Program example: Switching the direction of rotation with H-bridge
Switching the direction of rotation with H-bridge
Option 1: Switching the direction of rotation - directly
Only use for really small motors!
Function description: The motor can be started with button S1 in clockwise rotation (i.e. K1 active) and with button S2 (i.e. K2 active) in counterclockwise rotation. Precondition: The OFF button S0 is not pressed.
The direction of rotation can be switched directly from clockwise to counterclockwise rotation and from counterclockwise to clockwise rotation.
The process state diagramm for direct switching:
Direct reversal of direction of rotation
Option 2: Switching the direction of rotation - indirectly
The motor can be started with pushbutton S1 in clockwise rotation (i.e. K1 active) and with pushbutton S2 (i.e. K2 active) in counterclockwise rotation. Precondition: The OFF pushbutton S0 is not actuated.
The direction of rotation can only be changed after the stop button S0 has been pressed. The process diagram is as follows:
Indirect reversal of direction of rotation
