Where this motor drops into the cabinet
The 1FK2104-6AF10-1SB0 is a SIMOTICS S-1FK2 HD servo motor from the 1FK2 servomotors family, sized to pair with a SINAMICS S120 drive module on a positioning or feed axis. It ships with a holding brake, an absolute single-turn 22-bit encoder (AS22DQC), DRIVE-CLiQ via an M17 plug for the feedback path, and an M17 power connector — the standard cabling layout a controls integrator expects when dropping a 1FK2 onto an S120 line-up.
Two voltage windows for the same rating
Rated output is 1 kW at nN=3000 rpm when fed from a 380-480 V SINAMICS line, or 0.5 kW at nN=1500 rpm on a 200-240 V line; the holding torque M0 is 3.2 Nm in either case. That dual-band rating matters on retrofit jobs where the existing drive cabinet is 230 V and the axis upgrade targets a 400 V supply — the same motor covers both without re-engineering the mechanical side.
Shaft, sealing and feedback at the motor face
The shaft is D19x40 mm with feather key, IP64 on the housing — an industrial-panel-grade sealing class suited to inside-cabinet or light-dust environments, not washdown. The AS22DQC 22-bit single-turn absolute encoder returns position via DRIVE-CLiQ, so the drive auto-identifies the motor on first power-up and pulls the electronic nameplate from the encoder — no manual parameter entry for the motor data.
Lifecycle status and procurement reality
Lifecycle status reads current on the official record, and the Group Code R220 / Product Group 9021 identifiers place it inside the standard Siemens motion-control catalog flow. Product class is C — manufactured to order with no return or reuse credit — so any RFQ needs to land on the right quantity the first time; we source against the BOM line you commit to and confirm availability at quote. Compliance carries RoHS conformity since 01-07-06, and the part falls under REACH Art. 33 duty-to-inform when a candidate-list substance is present; the REACH information sheet is supplied with the shipment.
