PLC | mask cable connection? One side, both sides of the ground PART-2

[http://vkinngworld.blogspot.com/]


In the previous article, one might think,
Is to one side seems to be grounded!!


In actual fact, you should look at both sides of the equipment is grounded and fixed!!


If the wiring between the motor with the controller,mask cable(ground line) will  take 1  sides ,
Because the motor has a ground with the controller.


But if it is between the controller with external sensor,
mask cable(ground line) will  take 2 sides,
Because the sensor is not grounded, a ground controller.


So mask cable, isolation
To take a side or2 side ground, depending on the situation,
Not every case is appropriate.
