[QUOTE="jeallen01, post: 1128354, member: 176704"] That would be my advice to start with - and then "see what happens" in terms of whether you have any "issues" such as possible interference with the correct operation of the motor. OTOH, if none, then you are good to go; if not, then you should probably try disconnecting one or other of the shields at the motor(s) end. OTOH, I rather doubt that you will if the controller is as "good" as most people seem to claim that it is :) Edited: However, it might also be worth checking if there if is an external direct "ground" connection between the motor mount and the controller - in reality, the presence or absence of such a connection [I]should[/I] not make any difference, but if there[I] is [/I]then I would suspect the continuity of the grounding connections in the controller between the sensor circuits and the chassis ground - and also see below. In that respect, in many older "traditional" US designs there was relatively (by European/EN/IEC standards) poor general continuity between the various sections of the chassis. That meant that the overall screening efficiency of such cases was often poor ( but could often be considerably improved by cleaning the mating surfaces between those sections and tightening the securing screws/bolts). In addition, US FCC Part 15 legal requirements don't have any real requirements for protection against[I] incoming [/I]radiated and conducted interference - unlike the EN/IEC standards and EU legal susceptibility requirements! Thus, if the controller is a very old design and has not been "updated" to meet the latter then such a US design might be notably more susceptible to external interference! [/QUOTE]
