Ratings that matter for HVAC duty
The 3AXD50000956845: Ambient temperature tops out at 60 °C, which covers most mechanical rooms even near boiler or chiller plant. The IP20 enclosure keeps dust and tools out but expects a clean panel environment — not for washdown or outdoor mounting. BACnet communication is built in, so the drive talks directly to a building management system without an external gateway.
Frame R4 mounts as a module on a backplate or DIN-rail adapter (not included). The drive is rated for installation up to 2000 m altitude without derating; above that, consult the manual for current reduction. Standby loss is 37 W — factor that into panel cooling if the drive idles between call cycles. Sound level is 69 dB(A), noticeable in a quiet mechanical room but typical for a fan-cooled drive of this power class.
