Sourcing posture: active, made-to-order
The 1FK2104-4AK00-0SA0: Group code R220, product group 9021, single-piece quantity unit. Packaging is a single piece per box at 452 x 250 x 267 mm, so the line-item lands as a configured servo, not a shelf-pulled spare.
Torque and speed envelope on the two mains
Stall torque M0 = 1.27 Nm; rated power 0.6 kW at nN = 6000 rpm when fed from a 380-480 V bus, dropping to 0.4 kW at nN = 3000 rpm on a 200-240 V supply. For machine builders running a single global machine platform, that two-rail envelope is the figure that decides whether the same motor body covers both the EU 400 V and the US 240 V cabinet variants without a re-spec. The motor belongs to the 1FK2 servo family intended for pairing with the SINAMICS S210 drive — encoder resolution, shaft and connector are pre-matched to that converter, so substitution outside the configured pair breaks the auto-commissioning handshake.
Feedback, shaft and the panel-side connector
Feedback is an absolute single-turn encoder AS22DQC at 22-bit resolution, with the OCC interface — deterministic to the cycle and ready for cyclic position loops on the SINAMICS S210 without homing on every power-up. Shaft is a cylindrical D19 x 40 mm. Cable exit is the M17 plug, rotatable — the rotation range is the small but real reason a panel builder can land the motor in four orientations without re-ordering a different connector variant. IP64 holds the body to dust and splash, so the motor belongs inside an enclosure or a sheltered machine frame, not in a washdown zone.
Compliance paper trail
RoHS compliance has been in force since 01-07-06; REACH Art. 33 information is supplied via the Reach Information clause. Material compliance for the EU market is on file, but mechanical/electrical safety agency marks (UL, CSA, CE under the LVD) are not listed in this product record and would need the partner drive's documentation to round out a control cabinet design.
