Headline ratings and what they govern
The 1FK2104-6AF11-0SA0 is a SIMOTICS S-1FK2 HD servomotor in the 1FK2 family sized for the SINAMICS S210 drive platform, with a stall torque M0 of 3.2 Nm and a rated power of 1 kW at 3000 rpm on a 380-480 V bus. The lower 200-240 V window delivers 0.5 kW at 1500 rpm from the same frame, so a single order code covers a panel wired to either the 230 V class or the 400 V class supply without a frame change. M0 = 3.2 Nm sets the mechanical ceiling for sizing the gearbox and coupling on the driven shaft — accelerating the load through the required inertia ratio starts from that figure, not the continuous rating. Holding brake fitted as standard, so the shaft locks when the drive enable drops and the axis holds position without a separate brake resistor or mechanical clamp.
Encoder, shaft, and the wet end
The feedback is an absolute single-turn 22-bit encoder (AS22DQC) on a cylindrical shaft D19 x 40 mm, terminated through a rotatable M17 plug with the OCC interface — orientation on the cable entry is set after the motor is mounted, which removes the rework loop if the harness lands on the wrong side. IP65 with that shaft seal and connector face keeps the motor usable on machine surfaces exposed to coolant mist and washdown, but it does not extend to submersion — for flooded zones the datasheet envelope is the limit. Single-turn absolute means the drive knows shaft position immediately on power-up; multi-turn retention across power loss is not provided by this encoder, so any absolute homing requirement on loss of supply is handled at the controller level.
Lifecycle and compliance posture
RoHS compliance has been in force since 01-07-06 and REACH Article 33 duty-to-inform is carried through the product record, which is the documentation package expected at incoming inspection for EU-bound assemblies. Product class is the Siemens order-on-demand category — the unit is built to order, cannot be returned for credit, and is not a stockable shelf item, so the storeroom counts here are min/max against a build schedule, not free inventory.
Packaging and handling
Shipped one per pack at 452 x 250 x 267 mm, single-piece quantity unit — the carton is sized for one motor, so a multi-unit BOM ships as separate cartons on the same RFQ.
