Servo sizing for an S210 axis
The Siemens 1FK2104-6AF00-2SA0 is a SIMOTICS S-1FK2 HD servo motor built for the SINAMICS S210 drive platform — the 1FK2 family is the native motor line for that drive, so the electrical interface, OCC connector convention, and encoder protocol are matched by design rather than adapted. Continuous stall torque M0 is 3.2 Nm with a rated power PN of 1 kW at nN 3000 rpm on the 380-480 V winding, and PN 0.5 kW at nN 1500 rpm on the 200-240 V winding — the motor is wound so one frame covers both European 400 V and North American 200/240 V drive systems without a separate variant.
Mechanical and encoder interface
The shaft is a plain cylindrical D14 x 30 mm stub — a standard dimension for coupling or pinion mounting on small-format axes such as tabletop conveyors, indexing tables, and feeder drives. Feedback is an absolute encoder AS22DQC at 22-bit single-turn resolution read over the drive-side OCC interface, which is the high-speed single-cable connection on the S210 system; the cable carries both power and encoder signals through one M17 rotatable plug, simplifying the cable run when the cabinet layout forces an awkward approach angle. IP64 ingress protection on the housing means the motor tolerates dust and light splashing but is not rated for direct washdown — for food-grade or outdoor wet areas a higher-rated 1FK2 variant is the correct substitution.
Compliance and order mechanics
The motor is RoHS-compliant since 01-07-06 and carries the REACH Art. 33 duty to inform — the manufacturer publishes candidate-list substance data through the standard Reach Information channel.
Sourcing posture
Lifecycle status is recorded as active, so the BOM position is specifiable today — for volume requirements the part is quoted against the order quantity with lead time confirmed at RFQ, consistent with a configured made-to-order motor line.
