The 3ADT218520S0222: Rated for 50 Hz line frequency. Three analog inputs and two analog outputs are onboard for speed reference and feedback loops — enough for a single-motor drive with tacho or encoder feedback. The 60 dB(A) sound level is typical for a forced-air-cooled converter at this power; plan for a panel that keeps operator stations clear of the noise.
Auxiliary terminals are rated IP00 per IEC 60529 and IEC 60947-1 — open-frame, so the converter lives inside a cabinet with a higher enclosure rating. Operating humidity range is 5 to 95% RH, non-condensing. Plan for top and bottom cable entry clearance per the frame H3 drilling plan.
