Siemens 6SE6440-2UD17-5AA1 is a Micromaster MM440 variable-frequency drive (VFD) rated for 0.75 kW output to control a three‑phase motor from a 380–480 V supply (nominal 400 V) with a 47–63 Hz input range. The UD17-5AA1 variant is specified as without an internal Class A filter, and Profibus DP connectivity is achievable with the external 6SE6400-1PB00-0AA0 communication board for PROFIBUS networks. As part of the Micromaster 440 family, it provides industrial-speed control for three‑phase motors in automation applications.
