When the forward rotation operation switch PB1 is closed, the forward rotation relay coil R1 is energized and activated via the stop operation switch PB3 and the normally closed contact R23 of the reverse rotation relay R2. When the relay R1 is activated, the normally open contact R13 is closed, the brake coil B is energized and the brake is released, the contact R12 is closed, and the motor M is operated in the forward direction. Further, by closing the contact R11, a self-holding circuit is constructed, and even if the forward rotation operation switch PB1 is opened, the relay R1 continues to be energized and the motor continues to rotate in the forward direction. Furthermore, since the normally closed contact of contact 13 is opened, even if the reverse operation switch PB2 is closed, the relay coil R2 is not energized, and the forward and reverse rotation relays R1 and R2 are not energized.
This prevents both from being energized at the same time. Next, when the stop operation switch PB3 is opened, the power to the relay coil R1 is cut off, and the motor M suddenly stops.
The reverse operation is also the same.
