Title:
SERVO MOTOR CONTROL DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2007/126024
Kind Code:
A1
Abstract:
Provided is a servo motor control device capable of improving current control loop response and preventing vibration of a servo motor. The servo motor control device includes: current detection means for detecting an output current value of the servo motor fed back by a current control loop; and current loop-gain switching means for increasing the gain of the current control loop when the detected output current value is smaller than a preset threshold value and reducing the gain of the current control loop when the detected output current value is greater than the preset threshold value.
