Mosfet based DC Motor Speed Controller. These two normally open push button switch shown with green color. Figure 5 – Forward/reverse motor wiring diagram. The reverse contactor coil energized and three phase induction motor runs in the reverse direction. In the event of an overload, both motor starter output coils will be dropped from the circuit because the PLC’s … Note that the motor circuit also uses the overload input, which will shut down the motor. Keep up with the great work. Circuit diagram. i am very grateful for all the effort. A fictional bit will automatically cause a restart. In this wiring diagram, both the forward and reverse coils have their returns connected to L2 and not to the overload contacts. Forward green switch is use for to run motor forward and reverse switch is used for run motor on reverse mode. Thank you very much for this article. Describe and demonstrate how transformers are used in motor control circuits 6. The forward and reverse motor commands will operate normally if no overload condition exists because the overload contacts will provide continuity. There was no PLC at the time I learned this schematic (1993) during my vocational school class. The overload contacts are connected to L1 on one side and to the PLC’s input module on the other (input 003). As we have already shared the Starting method of Three Phase Motor by Star Delta Starter with Timer Circuit (Power and Control Circuits). kindly reply on rashid.akbar@ial.com.pk.
