Form factor and what arrives in the crate
The Siemens 1FK2204-5AF01-1MB0 ships as a single-piece SIMOTICS S-1FK2 CT servo motor sized for SINAMICS S120 drives, with M0 = 2.4 Nm, PN = 0.75 kW at nN = 3000 rpm on a 380-480 V supply and PN = 0.375 kW at nN = 1500 rpm on a 200-240 V supply. The motor carries an IP65 housing, a D19 x 40 mm shaft with feather key, an absolute encoder AM22DQC (22-bit singleturn + 12-bit multiturn), a DRIVE-CLiQ plug M17 for the feedback cable, and a power connector size M17. Packaging dimensions for a single unit are 452.00 x 250.00 x 267.00 mm — a compact footprint that drops into a typical cabinet-feed-through mounting plate without rework.
Ratings translated to fit
The dual rating window (0.75 kW at 380-480 V and 0.375 kW at 200-240 V) is the headline constraint: the same winding supports a 400 V-class line at full rated power and a 230 V-class line at half power — confirm which supply the panel will feed before commissioning. IP65 limits the installation envelope to dust-tight, jet-water-resistant duty; this is a cabinet- or machine-body mount, not an open washdown zone where IP67 or higher is required. DRIVE-CLiQ carries both the encoder words and motor identification into the SINAMICS S120 — when the motor is replaced, electronics data is auto-loaded, and parameter mismatches surface as F-type faults during the first ramp-up rather than at runtime.
Compliance and documentation on the unit
The part has been RoHS-compliant since 01-07-06, carries REACH Article 33 candidate-list disclosure obligations, and ships under export control AL:N / ECCN:N_CNDU — straightforward cross-border movement outside dual-use controls. The product class is C — built to order with no return-for-credit and no reuse path, so stock-out on a critical axis means a new build slot, not a pulled-and-reboxed spare.
Lifecycle and procurement posture
Siemens lists the 1FK2204-5AF01-1MB0 as Active in the 1FK2 servomotor family; production runs to order with no last-time-buy notice on the family record.
