Siemens 1FK2104-5AK00-0SA0 SIMOTICS S-1FK2 HD 2.4 Nm 1.07 kW Servo Motor

The Siemens 1FK2104-5AK00-0SA0 is a SIMOTICS S-1FK2 HD synchronous servo motor with 2.4 Nm standstill torque, dual-rated 1.07 kW at 6000 rpm on 380-480 V and 0.75 kW at 3000 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.

Technical Specifications

Selection Notes

This motor is dual-rated by supply voltage: on 380-480 V the SINAMICS S210 can run it to 6000 rpm for 1.07 kW, while a 200-240 V supply caps it at 3000 rpm and 0.75 kW at the same 2.4 Nm torque. Pick the higher-voltage line-up when the application needs the extra speed headroom; the lower-voltage option is enough where the axis never exceeds 3000 rpm. The single OCC cable carries power and absolute feedback together, cutting one cable run versus a split power/encoder motor. The single-turn AS22DQC encoder resolves position within one revolution at power-up, so multi-turn indexing axes still need a homing move. The larger D19 x 40 mm shaft and M17 rotatable connector are a step up from the 1FK2103 frame, in line with the higher torque and power.

Applications

Sized for indexing tables, small robots, and conveyor axes that need speed above 3000 rpm when run from a 380-480 V SINAMICS S210 supply. IP64 handles dust and splash from any direction, not washdown or submersion.
