In the picture with a servo motor driver circuit over the MC33030 IC has 2 pieces of position control and feedback control. F POT serves to regulate or control the system feedback or closed loop feedback system servo motor driver. While the R POT is used to adjust the position of a servo motor movement.

Working voltage servo motor driver circuit using MC33030 IC is 12 volts working voltage in accordance with a servo motor is used. The maximum current that can be controlled using a servo motor driver circuit MC33030 IC is 1 ampere maximum. Therefore, it should not be used to control a servo motor with a current consumption of more than 1A, because it can damage the MC33030 IC is used in the servo motor driver circuit.
