Servo Control Device Visualizing Single-Axis Precision via Virtual Orthogonal Axes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for adjusting servo systems with single control axes, such as straight line or rotation axes without adjacent orthogonal axes, lack a visual evaluation standard, leading to decreased work efficiency and increased adjustment costs, as they require actual work processes for precision evaluation.
Innovation Solution
A control device and method that instructs periodic position instructions, records and draws position feedback data on a two-dimensional plane with orthogonal axes, allowing for visual adjustment by converting position data before or after a quarter cycle, enabling the servo system to be adjusted similar to conventional orthogonal two-axis systems.

Engineering Contradiction Analysis
1Measurement precision
If a work process is actually carried out to evaluate processing precision for single control axis servo systems, then measurement precision is improved, but productivity deteriorates and loss of time increases
Solution Approach 1:
The patent creates a virtual two-dimensional coordinate system that copies the evaluation methodology used for multi-axis systems. By generating synthetic X and Y axis data from a single axis position feedback signal, it replicates the arc instruction evaluation environment without requiring actual multi-axis hardware or production work processes.
Solution Approach 2:
The patent transforms one-dimensional position feedback data into a two-dimensional evaluation space by creating virtual orthogonal axes. This dimensional transformation allows the application of two-dimensional arc instruction evaluation methods to single-axis systems, enabling visual track shape analysis without additional physical axes.
2Measurement precision
If a work process is actually carried out to evaluate processing precision for single control axis servo systems, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent creates a virtual two-dimensional coordinate system that copies the evaluation methodology used for multi-axis systems. By generating synthetic X and Y axis data from a single axis position feedback signal, it replicates the arc instruction evaluation environment without requiring actual multi-axis hardware or production work processes.
Solution Approach 2:
The patent prepares the evaluation environment in advance by creating virtual orthogonal axes and establishing the two-dimensional coordinate system before actual servo adjustment begins. This preliminary setup allows immediate visual evaluation once position feedback data is obtained, eliminating the need to perform actual work processes during the adjustment phase.
3Device complexity
If visual evaluation standard is not present for single control axis servo systems, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The patent makes the evaluation system universal by creating a methodology that works for both multi-axis and single-axis servo systems. The virtual two-dimensional coordinate system and arc instruction evaluation method can be applied regardless of whether the physical system has one axis or multiple axes, providing a unified adjustment approach.
Solution Approach 2:
The patent introduces a virtual two-dimensional coordinate system as an intermediary between the single-axis physical system and the evaluation process. This virtual environment mediates the evaluation by transforming single-axis feedback into two-dimensional track data, enabling visual assessment without requiring physical multi-axis hardware.

AI summary
A servo control device that displays, by a two-dimensional image, evaluation of control precision of a servo system, includes: an instruction unit that instructs a position instruction having periodicity; a unit that records a track of position data based on a position feedback of a servo system according to the position instruction; and a first drawing unit that draws position data based on the position feedback, data before a quarter cycle or after a quarter cycle of the position data or position data based on the position instruction before a quarter cycle or after a quarter cycle, on a two-dimensional plane including orthogonal two axes, as the axis data of the orthogonal two axes respectively.
