2.4 Nm stall, 1.07 kW on the S210 bus
The Siemens 1FK2104-5AK10-1SA0 is a SIMOTICS S-1FK2 HD servo motor built into the 1FK2 family that pairs with the SINAMICS S210 drive platform. It carries a stall torque M0 of 2.4 Nm and a rated power PN of 1.07 kW at nN = 6000 rpm on a 380–480 V bus, with an alternate rating of PN = 0.75 kW at nN = 3000 rpm on a 200–240 V bus. That dual-bus rating matters for panel builders sizing a SINAMICS S210 line that sees both 230 V and 400 V infeed variants on different machines.
Where it fits on the line
A 1FK2 frame at 2.4 Nm is the right-sized spec for short-cycle positioning axes — indexing tables, small-format pick-and-place, and packaging-conveyor servo stations — where the holding brake holds the axis during power loss and the 6000 rpm ceiling covers the cycle speed. The M17 rotatable plug matters in tight cabinet layouts where the cable has to come off the motor at an angle the standard 0° exit will not allow. Mounting is the standard SIMOTICS S-1FK2 flange footprint with a feather-keyed shaft, so coupling alignment follows the usual Siemens servo procedure — no adapter plate needed when replacing a same-frame 1FK2 in an existing machine. The IP64 rating covers dust ingress and splashing water, which is enough for typical cabinet-fed industrial cells but not for direct washdown zones; if the motor sits in a food-grade line with high-pressure cleaning, the IP64 ceiling is the limit.
Lifecycle and compliance paperwork
Lifecycle stage is current and the product is classed as Active. Product class C means the unit is produced to order and cannot be reused or returned against credit — a standard condition on built-to-order servo motors where the windings, encoder, and brake are configured at build. Packaging quantity is one piece per shipper at 452.00 x 250.00 x 267.00 mm outer dimensions. Export control is AL:N / ECCN:N_CNDU, which means no special export license is triggered for typical commercial destinations. The procurement-side identifiers — group code R220 and product group 9021 — are what shows up on the Siemens PO line for this family.
