7. Keep the potentiometer “REF” turned counterclockwise.
8. Connect the 24V power supply to the board on J20.
9. Press and release switch S3 once.
10. Turn the potentiometer “REF” clockwise, the motor should rotate.
11. Each press of S3 toggles the control between Run and Stop conditions.
12. To change the direction of rotation, press S2.
13. If the motor stops and LED D1 blinks, it indicates that there was an overcurrent
