The VW3AE0924 is an air conditioning unit designed for Altivar 61 Plus and Altivar 71 Plus floor-standing enclosures — the versions with separate air flows or the compact variant. It's an enclosure accessory, not a drive component; its job is thermal management inside the cabinet, keeping the drive electronics within rated ambient limits.
What it fits — and what that means for a replacement search
This unit is specific to Altivar floor-standing enclosures with separate air flows or the compact version. It's not a generic cabinet cooler — the mounting pattern, airflow path, and control interface are tied to that enclosure family. If you're retrofitting a different drive brand or a standard enclosure, this won't bolt on. The Altivar 61 Plus and 71 Plus series are themselves mature/obsolete product lines, so the entire ecosystem is moving toward newer drive families (Altivar Process, Altivar Machine).
