Title:
SYNCHRONOUS CONTROL DEVICE FREE IN GEAR RATIO OF SPEED CHANGER
Document Type and Number:
Japanese Patent JP2019165527
Kind Code:
A
Abstract:
To realize synchronous control in a case of free in the gear ratio (a value including an optional numerical value not larger than a decimal point) of a speed changer, although the synchronous control of multiple motors has been in practical use in the past when the gear ratio of the motor and a machine shaft of the speed changer is 1/N, K/M (N, K and M are positive integers).SOLUTION: A synchronous control device of the present invention detects variation of a command position by a rotation command signal, and detects the variation of a feedback position from a feedback signal of rotation. The synchronous control device free in the gear ratio of a speed changer can be realized by detecting an incremental positional deviation from the two positional variations and by applying it to motor controlling.SELECTED DRAWING: Figure 1
