Abstract
PURPOSE: To perform the decision of the optimum speed reduction point in the short period and thus increase the positioning accuracy, by calculating and varying the speed reduction point of the motor in accordance with the initially set error.
CONSTITUTION: Motor 10 is connected to machine 12, and the speed is controlled by constant voltage type speed controller 11. The comparison is given through comparator 14 between set target value R of the working and position P of the machine. And the error E is applied to speed command unit 18, speed reduction point study unit 16 and speed reduction point calculating unit 17 each. Thus speed reduction point PD is calculated by calculator 17 and via error E, start signal S0 and study value L given from unit 16 each to be then supplied to unit 18. At the same time, unit 18 gives the comparison between point PD and error E and then transmits speed command VS to controller 11. When setting end signal P0 is generated from comparator 14, the study is performed for each constant by error E and via unit 16. In this way, the optimum speed reduction point is decided in the short period, thus increasing the positioning accuracy.
