1 kW at 3000 rpm with the holding brake already integrated
The 1FK2104-6AF11-0MB0 ships as a SIMOTICS S-1FK2 HD servo motor sized for SINAMICS S120 drives: standstill torque M0 of 3.2 Nm, rated power PN of 1 kW at a rated speed of 3000 rpm on a 380-480 V link (and 0.5 kW at 1500 rpm on 200-240 V), with an integrated holding brake so the axis holds position on power loss without an external brake module. Feedback is the 22-bit single-turn + 12-bit multiturn absolute encoder AM22DQC, wired through the DRIVE-CLiQ M17 plug — that combination auto-identifies the motor to the SINAMICS S120 controller and pulls the electronic nameplate into the drive parameters on first commissioning. IP65 protection on the housing plus a cylindrical shaft D19x40 mm and the power connector M17 mean the motor lives in a sealed cabinet-free machine envelope, typically a packaging line, indexing table, or feed axis where shaft sealing and connector keying decide the fit before the torque curve does.
Why the SHAFT-D19, AM22DQC, DRIVE-CLiQ combo locks you into this exact order code
Three wiring-side details decide whether this is the right build and not just the right frame: the AM22DQC absolute encoder (22-bit + 12-bit multiturn) for position retention across power cycles, the DRIVE-CLiQ M17 communication plug so the motor and S120 drive negotiate electronically, and the power connector M17 carrying the three-phase feed to the windings. Swapping encoder type or connector size on this frame is a different order code, not a field option. Build class is Siemens product class C — produced to order, not reusable or returnable for credit — which is the procurement reality behind the R220 group / 9021 product group codes: every unit is built against a specific configuration and the lead time tracks factory capacity, not shelf stock.
Sourcing a built-to-order SIMOTICS servo through independent distribution
Inbound packaging is a single piece at 452 x 250 x 267 mm, which is what your receiving dock should expect rather than a small-parcels shelf-pull.
