Abstract
A method of operating a motor controlled by a closed loop servo control system is provided. The closed loop servo control system employs a digital filter, such as a PID filter, that employs one or more gain coefficients. The method includes temporarily increasing one or more of the gain coefficients by a corresponding first predetermined amount when the motor reaches a coefficient boost motor position that is a predetermined distance before a commanded motor rest position, and decreasing the one or more of the gain coefficients by a corresponding second predetermined amount a predetermined time after the motor reaches the commanded motor rest position.
