As the control part of the correction system, the control board can make the actuator perform corresponding actions based on different control signals.

In the automatic correction process, the control board receives the offset signal transmitted by the edge sensor and obtains the pulse frequency corresponding to the required speed of the control motor through specific calculations. This pulse is output to the servo controller to drive the motor and achieve the correction action. The larger the offset, the higher the speed of the motor and the greater the force of correction.
