A compact HD servo paired to a SINAMICS S210 drive
The 1FK2104-4AK10-2MA0 is a SIMOTICS S-1FK2 HD servo motor from the 1FK2 family intended for direct pairing with a SINAMICS S210 drive system, supplied with an integrated holding brake so a vertical or gravity-loaded axis holds position when the drive stage is de-energised. It belongs to product group 9021 under group code R220 and ships as one piece per orderable unit, a built-to-order configuration that cannot be returned against credit once delivered.
1.27 Nm stall, 0.6 kW — what the electrical envelope buys
The motor delivers a stall torque M0 of 1.27 Nm with a rated power PN of 0.6 kW at a rated speed nN of 6000 rpm on the 380–480 V supply rail and 0.4 kW at 3000 rpm on the 200–240 V supply, giving the panel designer one part number that can be commissioned on either voltage class typical of a SINAMICS S210 cabinet. Feedback is an absolute encoder AM22DQC at 22-bit single-turn plus 12-bit multi-turn resolution, so the drive retains absolute position across power cycles and the OCC interface passes drive-side comms through the same M17 rotatable plug — a single connector for power, brake and signal on a modest-format axis.
IP64, cylindrical shaft D14 x 30 mm — the mechanical envelope
The shaft is a cylindrical D14 x 30 mm stub, which is the standard format for a planetary gearbox input or a direct pinion/belt coupling on a small-format axis — not a keyed profile, so the load-side hub must be clamp or shrink-fit only. Degree of protection is IP64 with a sealing concept that tolerates light dust ingress and water spray from any direction but is not rated for full washdown, so the motor typically sits inside the machine envelope or under a guard rather than in a food-and-bev splash zone.
Lifecycle status and the sourcing channel
Because product class C defines this motor as built-to-order that cannot be returned against credit, stock positions are typically project-allocated rather than off-the-shelf shelf stock — independent distribution quotes against the BOM quantity and confirms lead time and pricing at RFQ.
Compliance paperwork that travels with the motor
RoHS compliance is declared on the Siemens record since 2006-07-01, and REACH Article 33 duty-to-inform applies against the current candidate list — the buyer receives the standard Siemens reach information sheet rather than a separate certificate on each shipment. Export control is ECCN N_CNDU under AL designation N, meaning no export licence is required for routine commercial shipment of this motor from the manufacturer to the destination.
