Amazing Forward Reverse Motor Control With Interlock
The ladder circuit that latches the overload condition forward or reverse must be programmed before the circuits that drive the forward and reverse starters as we will explain shortly.
Forward reverse motor control with interlock. Below is another electrical interlocking control circuit diagram. Please don t forget to like and subscribe thank you and godbless. Like subscribe and don t skip the ads.
Forward reverse motor control circuit with electrical interlock tutorial tagalog 10 duration. Most reversing controllers contain mechanical interlocks as well as electrical interlocks. Mechanical interlocking is accomplished by using the contactors to operate a mechanical lever that prevents the other contactor from closing while one is energized.
Click image to enlarge. The first coil to close moves a lever to a position that prevents the other coil from closing its contacts when it is energized. The addresses for the auxiliary contact interlocking using the r and f contacts are the output addresses of the forward and reverse starters 030 and 032.
Starter f is blocked by coil r in the same manner. Otherwise the plc program will never recognize the overload signal because the starter will be turned off in the circuit during the same scan. If an oversight allows the second coil to remain energized without closing its contacts the excess current in the coil due to the lack of the proper.
When the forward contactor coil f is ener gized and closed through the forward push but ton the mechanical interlock prevents the acci dental closing of coil r. In this video tutorial i want to share how to wire forward reverse control circuit. Mechanical interlocks are supplied by the manufacturer and are built into reversing starters.
Three phase induction motors runs with two speeds 1 direction and two speeds two directions motor control and induction motors reverse forward operation is the types of electrical interlocking. Motor control forward reverse. To prevent unintentional energization of both the forward and reverse coil at the same time the coils are equipped with normally closed contacts which are then wired in series with the opposite direction s coil to act as an electrical interlock.
