On a 200-240 V drive bus the same motor delivers PN=0.2 kW at nN=1500 rpm, which is the so-what of the dual-voltage rating: one part number covers both 400 V-class SINAMICS S120 cabinets and 230 V-class S120 line modules without a re-spec. ## Mechanical face, brake, and feedback The shaft is D19x40 mm with a feather key and the housing is IP64, which is adequate for dry, dust-controlled cabinets but not for washdown — that gap matters when this part is being scoped for any food, beverage, or outdoor enclosure. Feedback is an absolute encoder single-turn 22-bit (AS22DQC) over DRIVE-CLiQ on an M17 plug, and the power lead terminates at an M17 power connector, so the field-replaceable side of the axis is the cable set rather than the feedback device itself. ## Lifecycle, compliance, and ERP fields Group Code R220 and Product Group 9021 are the internal identifiers carried on the line, which is what an ERP record will key on for the BOM entry.","metaTitle":"Siemens 1FK2104-4AF10-1SB0 servo motor, 0.4 kW, with brake","metaDescription":"Siemens 1FK2104-4AF10-1SB0 SIMOTICS S-1FK2 HD servo, M0=1.27 Nm, 0.4 kW at 3000 rpm (380-480 V), with holding brake, IP64, DRIVE-CLiQ.
