1Productivity
If manual selection of amplifiers from many types is performed, then selection accuracy can be maintained, but selection time and complexity increase significantly
Solution Approach 1:
The patent replaces manual amplifier selection with an automated calculation system that computes optimal amplifier combinations based on motor load data and operation programs. The selection device automatically calculates necessary amplifier capacities and presents optimal combinations, eliminating the need for manual evaluation of multiple amplifier types while maintaining selection accuracy.
Solution Approach 2:
The patent introduces an intermediary calculation system that acts as a mediator between motor specifications and amplifier selection. This system processes motor load data, operation programs, and amplifier characteristics to generate optimal amplifier combinations, simplifying the selection process for users while ensuring technical accuracy.
2Measurement precision
If detailed analysis of all amplifier specifications is performed, then optimal selection accuracy is maintained, but time consumption increases
Solution Approach 1:
The patent performs preliminary calculations of amplifier capacities based on motor specifications and operation programs before presenting selection options to users. The system pre-computes necessary amplifier capacities and generates optimal combinations in advance, allowing users to review pre-analyzed options rather than performing detailed analysis themselves, thus maintaining accuracy while reducing time consumption.
Solution Approach 2:
The patent substitutes manual detailed analysis with automated calculation that rapidly processes amplifier specifications and motor data. The calculation unit automatically evaluates amplifier capacities, power consumption, and other parameters to generate accurate selection recommendations, eliminating the time-consuming nature of manual detailed analysis while preserving selection precision.
