Abstract
Disclosed are an apparatus for controlling a position of an embroidery frame, which is capable of performing an accurate embroidering operation by feed backing a position error due to mutual operations of interlocking devices for driving the embroidery frame using a displacement sensor for sensing a displacement of the embroidery frame, and a method thereof. The apparatus comprises an X-axis driver, a Y-axis driver, a sensor and a controller. The X-axis driver moves the embroidery frame along an X-axis direction. The Y-axis driver moves the embroidery frame along a Y-axis direction. The sensor senses a displacement of the embroidery frame to the X-axis and Y-axis directions, and outputs electric signals corresponding to the sensed displacement. The controller generates X-axis and Y-axis drive control signals based on the electric signal from the sensor in order to control the X-axis and Y-axis drivers, respectively.
