Siemens 1FK2206-4AF00-0SA0 SIMOTICS S-1FK2 CT 12 Nm 2.85 kW Servo Motor

The Siemens 1FK2206-4AF00-0SA0 is a SIMOTICS S-1FK2 CT synchronous servo motor with 12 Nm standstill torque, dual-rated 2.85 kW at 3000 rpm on 380-480 V and 1.72 kW at 1500 rpm on 200-240 V. It uses an absolute single-turn 22-bit encoder (AS22DQC) over a single OCC feedback cable, matched to the SINAMICS S210 servo drive.

Selection Notes

This is a 1FK2-CT motor rather than the HD line used by the smaller 1FK2103/1FK2104/1FK2105 frames, built for continuous torque at 12 Nm in a larger D24 x 50 mm shaft and M23 connector size. As with the smaller dual-voltage 1FK2 motors, the 380-480 V rating doubles both speed and power versus 200-240 V at the same 12 Nm torque, so the supply voltage should be chosen against the axis speed target. The OCC cable combines power and absolute feedback in one run, and the single-turn AS22DQC encoder resolves position within one revolution at power-up, so multi-turn indexing axes still need a homing move.

Applications

Sized for higher-load conveyor drives, larger indexing tables, and robotic joints that need more continuous torque than the 1FK2 HD frames, run from a SINAMICS S210 servo drive. IP64 covers dust and splash from any direction, not washdown or submersion.
