Why Engineers Specify This Model
- High Torque Density — The 1FK7 Compact series delivers exceptional torque-to-volume ratio, enabling machine designs with smaller motor compartments without sacrificing dynamic performance.
- Absolute Encoder Standard — The -1RH1 suffix confirms an integrated absolute encoder, eliminating homing routines on power-up and improving machine availability.
- Seamless SINAMICS Integration — Native compatibility with SINAMICS S120 and V90 drives enables plug-and-play commissioning via DRIVE-CLiQ, reducing engineering hours.
- Proven Reliability — Siemens SIMOTICS S motors are deployed in millions of axes globally, with documented MTBF exceeding 50,000 hours in standard industrial environments.
- Scalable Architecture — The 1FK7 family spans a wide torque range, allowing engineers to standardize on one motor family across multiple machine axes.
Complete System Bill of Materials
For a fully operational servo axis using the 1FK7063-2AF71-1RH1, the following components are typically required:
- Servo Drive: SINAMICS S120 Motor Module (e.g., 6SL3120-1TE21-0AA3) or SINAMICS V90 (6SL3210-5FB10-4UA0)
- Control Unit: SINAMICS S120 CU320-2 DP/PN (6SL3040-1MA01-0AA0)
- Power Module / Line Module: SINAMICS S120 Active Line Module (size-dependent)
- Motor Cable: Siemens pre-assembled power cable (MOTION-CONNECT 500/800 series)
- Encoder Cable: DRIVE-CLiQ cable or resolver cable (MOTION-CONNECT 800PLUS)
- Brake Resistor: Required if regenerative braking energy cannot be fed back to grid
- Coupling / Gearbox: Application-dependent (e.g., SIMOGEAR bevel-helical gearbox)
- Safety Option: SMC30 or SME120 for STO/SS1 safety functions (SIL 2 / PLd)

Application-Specific FAQ
Q: Is the 1FK7063-2AF71-1RH1 compatible with SINAMICS V90?
A: Yes. The 1FK7 Compact series is fully compatible with SINAMICS V90 drives. Use Siemens SIZER or the V90 selection tool to confirm the correct drive size for your load profile.
Q: What does the suffix “2AF71” indicate?
A: The suffix encodes the motor’s electrical variant — specifically the winding configuration (2A = 400V class, F = specific winding), encoder type (7 = absolute encoder), and mechanical options (1 = standard flange). Always decode the full order number using the Siemens 1FK7 catalog.
Q: Can this motor be used in a vertical axis application?
A: Yes, with appropriate consideration for holding brake requirements. The -1RH1 suffix does not include an integrated brake. If the load must be held at standstill (e.g., vertical Z-axis), specify a variant with brake suffix or add an external holding brake.
Q: What is the lead time for this part?
A: Lead time varies by stock availability. Contact us at support@konmask.com for real-time stock status. We maintain buffer stock of common 1FK7 variants for fast delivery.
Q: Do you provide a warranty?
A: Yes. We provide a 12-month warranty against manufacturing defects on all genuine Siemens products supplied by Konmask.com, subject to correct installation and operating conditions.
