1Ease of manufacture
If control parameters are set based on constant mechanical parameters assumption, then existing setting technologies can be applied, but repetitive adjustment and evaluation is required when mechanical parameters vary with orientation
Solution Approach 1:
The system pre-calculates evaluation index values for multiple load device orientations before actual parameter setting. By performing preliminary evaluation calculations for various orientations (horizontal, vertical, intermediate positions), the system prepares assessment data in advance, eliminating the need for repetitive trial-and-adjustment cycles during actual parameter setting.
Solution Approach 2:
The system creates a virtual model of the load device's mechanical parameters across different orientations and copies the evaluation process to this virtual model. By calculating evaluation index values based on predetermined orientations without physical iteration, the system replicates the effect of actual testing while avoiding repetitive physical adjustment and measurement.
2Reliability
If control parameters are adjusted repeatedly to accommodate varying mechanical parameters, then control performance across orientations can be improved, but setting time and complexity increase
Solution Approach 1:
The system automatically calculates evaluation index values for multiple orientations and identifies optimal control parameters without requiring operator intervention for repetitive adjustments. The control parameter setting unit autonomously determines parameters that satisfy evaluation criteria across all predetermined orientations, enabling the system to self-optimize without increasing operational complexity.
Solution Approach 2:
The system changes the approach from iterative physical parameter adjustment to computational parameter optimization. By calculating evaluation index values based on different orientations and using these computed values to directly determine optimal parameters, the system transforms a complex iterative process into a streamlined computational procedure.
3Measurement precision
If evaluation is performed for each orientation separately, then control performance can be optimized for each state, but overall setting time increases
Solution Approach 1:
The system merges the evaluation process for multiple orientations into a single integrated calculation. By computing evaluation index values for horizontal, vertical, and intermediate orientations simultaneously based on unified mechanical parameter models, the system maintains precise evaluation for each orientation while achieving all evaluations in one operational cycle rather than through separate iterative processes.

AI summary
A setting support device according to the present invention is provided with: a first identification means that identifies an evaluation index value indicating the stability or control performance of motor control by a motor control device in each of a plurality of load device states in which a load device is in mutually different orientations or situations; a second identification means that identifies a combined evaluation index value representative of the evaluation index values for the plurality of load device states, identified by the first identification means, on the basis of the evaluation index values for the plurality of load device states; and a display control means that displays, on a screen of a display, the combined evaluation index value identified by the second identification means. This makes it possible to reduce the time needed for setting a parameter value in a motor control device that controls a motor that drives a load device in which a mechanical parameter changes depending on the orientation or the like.
