Abstract
The present invention relates to a method for setting slave identification information for an actuator movement sensing element and, more particularly, to a method for sensing a distance, by which an actuator having a lens assembly coupled thereto has moved in one direction among an x-axis, a y-axis, and a z-axis, and transmitting the sensed distance to a master controller according to a two-wire interface scheme. The method comprises the steps of: when a slave identification information change command is received from a master controller, checking whether actuator movement distance sensing data is input from a hall sensor allocated to itself; and as a result of the checking, when actuator movement distance sensing data equal to or greater than a set value is input, setting slave identification information assigned at the time of production to be changed into slave identification information transmitted by the master controller.
