Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional capacity selection tools for drive devices, such as servomotors, do not allow easy adjustment of parameters like moving amount, which affects the positioning operation and require repetitive user input, making the process time-consuming.
Innovation Solution
A parameter selection support system that includes a display unit, reception unit, and controller to calculate and display allowable ranges for operation pattern and mechanical condition parameters, allowing users to easily set parameters including moving amount based on the drive device's capacity.

Engineering Contradiction Analysis
1Measurement precision
If conventional capacity selection tools are used to determine motor capacity based on operation pattern and mechanical condition parameters, then the motor capacity can be calculated, but users need to repeat the operation of entering parameters multiple times when they want to review allowable parameters for a selected capacity, which is time-consuming
Solution Approach 1:
The system pre-calculates and stores allowable parameter ranges for different motor capacities before the user needs them. When a user selects a motor capacity, the system has already prepared the corresponding allowable operation pattern and mechanical condition parameters, eliminating the need for repeated calculations and reducing time loss.
Solution Approach 2:
The system dynamically switches between two operational modes: in the first mode, it calculates required capacity based on user-input parameters; in the second mode, it displays allowable parameters based on a pre-selected capacity. This dynamic adaptation allows the system to serve different user needs efficiently without repeated calculations.
2Power
If conventional tools only show magnitude of capacity based on acceleration time, deceleration time, and maximum speed, then capacity can be determined, but positioning operation parameters like moving amount and constant speed maintenance time cannot be adjusted or considered
Solution Approach 1:
The system expands the parameter set from traditional three parameters (acceleration time, deceleration time, maximum speed) to include positioning-specific parameters such as moving amount, constant speed maintenance time, and operation cycle time. By changing and expanding the parameter space, the system achieves both accurate capacity determination and comprehensive positioning operation control.
Solution Approach 2:
The system segments the parameter selection process into distinct controllable elements: operation pattern parameters (moving amount, speeds, times) and mechanical condition parameters (load mass, moment of inertia). This segmentation allows users to independently adjust each parameter to optimize positioning operations while maintaining overall system compatibility.

AI summary
A parameter selection support system that supports, based on a capacity of a drive device, selection of parameters of an operation pattern and parameters of mechanical condition for a load that is driven by the drive device and includes a display unit that displays an input screen for the parameters, a reception unit that receives the parameters and the capacity, and a controller that calculates an allowable range for each of some of the parameters that is allowable for the capacity received by the reception unit and causes the display unit to display the allowable range on the input screen. The parameters of the operation pattern include a moving amount of the load.
