Safety Function Data Trace Control for Motor State Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in designating collection target data groups for data tracing functions in safety systems, requiring significant time and effort, especially when unfamiliar with the required data groups, leading to potential errors.
Innovation Solution
A control system that outputs data groups of collection candidates based on selected safety functions, including safety parameters, allowing users to automatically select tracing conditions and reduce the need for manual designation of data and parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users manually designate collection target data one by one for data tracing, then the data can be collected accurately, but the time and effort required increases significantly
Solution Approach 1:
The system pre-configures and stores multiple collection target data groups in advance, each associated with specific safety functions. When a user selects a safety function, the corresponding pre-configured data group is automatically retrieved and applied, eliminating the need for manual item-by-item designation while maintaining accurate data collection.
2Adaptability or versatility
If users manually designate collection target data groups, then specific data can be selected, but the complexity of the operation increases especially for users unfamiliar with required data
Solution Approach 1:
The system creates a universal interface where selecting a safety function automatically provides access to the appropriate collection target data group. This multi-functional approach allows the same selection mechanism to serve both novice users (who benefit from automation) and experienced users (who maintain selection flexibility), thereby improving ease of operation without sacrificing adaptability.
3Ease of operation
If users designate collection target data without guidance, then they can choose freely, but the risk of error operations increases
Solution Approach 1:
The system provides feedback by displaying the collection target data group that will be collected when a safety function is selected. This feedback mechanism allows users to verify the selected data group before execution, reducing the risk of error operations while maintaining selection freedom. The system shows what data will be collected based on the safety function choice, enabling users to confirm appropriateness.

AI summary
Provided is control system which can support a user with respect to the designation of a data group to be collected. The control system (1) includes: first and second controllers (100, 200); a drive device (300) which has a plurality of safety functions for a motor (400); a data trace module (154) which traces a state value for indicating an operation state of the motor (400); and a support device (500) which receives a setting of the data group to be collected including the state value. The support device (500) includes: a storage (510) which stores collection candidate information in which a data group of collection candidates is associated with a type of a safety function; and an output unit (508) which outputs, as the data group to be collected, the data group of collection candidates associated with one selected safety function.
