3. Stepper Motor Reference Design Demonstration
The Stepper Motor Reference Design includes everything you need to set up a stepper motor demonstration.
Connect the stepper motor to the stepper motor control board following the wiring chart for the 42BYG205 motor as
shown in Table 1.
Connect the universal ac/dc power adaptor to the dc supply (P1) on the Stepper Motor Reference Design Board.
Press the Function (FUNC) button on the Stepper Motor Reference Design Board. The motor will turn in one
direction. Notice that the motor accelerates smoothly up to the maximum speed, moves at a constant speed, and
then decelerates smoothly to a standstill. Press the function button again and the motor will turn the other direction.
