Altivar ATV58, ATV61, ATV71
Replacing the old ATV58 drive with a new ATV61 drive. What are the main wiring changes between the two drives?
In most cases, the wiring is going to be one to one when you convert the ATV58 over to the ATV61 drives. It always helps if you have the old drawing number for the ATV58 to make sure any HOA controls are programmed correctly when switching over from the old ATV58 to the new ATV61.
