Abstract
A calibration method for servo is provided, wherein a motor of the servo is activated at a low-speed mode to drive a moved member of the servo moving to a first limit position and a second limit positions. During the movement of the moved member, a motor control power of the motor is monitored continuously to determine whether the motor control power exceeds a threshold value. When the moved member reaches the first or the second limit position, the motor control power is raised to exceed the threshold value and a motor coordinate value corresponding to the first or second limit position is determined simultaneously. Finally, a conservation relation for determining the actual coordinate by the motor value can be derived according to the values of actual coordinate of the first and second limit positions, and the values of the corresponding motor coordinate.
