Holding-brake servo for a SINAMICS S210 axis
The 1FK2104-5AF10-0SA0 is a SIMOTICS S-1FK2 HD servo motor out of the 1FK2 family intended for SINAMICS S210 drives, with a holding brake built in so the axis stays parked when the converter is de-energised (cites:,). Stated output is PN 0.75 kW at nN 3000 rpm on a 380-480 V bus, with a secondary rating of PN 0.375 kW at nN 1500 rpm on a 200-240 V bus, so the same frame can be deployed on either mains region by selecting the matching S210 line input (cites:). The motor carries an absolute encoder single-turn 22-bit (AS22DQC) and an OCC interface on a rotatable M17 plug — the encoder resolution sets the position-loop quantisation at the drive, and the rotatable connector keeps the cable dress flexible across mounting orientations (cites:). Mechanical build is a cylindrical shaft D19x40 mm with IP64 sealing, suited to indoor cabinet-side mounting where occasional wipe-downs are expected but full washdown is not required (cites:).
Compliance paperwork to chase before shipping
Siemens marks the part as compliant with the RoHS substance restrictions since 01-07-06 and flags REACH Art. 33 duty-to-inform against the current candidate list, so the declaration pack should carry both statements at the time of order (cites:,). Orderable as one piece per Quantity Unit, in a packaging footprint of 452.00 x 250.00 x 267.00 mm — relevant when planning courier dimensions for a repair swap or a panel-builder kit (cites:,). Export Control Regulations are listed as AL: N / ECCN: N_CNDU, which keeps cross-border paperwork light; the product class note confirms the unit is produced to order and is not returnable against credit, so the BOM line must be firm before release (cites:,).
Production status and how to source it
Siemens internal references Group Code R220 and Product Group 9021 — useful when matching a PO line against the vendor's own classification during goods-in or warranty handling (cites:,). Build-to-order terms rule out a cancelled-and-return path, so the practical move is to confirm quantity and ship-to against an RFQ and let the supplier lock the production slot; we source against independent distribution channels and quote current pricing at quote time.
