Position controlling apparatus for embroidery frame in an embroidery machine, comprises X-axis driver, Y-axis driver, outputting electrical signal sensor, and controller to generate X-axis and Y-axis drive control signals
A position controlling apparatus comprises X-axis driver; Y-axis driver; a sensor to sense a displacement of the embroidery frame to the X-axis and Y-axis directions, and outputting electric signals; and a controller to generate X-axis and Y-axis drive control signals based on the electric signals from the sensor to control the X-axis and Y-axis drivers, respectively. A position controlling apparatus comprises an X-axis driver to move the embroidery frame (400) along an X-axis direction; a Y-axis driver to move the embroidery frame along a Y-axis direction; a sensor (500, 600) to sense a displacement of the embroidery frame to the X-axis and Y-axis directions, and outputting electric signals corresponding to the sensed displacement of the embroidery frame; and a controller to generate X-axis and Y-axis drive control signals based on the electric signals from the sensor in order to control the X-axis and Y-axis drivers, respectively. An independent claim is also included for a method to control a position of an embroidery frame comprising detecting an electric signal corresponding to a displacement after moving the embroidery frame along an X-axis and a Y-axis; and generating the X-axis and Y-axis drive control signals based on the electric signal detected.
