When F/R is “L”, the Hall input while the motor is rotating must be input in order from 1 to 6 of the above table.
When the Hall input is performed by the reverse order, it will not become the soft current-carrying output.
(The motor is driven by the 120 degrees current-carrying only.)
Also, when F/R is “H”, the Hall input while the motor is rotating must be input in order from 6 to 1 of the above table.
When the Hall input is performed by the reverse order, it will not become the soft current-carrying output.
(The motor is driven by the 120 degrees current-carrying only.)
