SINAMICS S210 family member, currently active
The Siemens 1FK2204-5AK10-1SA0 is a SIMOTICS S-1FK2 CT servo motor sized for the SINAMICS S210 drive platform, listed as currently active in production with holding brake and absolute single-turn 22-bit encoder AS22DQC. Stall torque M0 is 2.4 Nm and rated power PN is 0.57 kW at nN=6000 rpm on the 380-480 V supply, while the same frame delivers PN = 0.75 kW at nN=3000 rpm on the lower 200-240 V rail — so the voltage you feed the S210 changes the operating point on the speed-torque curve, not just the bus level.
Mechanical, brake, and connector spec
The shaft is D19 x 40 mm with feather key, degree of protection IP64, and an OCC interface connector in plug size M17 that can be rotated for cable routing during panel build. Group code is R220, product group 9021, and the listed packaging footprint is 452.00 x 250.00 x 267.00 mm — useful when checking inbound receiving on a line-down spare.
