Double-axis feed into the SINAMICS S220 line
The 6SL5120-2UE21-0AD0 is a Siemens SINAMICS S220 Double Motor Module in booksize format, taking a 495-720 V DC common-bus feed and driving two independent 3AC outputs at 0-480 V, each rated 2x11.2 A input and 2x9 A output for 2x4 kW of shaft power on a shared chassis (cites:). Built as a booksize D-type with internal air cooling only and IP20 protection, the module slots into a multi-axis S220 line-up where the rectifier, braking, and control units sit on either side and the double module just injects two motor inverters into the same bus (cites:).
Firmware gating and what that means for spares
Support is locked to firmware V5.2 SP3 HF10 and later — a spare module pulled from older stock still has to be commissioned against a controller running that release or higher, otherwise the drive handshake fails and the axis never enables (cites:).
Substance notes — lead, packaging, export
REACH Art. 33 disclosure flags lead (CAS-No. 7439-92-1) above 0.1 % w/w, and RoHS compliance is declared since 04-09-17 — both are the standard Siemens dossier entries for the booksize generation, no derogation paperwork beyond the Art. 33 note (cites:,). Export classification is AL:N / ECCN:3A999A and the unit ships one per carton at 365.00 x 565.00 x 60.00 mm, which lines up with the booksize D-type footprint inside a typical S220 cabinet (cites:,).
