Title:
MOTOR DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/167808
Kind Code:
A1
Abstract:
A motor drive device according to the present invention drives a motor while carrying out feedback control so that an actual operation follows a command. The motor drive device comprises: a feedback control unit for carrying out feedback control by outputting a torque command; and a viscous friction calculation unit for calculating a viscous friction torque compensation value by multiplying a speed command by a viscous friction coefficient. The motor drive device drives a motor on the basis of a drive signal created by adding the viscous friction torque compensation value to the torque command. The motor drive device is provided with an evaluation index measurement unit for measuring an overshoot amount and positioning stabilization time by inputting a position command and a motor position or a load position, and a servo adjustment unit for carrying out positioning operations a plurality of times by changing a viscous friction coefficient and determining a viscous friction coefficient so that the overshoot amount is a designated value or the positioning stabilization time is the minimum value.
