Part definition and drive pairing
The 1FK2104-4AK11-1MB0 is a SIMOTICS S-1FK2 HD servo motor out of the 1FK2 servomotors for SINAMICS S120 family, built around a holding brake, an IP65 housing, and a DRIVE-CLiQ plug M17 plus a size M17 power connector — the conventional pairing when the drive side is a SINAMICS S120 module on a multi-axis machine.
Rated torque, speed, and the two voltage bands
Stall torque M0 is 1.27 Nm; rated power PN is 0.6 kW at nN=6000 rpm on a 380-480 V supply, and PN is 0.4 kW at nN=3000 rpm on a 200-240 V supply, so the same motor covers both the European 400 V class and the 230 V class line by re-scaling the speed/power point — relevant when retrofitting a 230 V machine onto a 400 V cabinet. The shaft is D19 x 40 mm with feather key, which sets the mechanical interface to the gearbox or coupling on the driven axis; the IP65 rating covers the body sealing against coolant splash and cutting mist typical on a tool-making cell.
Feedback loop and connector stack
Feedback is the absolute encoder AM22DQC at 22-bit singleturn plus 12-bit multiturn, returned over DRIVE-CLiQ to the SINAMICS S120 — the resolution and commutation data ride the same cable back to the drive, which is what keeps the position loop deterministic to the cycle and avoids a separate battery box for the absolute track.
Compliance and export class
The motor has been RoHS-compliant since 01-07-06 and is flagged for REACH Art. 33 candidate-list duty to inform; export control is AL:N with ECCN:N_CNDU, so cross-border shipment does not require an export licence under the listed classification.
Commercial identifiers
Commercial identifiers on the record are Group Code R220 and Product Group 9021; the line is classed as a custom-built product manufactured to order (product class C) and ships as a single piece per quantity unit — standard for a configured servo with a specific shaft, brake, and encoder combination.
