Basically Closed Loop control system is output signal gets an effect from motion of control. Error between input signal and feedback signal is gap control operation signal and need to let this signal deliver to controller to minimize gap. Then ultimately let it reach to te level requires output of system. Please see below chart to describe FASTECH Closed Loop control system.

Ezi-SERVO is an innovative closed loop stepping motor system and controller that utilizes a high resolution of motor mounted encoder to constantly monitor the motor shaft position. The encoder feedback features allows the Ezi-SERVO to update the current motor shaft position information in every 25 micro seconds and it allows the Ezi-SERVO drive to compensate for the loss of position..

Also it has encoder feedback as same as conventional servo system so recently it called as “Step Servo”.
