts control parameters for each axis separately through a unified interface, preventing the vibration and oscillation that occurs with simultaneous adjustment while maintaining high adjustment efficiency through batch processing capability.
2Reliability
If control parameters are adjusted individually for each axis, then vibration and oscillation are prevented, but adjustment time and operational complexity increase
Solution Approach 1:
The patent merges multiple individual axis adjustment operations into a unified control parameter adjustment apparatus. The system provides a single adjustment interface that can process control parameters for multiple axes in sequence, combining the benefits of individual axis adjustment (vibration prevention) with efficient batch processing (reduced adjustment time).
Solution Approach 2:
The adjustment apparatus maintains continuous operation by automatically proceeding through each axis adjustment without requiring manual intervention between axes. The system continuously adjusts control parameters for each axis in sequence, eliminating idle time and manual reconfiguration while maintaining the reliability of individual axis adjustment.
3Ease of operation
If a unified adjustment interface is provided for multiple axes, then ease of operation is improved, but the complexity of managing different axis configurations increases
Solution Approach 1:
The control parameter adjustment apparatus implements a universal adjustment interface that can handle different axis configurations (mechanically constrained and non-constrained axes) through the same operation mode. The system automatically adapts to different axis types without requiring different adjustment procedures, simplifying operation while managing configuration complexity through automatic detection and adaptation.
