Title:
DEVICE AND METHOD FOR SWITCHING LOAD SHARING CONTROL
Document Type and Number:
Japanese Patent JP2019013099
Kind Code:
A
Abstract:
To provide a method and device for switching load sharing control capable of switching to the load sharing control in appropriate timing.SOLUTION: An embodiment is provided with: a first roll load comparator which compares first load current and second load current before and after a compression command signal becomes active with each other to output an active first roll load change signal when the second load current shows predetermined change to the first load current; a first roll speed comparator which compares a first speed signal and a second speed signal before and after the compression command signal becomes active with each other to output an active first roll speed change signal when the second speed signal shows predetermined change to the first speed signal; and a control switching commander which outputs a load sharing start command signal based on the first roll load change signal and the first roll speed change signal.SELECTED DRAWING: Figure 1
