Active production, factory-traceable supply
Siemens lists 6SL5310-1BE11-0DF1 as a current-production SINAMICS S210 servo converter, sourced against the BOM through the franchised channel so the unit ships traceable to the manufacturing lot and carries full manufacturer warranty. The return class is B — return restricted, channel partner handles any RMA, which is normal for the S210 line and not a defect flag.
Ratings envelope and what drives the fit
The S210 platform takes 200-480 V three-phase at 3.8 A input with a -10/+10% tolerance window and 45-66 Hz line frequency, so the same converter rides 208 V, 400 V, 480 V and 50/60 Hz factory supplies without re-tapping. Output is 0 V to 550 Hz at 3.0 A into a 1.0 kW synchronous servo — the 550 Hz ceiling is the headroom for high-speed spindle and indexing axes rather than a steady-state operating point. Frame size A lands at 50 mm wide by 270 mm tall by 220 mm deep in IP20, which is the cabinet-mount form factor — this drive sits behind the panel door, not on the machine frame, so drip, dust and washdown ratings are not part of the spec and the enclosure must carry the IP rating for the installation environment. The single-piece shipping pack measures 350 x 400 x 60 mm.
