Form-factor and shaft reality
The 1FK2104-5AF11-1SA0 ships as a SIMOTICS S-1FK2 HD servo with a D19x40 mm feather-keyed shaft, an absolute encoder single-turn 22-bit (AS22DQC) on the rear, and an M17 plug that rotates to match the cabinet routing on install. Holding brake is integrated, degree of protection is IP65 across the body and shaft seal, and the interface is the OCC connector on the SINAMICS S210 drive side — the servo is sized for the S-1FK2 high-dynamic family rather than legacy 1FK7 panels.
Power envelope at the two voltage rails
Rated 0.75 kW at nN=3000 rpm on the 380–480 V three-phase rail, the motor covers the standard S210 line input; the lower PN=0.375 kW figure at nN=1500 rpm holds for the 200–240 V rail, which is the figure to verify against the cabinet feed before the BOM is frozen. Stall torque M0=2.4 Nm sets the lower bound on gearbox sizing — pairing the 1FK2 HD frame to a gearbox with a continuous torque rating below that figure starves the drive on every accel ramp.
Mounting, sealing, and panel integration
IP65 on the shaft seal and housing lets the servo sit adjacent to coolant spray and mild washdown — the M17 connector's rotatable plug and OCC interface mean the cable dress follows the cabinet, not the other way around, so layout planning only needs to leave service loop for the encoder tail. Packaging is a single piece per shipper at 452.00 x 250.00 x 267.00 mm — single-unit pack-out, so staging needs shelf space for the factory carton rather than a multi-up tray.
Lifecycle, compliance, and the build-to-order reality
Lifecycle stage is current; the part is on the customer's AVL as an active Siemens servo for the SINAMICS S210 platform — no deviation needed when the build sheet already names 1FK2104-5AF11-1SA0.
