Operating Principle
Here is the truth table of Motor B:
This truth table shows the different states of Motor B based on the values of input pins B-1A and B-1B. It indicates the
direction of rotation (clockwise or counterclockwise), braking, or stopping of Motor B.
B-1A B-1B The state of Motor B
1 0 Rotate clockwise
0 1 Rotate counterclockwise
0 0 Brake
1 1 Stop
Here is the truth table of Motor A:
This truth table shows the different states of Motor A based on the values of input pins A-1A and A-1B. It indicates the
direction of rotation (clockwise or counterclockwise), braking, or stopping of Motor A.
A-1A A-1B The state of Motor B
1 0 Rotate clockwise
0 1 Rotate counterclockwise
0 0 Brake
1 1 Stop
