Three-Phase Logic Truth Table (IN = "H" refers to the state where IN
When the OFF mode is selected during reversing at the REVSEL pin, it is necessary to specify the Hall input condition.
With F/R = "L", the condition in which the Hall input is entered in the order from 1 to 6 in the above table is considered the forward rotation and that in the
reverse order is considered reversing.
With F/R = "H", the condition in which the Hall input is entered in the order from 6 to 1 in the above table is considered the forward rotation and that in the
reverse order is considered reversing.
S/S Pin
BR Pin
When S/S and PWMIN pins are not used, set the input to the L level voltage.
When REVSEL and BR pins are not used, set the input to the H level voltage or the open condition.
