3. Operation
Start the power supply, select the direction of rotation with the toggle switch (TS1), and turning the
potentiometer (VR1) clockwise starts the motor to rotate. To reverse the rotation direction of the motor, turn
VR1 counterclockwise, and after confirming that the motor has stopped, reverse the TS1 switch. Operating
the TS1 while the motor is rotating may generate an unintended current, which may damage the IC.
Therefore, switch TS1 after confirming that the motor has completely stopped.
The specifications of the sample code written initially are shown below. For details, refer to the application
note of "Hall IC 120 Degree Conduction Control" on website.
ATTENTION!
Countermeasures for offensive odor, smoke, abnormal noise, heat generation, etc.
If any abnormality (such as offensive odor, abnormal noise, heat, smoke) occurs, immediately stop the power
supply and stop the motor. Please change the fuse rating according to the motor drive application.
