It ships with an integral holding brake, IP64 sealing, a D19x40 mm keyed shaft, a single-turn 22-bit absolute encoder (AS22DQC), and a DRIVE-CLiQ feedback plug plus M17 power connector — the standard pairing for a SINAMICS S120 booksize or blocksize axis on the machine side. Catalog metadata flags the part as Group Code R220, Product Group 9021, packaging quantity 1 Piece, and product class C — the class meaning the unit is built to order and not returnable. That classification is the procurement reality behind the listing: every motor is wound, encoder-aligned and brake-set against a fresh works order, so the lead-time clock starts on the RFQ, not the shelf. Lifecycle reads as Active per the catalog stage. ## Reading the nameplate string for fit The dual-voltage power rating (0.6 kW at 6000 rpm on 380-480 V versus 0.4 kW at 3000 rpm on 200-240 V) tells the panel designer which SINAMICS line to pair it with: the higher figure goes with a 400 V-class drive on a three-phase industrial bus, the lower with a 230 V-class drive in a lighter machine or North-American 240 V coil. Sizing the drive to the lower of the two ratings would under-utilize the motor at the higher bus voltage; sizing to the higher figure would exceed the motor's continuous thermal envelope on a 230 V-only axis. The 22-bit single-turn absolute encoder (AS22DQC) gives 4,194,304 counts per revolution — fine enough for high-dynamic positioning without battery backup, which suits rotary axes where an absolute reference is established only at commissioning. The DRIVE-CLiQ plug means the motor auto-identifies on the SINAMICS drive: electronic nameplate, encoder parameters and brake logic load automatically, no manual parameter entry. ## Compliance trail the buyer will be asked for REACH Article 33 information is published for the current candidate-list substances; the dossier is the document to attach when the OEM's compliance pack is requested. That keeps the cross-border paperwork short for an integrator shipping machines into North America, the EU and most of Asia-Pacific. ## How it lands against the typical SINAMICS pairing The three peer order codes in the catalog all sit in Product Group 9775 (Air-cooled Power Modules in blocksize format) with packaging footprint 495 x 356 x 300 mm — these are the SINAMICS S120 booksize / blocksize drive modules the 1FK2104-4AK10-1SB0 typically drives, not motor alternatives. A panel specified around any of those drives pairs to this motor through the DRIVE-CLiQ cable and M17 power lead, not as a drop-in replacement.","metaTitle":"Siemens 1FK2104-4AK10-1SB0 SIMOTICS S-1FK2 HD servo motor","metaDescription":"Siemens 1FK2104-4AK10-1SB0 SIMOTICS S-1FK2 HD servo, 0.6 kW at 6000 rpm, with holding brake and DRIVE-CLiQ.
