Via the digital control inputs A and B the direction/mode of operation is determined.
The following states are possible:
Level A Level B Mode of operation
0 0 Output stage disabled (no current).
0 1 Counter-clockwise rotation
(according to the arrow indicating the direction of rotation on the pump lid):
Main / operating direction of rotation of the G-BH100!
1 0 Clockwise rotation
(opposed to the arrow indicating the direction of rotation on the pump lid):
1 1 Breaking
Please take also note of the following data:
