Hi guy's, interesting topic of grounding. If you were to run a control cable, that uses screened leads, from a plc to a drive would you ground at both ends? I know it is industry practice, if the cable, ie instrumentation cable, contains a bare wire "what i like to call a drain wire" even if it's inside a foil screen, should be grounded only at one side. ie. ground at transmitter leave floating back at panel.
If grounded at both ends it could cause a ground loop which will cause you headaches. I just read a manuel that recomended grounding the screen at both ends of the cable. What do you think of this?
