Title:
電動機制御装置、および、空転或いは滑走の検出方法
Document Type and Number:
Japanese Patent JP7291092
Kind Code:
B2
Abstract:
To provide a new technology capable of detecting idling or sliding, under batch control by vector control of three or more motors.SOLUTION: Under batch control by vector control of each motor 30 in n-axes (n≥3) connected in parallel with a power feeding line, in differences between an inflow current (each-axis drive value) into a motor 30 corresponding to each of n-axes and a given reference value, a total of differences where each-axis drive value is above the reference value, or a total of differences where each-axis drive value is below the reference value is calculated, and it is detected, based on the calculated total, that idling or sliding occurs in some of n-axes.SELECTED DRAWING: Figure 1
