Forward run and reverse run are controlled with the ON/OFF
of the direction sign (SIGN).
•
The motor will forward run when the direction sign is HIGH.
•
The motor will reverse run when the direction sign is LOW.
Forward run and reverse run are controlled with the ON/OFF
of the direction sign (SIGN).
The motor will forward run when the direction sign is LOW.
The motor will reverse run when the direction sign is HIGH.
