Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In encoder control systems, the timing of position information generation varies by encoder type, requiring individual adjustments for accurate position data correction, which is cumbersome and inefficient.
Innovation Solution
An encoder and encoder control system that includes a first reception unit for receiving position information requests, a position information generation unit that generates position information after a predetermined delay, and a first transmission unit that transmits position information generation timing information via serial communication, allowing for optimal correction of position data without requiring manual input of timing information when switching encoder types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If position information generation timing is fixed for each encoder type, then correction accuracy is improved, but device complexity and operation difficulty increase due to requiring individual adjustments for each encoder type
Solution Approach 1:
The encoder automatically transmits its own position information generation timing (delay time) to the control device without requiring manual configuration. This self-service approach eliminates the need for users to manually input timing parameters for different encoder types, reducing operational complexity while maintaining accurate correction capabilities.
Solution Approach 2:
The control device is designed to universally accept and process position information from multiple encoder types by automatically receiving and utilizing the delay time information transmitted by each encoder. This universal design allows the system to handle different encoder types without requiring type-specific configuration, reducing device complexity while maintaining measurement precision.
2Measurement precision
If manual input of position information generation timing is required for each encoder type, then correction accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The encoder automatically transmits its own position information generation timing (delay time) to the control device without requiring manual configuration. This self-service approach eliminates the need for users to manually input timing parameters for different encoder types, reducing operational complexity while maintaining accurate correction capabilities.
3Measurement precision
If position information is transmitted after fixed delay for each encoder type, then position data accuracy is improved, but loss of time increases due to communication delay
Solution Approach 1:
The encoder transmits its delay time information to the control device, creating a feedback loop that allows the control device to compensate for the communication delay. By receiving the actual delay time from the encoder and using it for correction calculations, the system maintains position data accuracy while accounting for the time loss during communication.

AI summary
An encoder according to an example of the present disclosure includes a first reception unit configured to receive a position information request signal for requesting position information on an object to be detected, a position information generation unit configured to generate the position information at a position information generation timing after a predetermined delay time elapses from when the position information request signal is received, and a first transmission unit configured to transmit the position information to the outside via serial communication. The first transmission unit is configured to transmit, at least once, position information generation timing information representing the predetermined delay time to the outside via serial communication.
