The 3ADT218587S0222: Three analog inputs and two analog outputs are available for speed/torque reference and actual-value feedback. If your application needs more than two analog outputs, plan for an external signal conditioner or a fieldbus option module. The 73 dB(A) sound level is a shop-floor consideration — it exceeds typical office-area limits but is normal for a forced-air-cooled converter. Hearing protection zones may apply in the immediate vicinity.
Installation and compliance note
The auxiliary terminals carry an IP00 rating per IEC 60529, IEC 60947-1, and EN 60529 — no ingress protection beyond the panel enclosure. Mount the converter inside a cabinet rated for the environment; the IP00 terminals require the cabinet door to be closed and locked before energizing. Operating humidity range is 5 to 95 % RH, non-condensing.
