Happy new year everyone.
This is more of a Electrical engineering question than a PLC one.
Can a Motor and a VFD that is rated for 240/480 60/50Hz operation be used on a system that has utility supply power of 3-Phase 400VAC? Customer is dictating 400VAC transformers for both their US and overseas factories? However, control cabinet electronics being used for powering the PLC, 24VDC Power Supplies etc., are running off from a 120 V step down from this very same 400 VAC transformer.
Can this be done or do I need to look for a VFD and a motor that is rated strictly for 400VAC use?
Thanks.
