ABSTRACT:
An apparatus and a method for discriminating position information in a position control system. The apparatus includes a position detector for detecting information regarding a current position of a motor, a position counter for counting the motor current position information from the position detector at a fixed period, a central processing unit for reading a counted value from the position counter, comparing the read value with a normal position command value stored therein, compensating for a difference value as a result of the comparison and outputting a position control value based on the compensated value, and a digital/analog converter for converting the position control value from the central processing unit into an analog signal and outputting the analog signal as a position control signal for the motor.
