Hi Mick,
I have a couple of questions:
Why do you have a transformer at the input....is your incoming power supply 250V? These drives are made in Europe for European conditions
so I am bemused that you need anything like a voltage reducing input transformer....or have you Brexited already?
The next is the EMC filters between the contactor and the drives. Do you have specific advice from Schnieder that they are required or acceptable?
As I have said before, not once but a dozen times, you need line reactors NOT EMC filters, unless the EMC filter is specifically recommended by
Schneider. EMC filters tend to have capacitive input impedance and generally a poor choice for a device deriving DC voltage by direct rectification
of the incoming AC, ie a servo drive.
