1 kW at 3000 rpm — the duty bands this motor commits to
Specified as a SIMOTICS S-1FK2 CT servo motor from the 1FK2 family for SINAMICS S120, the 1FK2204-6AF11-1SB0 runs two stacked power ratings on the same frame: P_N = 1 kW at n_N = 3000 rpm on a 380-480 V supply, and P_N = 0.5 kW at n_N = 1500 rpm on a 200-240 V supply. Stating both bands in one order code is what lets the same motor sit on a 400 V European line and a 230 V North American line without a rewiring step. The M0 = 3.2 Nm rated continuous torque anchors the low-speed sizing — once the mechanical cycle asks for more dwell torque than 3.2 Nm the next frame size is the answer, not a higher current setting. Underrated torque at low speed is the silent failure mode on a feed axis sized for productivity, not holding.
Encoder, brake, sealing — the stack that decides a cabinet decision
The feedback path is an absolute encoder single-turn 22-bit (AS22DQC) talking back over a DRIVE-CLiQ M17 plug. That combination is what locks the axis into the S120 drive's distributed-clock frame: cyclic process data, zero additional parameter page for the encoder, and position samples that line up with the bus cycle rather than the motor's own quadrature period. A holding brake ships in the build, and the IP65 rating on the body lets the motor sit in cabinets near a panel door or in machinery rooms where occasional condensate or oil mist reaches the housing — sealed against ingress, not rated for direct jet washdown. Shaft is D19 x 40 mm with feather key, mated to the customer's coupling or gearbox on the load side.
