Siemens 1FL6092-1AC61-2LA1 Permanent-Magnet Synchronous Servo Motor – SIMOTICS S-1FL6 Series
When a servo axis loses its drive motor on a production line, the consequences are immediate and costly: the entire machine halts, downstream processes back up, and every minute of unplanned downtime erodes both output and margin. In high-precision applications—CNC machining centers, packaging lines, or robotic assembly cells—there is no acceptable substitute for the exact motor the system was engineered around. The Siemens 1FL6092-1AC61-2LA1 is that motor: a purpose-built, permanent-magnet synchronous servo motor designed to restore full axis performance without compromise.
Within the SIMOTICS S-1FL6 family, the 1FL6092-1AC61-2LA1 occupies the high-inertia, medium-frame segment—shaft height 90 mm, natural-cooled construction, with a 23-bit absolute encoder (Hiperface DSL single-turn) and a holding brake. This combination makes it the preferred choice for axes that demand precise positioning, smooth torque delivery at low speed, and safe standstill holding. Globally, the SIMOTICS S-1FL6 series is one of Siemens’ most widely deployed servo platforms, fully integrated with SINAMICS S120 and S210 drive systems and supported by TIA Portal engineering.

Key Features & Benefits
- High-Inertia Rotor Design: Optimized for axes with large load inertia ratios, reducing mechanical resonance and enabling stable control without complex filter tuning.
- 23-Bit Absolute Encoder (Hiperface DSL): Single-cable technology combines power and encoder signals, simplifying wiring and improving noise immunity. Absolute position is retained on power-down—no homing cycle required at startup.
- Integrated Holding Brake: Provides safe mechanical standstill holding for vertical axes or safety-critical applications, reducing reliance on external brake hardware.
- Seamless TIA Portal Integration: Drive and motor parameters are auto-identified via DRIVE-CLiQ-compatible encoder protocol, dramatically reducing commissioning time.
- Natural Cooling: No external fan required, eliminating a common failure point and reducing maintenance intervals in dusty or humid environments.
- IP64 Protection: Suitable for environments with moderate dust and splash water exposure, common in machine tool and food-adjacent applications.
Industry & Equipment Applications
- CNC Machine Tools: Feed axis and spindle positioning on machining centers, lathes, and grinding machines.
- Packaging Machinery: High-speed pick-and-place, form-fill-seal, and cartoning lines requiring precise torque and position control.
- Robotics & Handling: Joint drives in Cartesian gantries and SCARA robots where high inertia matching is critical.
- Printing & Converting: Register control and tension management on web-fed printing presses and slitter-rewinders.
- Semiconductor & Electronics Manufacturing: Precision stage drives in wafer handling and PCB drilling equipment.
- Plastics & Injection Molding: Clamp and injection axis drives on all-electric injection molding machines.

Frequently Asked Questions
Q: Is the 1FL6092-1AC61-2LA1 compatible with SINAMICS S210?
A: Yes. The SIMOTICS S-1FL6 series is fully compatible with SINAMICS S210 single-axis servo drives. The Hiperface DSL encoder protocol is natively supported, enabling single-cable connection and automatic motor identification.
Q: What does the “2LA1” suffix indicate in the part number?
A: In Siemens’ ordering nomenclature for the 1FL6 series, the suffix encodes options such as encoder type, brake configuration, shaft and flange variant, and vibration class. “2LA1” specifies the 23-bit absolute single-turn Hiperface DSL encoder with integrated holding brake and standard shaft/flange. Always verify the full order number against the Siemens configurator for your specific application.
Q: Can this motor be used as a direct replacement for an older 1FK7 or 1FT7 motor?
A: The 1FL6 series is not a direct drop-in replacement for 1FK7 or 1FT7 motors due to differences in flange dimensions, encoder protocol, and drive parameterization. A compatibility assessment by a qualified Siemens drive engineer is required before substitution.
Q: Do you provide a warranty on this product?
A: We offer a standard inspection warranty covering physical and nameplate integrity. For operational warranty, we recommend purchasing through an authorized Siemens channel. Contact us for details on our quality guarantee terms.
Q: What is the typical lead time for the 1FL6092-1AC61-2LA1?
A: Lead time depends on current stock availability. Please submit an RFQ for a real-time availability check. In-stock units typically ship within 3–5 business days after order confirmation.
