Motor identity and duty envelope
The 1FK2204-5AK11-1SB0 is a Siemens SIMOTICS S-1FK2 CT synchronous servo motor from the 1FK2 family built for SINAMICS S120 drives, with a stall torque M0 of 2.4 Nm and a rated power of 0.57 kW at 6000 rpm on a 380-480 V bus, stepping to 0.75 kW at 3000 rpm on a 200-240 V bus. Because the unit ships with an integrated holding brake, an absolute single-turn 22-bit encoder (AS22DQC), and a DRIVE-CLiQ plug plus power connector on M17 interfaces, it lands as a drop-in axis for an S120 line-up rather than a generic rotary servo.
Catalog administration and receiving footprint
On the Siemens catalog the motor carries Group Code R220 and Product Group 9021, with a quantity unit of one piece per order and a single-piece pack quantity, which fits a preferred-supplier catalog line for axis-by-axis replenishment. Receiving planning should note the 452.00 x 250.00 x 267.00 mm factory pack dimensions and the Product Class C designation, meaning the motor is built to order and cannot be returned for credit — a one-off requisition against an uncatalogued line costs more than placing the order through a controlled channel.
Compliance and export posture
RoHS compliance is in force since 01-07-06 and REACH Art. 33 disclosure obligations are met via the published Reach Information notice, while export control falls under AL:N / ECCN:N_CNDU — a clean classification that does not require special licensing for typical cross-border shipments.
