Headline torque and speed envelope
The 1FK2104-4AK10-2SA0 ships from the 1FK2 HD line with a stall torque M0 of 1.27 Nm and a rated output of 0.6 kW at nN=6000 rpm on a 380-480 V supply — dropping to 0.4 kW at nN=3000 rpm on the 200-240 V supply rail — so the same motor slots into both the European 400 V class and the North American 230 V class drive cabinets. Because the unit carries an integrated holding brake, a 22-bit single-turn absolute encoder (AS22DQC) and the OCC interface, it mates one-to-one with a SINAMICS S210 drive on the 1FK2 servomotor family and dispenses with an external braking resistor or separate resolver cabling.
Mechanical fit and shaft interface
Mounting hardware is a cylindrical shaft D14 x 30 mm with IP64 sealing on the body — adequate for cabinet interiors and light splash zones, not for washdown or outdoor exposure. The M17 connector on the motor is rotatable, which gives the wireman a practical range of cable exit angles during cabinet layout without forcing a re-rotation of the motor flange.
Procurement identifiers and order mechanics
Siemens files this motor under Group Code R220, Product Group 9021, with a single-piece quantity unit and one-piece pack quantity — both relevant when the BOM line is built up one axis at a time. Product class is recorded as built-to-order / non-returnable: each unit is produced to order, so the tail-spend buyer should plan a single line on the preferred-supplier catalog and avoid splitting the PO across brokers.
Compliance posture and shipment gating
Export control markings read AL:N / ECCN:N_CNDU, so the order does not trigger a dual-use licence check at the freight forwarder for typical industrial destinations.
