Replacement Guides: official migration paths
for discontinued drives and HMIs

When a manufacturer discontinues a VFD or HMI series, they usually publish an official successor and a model cross-reference — but "successor" is not the same as "drop-in replacement." Each guide below summarizes the manufacturer's own migration path, the model mapping, and what to verify before you order.

How to use these guides

Every guide here is built the same way: the manufacturer's official successor platform, an official model cross-reference table, the option/fieldbus changes that come with it, and the specific checks worth confirming before you commit — current rating, dimensions, communication, encoder feedback and more. None of these treat "successor" as an automatic one-to-one replacement — where the manufacturer doesn't guarantee interchangeability, we say so.
