Siemens 1FK7063-5AF71-1SH0 – Compact AC Servo Motor for High-Dynamic Motion Control | SIMOTICS S Series
Engineering Background
The Siemens 1FK7 series represents the benchmark in compact permanent-magnet synchronous servo motors within the SIMOTICS S platform. Designed for seamless integration with SINAMICS S120 and S210 drive systems, the 1FK7063-5AF71-1SH0 delivers high torque density, precise encoder feedback, and robust thermal management — making it the preferred choice for demanding motion-control applications in machine tools, packaging lines, and robotics.
Product Positioning
The 1FK7063-5AF71-1SH0 is a mid-frame (63 mm flange) servo motor optimized for applications requiring fast dynamic response, smooth velocity control, and reliable positioning accuracy. It ships with a multi-turn absolute encoder (Hiperface/EnDat compatible) and a natural-convection cooling design, reducing installation complexity while maintaining full rated torque across the operating speed range.

- Compact 63 mm Frame – Fits space-constrained machine designs without sacrificing rated torque
- IP64 Sealing – Suitable for environments with coolant mist and light wash-down
- Low Cogging Torque – Smooth velocity control at low speeds for precision contouring
System Architecture & Signal Flow
The 1FK7063-5AF71-1SH0 integrates into a SINAMICS S120 booksize or chassis drive system via a single-cable or dual-cable connection topology:
- Power Cable – 3-phase motor power (U, V, W) + PE ground from Motor Module output
- Encoder Cable – Hiperface or EnDat 2.2 signal cable to Sensor Module Cabinet-Mounted (SMC) or direct DRIVE-CLiQ interface
- DRIVE-CLiQ – Digital drive bus carries motor nameplate data, temperature feedback, and encoder values on a single RJ45 connector (when SMC is used)
- Control Unit (CU320-2) – Executes position, velocity, and torque control loops; communicates with PLC via PROFINET/PROFIBUS
- PLC Integration – SIMATIC S7-1500 / S7-300 issues motion commands via TIA Portal with S7-Technology or SIMOTION D

Technical FAQ
Q: Is the 1FK7063-5AF71-1SH0 compatible with SINAMICS S210?
A: Yes. The S210 single-axis drive supports 1FK7 compact motors with EnDat 2.2 encoder via the integrated motor connector. Verify firmware version ≥ V5.1 for full feature support.
Q: What is the difference between 1SH0 and 1SH3 shaft variants?
A: 1SH0 = smooth shaft with featherkey groove; 1SH3 = shaft with keyway and key fitted. Both are mechanically interchangeable in most coupling designs.
Q: Can this motor operate without a SINAMICS drive?
A: No. The 1FK7 series requires a compatible servo drive for commutation. It cannot be run on a standard VFD or direct-on-line starter.
Q: What encoder cable length is supported?
A: Standard Siemens pre-assembled encoder cables support up to 75 m. For longer runs, use a signal repeater or fiber-optic DRIVE-CLiQ extension.
Q: Do you provide the STARTER / TIA Portal project file for commissioning?
A: We can provide a sample TIA Portal V17/V18 project template with basic axis configuration on request. Contact our technical team.
