Siemens 1FK2103-2AG00-2SA0 SIMOTICS S-1FK2 HD 0.64 Nm 0.2 kW Servo Motor

The Siemens 1FK2103-2AG00-2SA0 is a SIMOTICS S-1FK2 HD synchronous servo motor with 0.64 Nm standstill torque, rated 0.2 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.

Technical Specifications

Selection Notes

M0 = 0.64 Nm places this motor at the low-torque end of the 1FK2-HD line, sized for light-load, high-dynamic point-to-point motion rather than continuous heavy loading. The single OCC cable carries power and absolute position feedback together, removing one cable run compared with motors that use a separate encoder cable. The encoder is single-turn absolute, so the SINAMICS S210 knows shaft position within one revolution at power-up but not across multiple turns; axes that index past one full turn still need a homing move. The rotatable M12 connector lets the cable exit be set during installation instead of being fixed at the factory. For more torque in the same 1FK2103 frame, the next winding step up roughly doubles standstill torque without changing the mounting footprint.

Applications

Fits compact pick-and-place axes, small parts handling, and light indexing stages run from a SINAMICS S210 servo drive. IP64 covers dust and splashing from any direction on a machine floor, but the motor is not rated for washdown or submersion.
