Active production, SINAMICS S210 motor
The part 1FK2104-5AK11-1MA0 is listed as Active in production and belongs to the 1FK2 servomotor family built for the SINAMICS S210 drive platform. It carries a holding brake and is rated at M0 = 2.4 Nm with PN = 1.07 kW at nN = 6000 rpm on a 380-480 V supply, or PN = 0.75 kW at nN = 3000 rpm on a 200-240 V supply. The shaft is D19 x 40 mm with feather key, the encoder is the 22-bit + 12-bit multiturn absolute AM22DQC, and the M17 power/signal connector is rotatable for cabinet routing flexibility. Degree of protection IP65 on the housing with the matching connector mated means the motor tolerates cabinet-adjacent installation and incidental splash — typical for machine-builder panels where the drive sits outside the sealed enclosure. The OCC (one-cable connection) interface consolidates power and encoder signalling through the single M17 plug, which simplifies the cabinet gland plate and reduces the wiring error surface during commissioning.
What the headline ratings drive in a BOM line
PN = 1.07 kW at nN = 6000 rpm on 380-480 V sets the sizing ceiling for sizing-class sizing — the lower PN = 0.75 kW rating on 200-240 V reflects the derated continuous torque available from the same frame at reduced DC-bus voltage. This matters when the cabinet is wired for 230 V regional supply: the motor still runs, but the continuous power ceiling drops from 1.07 kW to 0.75 kW before thermal limits engage. The AM22DQC absolute encoder (22-bit singleturn + 12-bit multiturn) eliminates the need for a referencing routine on power-up — position survives across power cycles, which shortens machine-restart time after E-stop or mains loss. M0 = 2.4 Nm defines the static holding torque the motor delivers at zero speed, the figure that governs whether the integrated holding brake can hold a vertical axis against gravity without slip.
Compliance and documentation on record
RoHS compliance has been declared since 01-07-06, and the part is subject to REACH Art. 33 information duty with the current candidate-list update flow through Siemens Reach Information. Export Control Regulations classify the product AL:N / ECCN:N_CNDU — a clean EAR99-equivalent export class that does not require a license for typical industrial destinations. The order code carries Group Code R220 within Product Group 9021 in the Siemens ordering system, which is the internal reference the buyer quotes into Siemens configurators and the surcharge/freight tables. Product class is C: built to order, non-returnable, non-reusable — so a wrong specification in the BOM line cannot be returned for credit; the rating selection has to be locked before the order releases.
Sourcing posture for this build-to-order line
Because product class C makes every unit built to order with no return path, the procurement move is to lock the BOM line against the Siemens configurator output (order code, encoder variant, brake option, connector orientation) before issuing the RFQ — mismatches on the encoder code or connector size cannot be reworked post-build. Quantity unit is 1 piece, packaging quantity 1, with the shipping carton at 452.00 x 250.00 x 267.00 mm — a single-motor pack rather than a multi-unit case. Same part, different passport — what changes between regional authorized sources is the warranty geofencing and the response-time SLA, not the motor itself; the bill-of-materials and the AM22DQC encoder are identical across factory-allocated channels, and we move genuine OEM stock through independent distribution against an RFQ rather than through a single authorized-channel wall.
