As soon as reverse contactor. The figure given below shows the control and power diagram of forward and reverse starter diagram.
Dc Motor Forward Reverse Circuit Controlled By The Double
Forward reverse motor control. As the name defines forward reverse starter is used to run the motor in both sides forward and reverse. In the above reverse forward motor control circuit diagram. The forward reverse motor control is used in a system where forward and backward or upward and downward movement in the operation are needed. In the diagram i shown also a light indicator which will be. In the diagram i connect the incoming three phase supply l1 l2 l3 to the mccb circuit breaker molded case circuit breaker. The forward and reverse pushbuttons provides a means of starting the motor in either forward or reverse so that the limit switches can take over automatic control.
Plc example for motor. Forward green switch is use for to run motor forward and reverse switch is used for run motor on reverse mode. The red push button is for switch off the motor. An example of which are shown in figures below a and b. These two normally open push button switch shown with green color. Forward and reverse operation of motor can be obtained by interchanging any two of its three terminals.
For three phase motor forward reverse control circuit. For the common reversing ac motor run your neutral wire directly to your motor the hot lead through the 1 2 terminals and your reversing leads through the 4 3 6 5 terminals. The forward and reverse motor commands will operate normally if no overload condition exists because the overload contacts will provide continuity. The reverse contactor coil energized and three phase induction motor runs in the reverse direction. The workpiece starts moving on the left side and moves to the right when the start button is pressed. Reverse direction press on push button r on.
The forward reverse motor control is used i a system where forward and backward or upward and downward movement in the operation are needed. An example of which are shown in figures below a and b. Your ac motor must be designed for reversing not all ac motors can be reversed without additional provisions. These forward and reverse starters are dol type and not used above the 05 hp motors. The forward reverse motor control is used i a system where forward and backward or upward and downward movement in the operation are needed. When it reaches the rightmost limit the drive motor reverses and brings the workpiece back to the leftmost position again and the process repeats.
We use 2 magnetic contactors as forward reverse switch. However if an overload occurs the contacts in the plc program will open and the motor circuit will turn off. The reverse contactor coil gets supply through phase r off push button f2 reverse contactor coil r on push. Here i showed the forward reverse wiring diagram.
