How to check NRED,APOW, AINT cards in Acs800 drive with external supply, not placeing in drive.
Please guide me.
each of the cards you mentioned are connected to the drive with specific signals that are an integral part of it.
To be able to control these cards outside the drive, it is not enough just to power them: you need to know which accessory signals they require, and which signals they supply to the other parts that make up the drive itself.
Moreover, not having the necessary SW I do not see how you could do controls that are not only visual.
The equipments and last but not least, the diagrams that are necessary for a correct connection are exclusively for access to ABB laboratories.
I suggest you contact your nearest ABB service with confidence, who can assess whether the cards you have are repairable or not.
