Siemens 1FK2103-4AG00-2SA0 SIMOTICS S-1FK2 HD 1.27 Nm 0.4 kW Servo Motor

The Siemens 1FK2103-4AG00-2SA0 is a SIMOTICS S-1FK2 HD synchronous servo motor with 1.27 Nm standstill torque, rated 0.4 kW at 3000 rpm on a 200-240 V supply. It carries an absolute single-turn 22-bit encoder (AS22DQC) over a single OCC feedback cable and is matched to the SINAMICS S210 single-axis servo drive.

Selection Notes

At 1.27 Nm standstill torque, this is the higher-torque winding of the two 1FK2103 HD variants on 200-240 V supply, roughly double the torque of the lower step in the same frame size and mounting footprint. The OCC cable combines power and absolute feedback in one run, which simplifies cable management on the SINAMICS S210 axis compared with a two-cable motor. Because the AS22DQC encoder is single-turn absolute, the drive resolves position within one revolution at power-up; multi-turn indexing axes still require a homing sequence. The M12 connector rotates, so cable exit direction can be set on the machine rather than fixed at manufacture.

Applications

Suits small conveyor drives, pick-and-place axes, and light indexing stations on a SINAMICS S210 servo drive where 200-240 V supply is available. IP64 handles dust and splash from any direction but not washdown or submersion.
