Hi, EMC issues require a holistic approach!! Don't simply concentrate on the Analogue wiring because that's where you can see the problems. I have encountered installations in the past where Analogue EMC/RFI is reported and even though the AQ/AI wiring was as per the manual, the power output wiring to the motor was wired in single cores all through the panel to the field connections at the bottom. Clearly, this radiated noise was then being induced in all the adjacent wiring, even causing problems in the analogue wiring of the next drive that wasn't even running. Have a look at the EMC Installation Guidelines Regards, Graeme |
