Typically 12-18 months before moving a product to the limited lifecycle status, Danfoss sends a letter to customers notifying them that a certain product will reach the end of its lifecycle and will no longer be produced. In that letter Danfoss will also provide information about the best alternative product for retrofit.

Ultimately, it is the customer's decision to replace the AC drive still in service.
