(1) Application in position servo: As shown in Figure 2-26, the control power supply is ±15V.
The driver stage power supply is ±22V. Connect an external H-bridge transistor switch to expand the output current. The motor
drives a potentiometer through gear transmission as actual position detection, and the feedback voltage
is introduced from pin 3. The position command voltage signal is input from pin 4. Use six resistors to divide the voltage to obtain
the peak voltage and threshold voltage of the triangular wave.
