Question

Design a control for four electric motors. Motors 1, 2, and 3 are to be controlled separately. When any one of the three starts, motor 4 is to start. Motor 4 can also be started independently of the others. If any motor reaches an overload condition, it will shut down all of the motors. In addition, there is to be a master start-stop switch (momentary) to make it possible to manually shut down all operating motors at once. The master start switch energizes the control circuit after which any particular motors is started individually. Report your circuit in ladder diagram form.

Answer 1

answer:

1. # inside the primary row ,
2. the master create key start the recollection small piece which power the entire route.
3. It is latch to stay behind thrilled constant following departure the button.
4. bring to a close is second-hand to deenergize the entire arrangement so so as to every speed twist off. I0.6 to I 1.2 are the overwork sensors for every speed which also de-energize the course in holder of surplus.
5. #In the line up 2 recollection bit energize the route. what time we bear down on participation I0.1 the coast q0.0 starts.It is also latched so with the intention of it can be continue consecutively .
6. # likewise in row 3 I0.2 start motor 2 which is q0.1. # In row 4 I0.3 starts motor3. # In row 5 outputs of all motors are taken as contribution to speed 4 so so as to at what time any single of the 3 coast starts it invigorate the route and cruise 4 starts (q0.3).
7. It be able to also be ongoing by by means of an contribution I0.4.
8. # STOP switch IS agreed IN ROW 1 TO end the motors .
9. Also whenan excess occurs in any of the motors , the surplus antenna de-energize the reminiscence bit which control off all of the motors at previously.
