Defining the motor and its drive-system fit
1FK2204-5AF00-0MB0 is a SIMOTICS S-1FK2 CT servomotor in the 1FK2 product family, designed to pair with SINAMICS S120 drives over the DRIVE-CLiQ plug M17. The CT (Compact Torque) family targets high-dynamics motion axes where the encoder resolution and shaft stiffness matter more than the continuous-torque ceiling. Continuous torque M0 sits at 2.4 Nm with a rated power PN of 0.75 kW at nN=3000 rpm on the 380-480 V supply rail, and PN=0.375 kW at nN=1500 rpm on the 200-240 V rail. The 2:1 power drop between the 400 V and 230 V rails is the standard SINAMICS S120 derating at the lower line voltage, not a motor-side limit.
Encoder, shaft, and mechanical envelope
Position feedback is the absolute encoder AM22DQC — 22-bit single-turn plus 12-bit multi-turn — which returns absolute position on power-up without a homing cycle. For multi-axis machines that lose line voltage mid-cycle, the multi-turn range covers the full machine travel without an external battery module. The shaft is a plain cylindrical D19x40 mm stub without a keyway or feather, and the housing carries IP64 protection. IP64 keeps the motor sealed against splash and dust ingress — adequate for cabinet-internal or sheltered cabinet-external mounting, but not for washdown or food-grade duty where IP65 or higher is the gate.
Production status and order classification
Siemens lists 1FK2204-5AF00-0MB0 as active. The Group Code R220 and Product Group 9021 are Siemens-internal classification fields used for pricing and ordering rather than engineering fit. The order code sits in Product Class C: items manufactured or produced to order, which cannot be reused or returned against credit. For BOM planning that means standard cancellation and return rights do not apply — confirm quantity, winding variant, and encoder assignment before issuing the purchase order.
Compliance, packaging, and trade-control posture
RoHS compliance has been in force since 01-07-06, and REACH Article 33 duty-to-inform is met via the published Reach Information set. Export control is open: AL=N and ECCN=N_CNDU — no licence trigger for the standard commercial destination. Shipping carton is 452.00 x 250.00 x 267.00 mm at one piece per pack. Servo motors of this frame are dense and sensitive to shock — the packaging dimensions matter more for the receiver's receiving dock and crate-stacking plan than for the spec sheet.
