0.75 kW at 3000 rpm, brake-equipped — what the order code resolves to
The Siemens 1FK2204-5AF11-0SA0 is a SIMOTICS S-1FK2 CT servo motor sized at M0 = 2.4 Nm with PN = 0.75 kW at nN = 3000 rpm on a 380–480 V drive bus, and a derated PN = 0.375 kW at nN = 1500 rpm on 200–240 V — the lower-voltage figure is a real second duty point, not a soft minimum, and matters when the cabinet is fed from a 230 V line rather than a 400 V drive bus. It is delivered with a holding brake, an absolute single-turn 22-bit encoder (AS22DQC) read through the OCC interface, a cylindrical shaft D19 x 40 mm, an M17 rotatable plug, and an IP65 housing — the same connector family and feedback protocol that the SINAMICS S210 drive expects on its motor port.
Feedback resolution and the S210 control loop
22-bit single-turn resolution over OCC is what gives the velocity loop its low-speed smoothness on the SINAMICS S210; coarse feedback on a small-frame servo like this one is the usual reason a tuning session turns into a notch-filter exercise, so the encoder spec is load-bearing for commutation quality, not a footnote. The cylindrical D19 x 40 mm shaft and M17 rotatable plug are mechanical choices that reduce panel-side rework — the plug orientation can be set after the motor is mounted to the gearbox or coupling, which matters when the cable entry has to clear a bellows or a cable chain.
Two voltage windows, one motor
Duty is split: 0.75 kW at 3000 rpm on 380–480 V, 0.375 kW at 1500 rpm on 200–240 V. Match the BOM line to the drive bus the cabinet actually carries — spec the wrong half and the continuous torque drops by half without any fault indication.
Lifecycle and ordering identifiers
Group code R220 and product group 9021 are the identifiers to quote on the PO so the manufacturer side of the line does not cross-reference a different frame size by accident. RoHS compliance has been in force since 01-07-06; These are the three compliance hooks a procurement file expects to see cited on the shipping paperwork.
Packaging and ship-side handling
The motor ships one per pack in a 452.00 x 250.00 x 267.00 mm box — keep the original packaging if a return credit is a possibility, since the product class designation marks this as a build-to-order item that cannot be returned against credit once the seal is broken.
