What the 2.4 Nm / 0.75 kW envelope buys you
The 1FK2204-5AK00-2MA0 is a SIMOTICS S-1FK2 CT servo motor sized for the SINAMICS S210 drive family, with a stall torque M0 of 2.4 Nm and a rated power PN of 0.57 kW at nN=6000 rpm on the 380-480 V rail and 0.75 kW at nN=3000 rpm on the 200-240 V rail. That dual-rail power curve is the practical takeaway: on 230 V-class supplies the motor delivers 0.75 kW at half the field-weakening ceiling (3000 rpm), and on 400 V-class supplies it trades torque for speed up to 6000 rpm — so the drive voltage rating, not just the torque, sets where the motor sits in its working envelope.
Feedback resolution and the loop it enables
Feedback is the AM22DQC absolute encoder at 22-bit single-turn plus 12-bit multiturn resolution, sent over the OCC interface — single-turn resolution of roughly 4.8 million increments lets the S210 close a position loop tight enough for short-stroke indexing and registration without mechanical slack dominating the error budget. For tuning, the encoder's resolution matters more than its bit count: at 6000 rpm the 22-bit feedback updates faster than 1 arc-minute per sample, so velocity-loop noise stays below the current-loop bandwidth and a notch filter in the 200-300 Hz band will actually bite a mechanical resonance instead of aliasing around it.
Mechanical fit, sealing, and the cabinet reality
The shaft is a plain cylindrical D14 x 30 mm stub and the power/feedback connector is a rotatable M17 plug, so cable routing can be set after the motor is bolted down — useful when the cabinet layout forces a 90° turn the drawings did not anticipate. Ingress protection is IP64 at the body, which is dust-tight and resistant to splash from any direction — adequate for a panel-internal machine zone but not a washdown or outdoor enclosure; if the cell sees cutting fluid or food-grade cleaning, plan on a secondary shroud or step up to a higher-IP sibling.
Lifecycle, compliance, and the BOM-side reading
Lifecycle status is Active, and the product class is C — built to order, non-returnable — so the BOM commitment matters: the motor is produced against the order, not pulled from shelf inventory, and lead time is the manufacturing window rather than a stocking position. Compliance posture is RoHS-compliant since 01-07-2006, with REACH Art. 33 disclosure carried via the standard Reach Information channel, and export classification AL:N / ECCN:N_CNDU — the part does not trigger an export licence and ships against a standard commercial invoice.
Sourcing posture for an active built-to-order servo
Because the motor is class-C made-to-order, the procurement question is not 'do you have one on the shelf' but 'can you confirm the build window at the required quantity' — that confirmation, together with current pricing, is what an RFQ returns, and that is the channel through which the 1FK2204-5AK00-2MA0 is sourced.
