What the 1FK2104-4AK10-0MA0 actually delivers on the bench
The 1FK2104-4AK10-0MA0 is a SIMOTICS S-1FK2 HD servo motor sized for a 0.6 kW shaft load at a 6000 rpm rated speed on a 380-480 V SINAMICS S210 drive, with a second duty point at 0.4 kW at 3000 rpm for 200-240 V operation, so the same motor covers a wide mains envelope without re-sizing the cabinet. Static torque M0 is 1.27 Nm, the holding brake is built in, and feedback is the absolute encoder AM22DQC at 22-bit single-turn plus 12-bit multiturn, which means position is retained through power-down and the drive does not need a homing run after every restart. The motor ships in an IP64 housing with a cylindrical D19x40mm shaft, an OCC interface, and a rotatable M17 plug — the plug orientation can be set to the cabinet routing on-site without unbolting the connector body, which is the small detail that saves an afternoon in a retrofit. Production status is active on Siemens's records, which puts it firmly inside the current 1FK2 generation for SINAMICS S210 — this is not a legacy 1FK7 motor dropped onto a modern drive, it is the native match.
Family placement and paperwork identifiers
The product is classed as Product class C, which means it is produced to order and is not returnable against credit; the BOM line should be sized once and quoted straight rather than run as a stocking part.
How it integrates with a SINAMICS S210 line
The OCC interface and M17 plug lock the motor to the SINAMICS S210 cable family — the drive-end cable is the matching OCC connector, and because the plug on the motor body is rotatable the cable exit direction can be set once the motor is bolted to the gearbox or reduction flange. For shop-floor duty, IP64 with the built-in holding brake means the motor takes a position-hold role directly on a vertical axis without a separate external brake resistor — the brake engages on the drive's enable-disable edge and the encoder AM22DQC tells the controller where the axis stopped without a reference move. Packaging is a single piece at 452.00 x 250.00 x 267.00 mm, which is the box footprint the receiving dock needs to plan for on a small-shop bench — not a pallet, but not a shelf-bin either.
