Message: Resolver Feedback Cable for ABB Servo Motor and Drive System.
We have been using this Baldor (now ABB) servo motor and drive system for years with no problems.
Then about a year or so ago we stated having problems.
I have attached some data that I gathered up.
We believe the problem is with the resolver feedback cables.
We can us an older cable with a new system and it work fine, but when we put a cable that has been manufactured from 2021 or later the systems are very unreliable.
We understand that these resolver feedback cables are of a higher specification than other cables due to the noise/interference protection that these cables have.
So that bring us to why we are wanting to get a resolver feedback cable produced by someone else besides ABB to see if this problem can be resolved.
I have attached a excel sheet with cable date and information along with so testing that I have been doing.
