SIEMENS 1FL6044-1AF61-2AA1 — Low-Inertia Synchronous Servo Motor | SINAMICS S210 Platform
Engineering Background
The SIEMENS SIMOTICS S-1FL6 series represents Siemens’ dedicated servo motor family engineered for high-dynamic motion control applications. The 1FL6044-1AF61-2AA1 is a compact, low-inertia synchronous AC servo motor optimized for pairing with the SINAMICS S210 single-axis servo drive system — a fully integrated, one-cable solution that eliminates separate encoder wiring and dramatically simplifies cabinet design.
Product Positioning
Designed for OEM machine builders and system integrators requiring precise torque control, fast dynamic response, and minimal footprint. Ideal for axes demanding high cycle rates, tight positioning repeatability, and deterministic motion — from packaging and printing to semiconductor handling and precision assembly.

Proven Application Environments
- Packaging Machinery — High-speed pick-and-place, form-fill-seal, and cartoning lines requiring sub-millisecond torque response
- Printing & Converting — Register control, tension management, and web guiding on narrow-web and wide-format presses
- Semiconductor & Electronics Assembly — Die bonding, wafer handling, and SMT placement where micron-level repeatability is mandatory
- CNC Machine Tools — Feed axis and tool-changer drives on machining centers and grinding machines
- Robotics & Collaborative Arms — Joint actuators in SCARA and Cartesian robots with compact axis envelopes
- Medical & Laboratory Automation — Pipetting, dispensing, and diagnostic instrument axes requiring clean, low-noise operation
Engineering Advantages
- One-Cable Technology (OCT) — Combines motor power and 22-bit absolute encoder feedback in a single hybrid cable, reducing wiring cost by up to 40% and eliminating encoder connector failure points
- Low Rotor Inertia — 0.57 × 10⁻³ kg·m² enables rapid acceleration/deceleration cycles, maximizing throughput on high-cycle applications
- Plug-and-Play with SINAMICS S210 — Electronic nameplate (DRIVE-CLiQ equivalent via OCT) allows automatic motor identification; no manual parameter entry required
- IP65 Sealing — Suitable for wash-down adjacent environments and dusty production floors without additional enclosure
- Compact 60 mm Flange — Minimizes machine footprint while delivering 3.5 Nm continuous torque, enabling dense multi-axis configurations
- Vibration-Resistant Design — Rated to 50 m/s² per EN 60068-2-6, suitable for press-adjacent and mobile machine installations
System Architecture & Signal Flow
The 1FL6044-1AF61-2AA1 operates within the SINAMICS S210 closed-loop servo system as follows:
- Controller (PLC/CNC) — Issues position/velocity/torque setpoints via PROFINET IRT or pulse-direction interface to the S210 drive
- SINAMICS S210 Drive — Executes current control loop at 62.5 µs cycle; generates PWM output to motor phases
- OCT Hybrid Cable — Carries 3-phase power (U/V/W) + 24 V encoder supply + absolute position data (22-bit, single-turn) in one cable run
- 1FL6044-1AF61-2AA1 Motor — Converts electrical energy to mechanical torque; encoder reports absolute shaft position back to drive on every scan cycle
- Load / Mechanical Transmission — Ballscrew, rack-and-pinion, or belt drive connected via smooth shaft (coupling or clamp hub recommended)
No separate encoder cable, no DRIVE-CLiQ box required — the OCT interface handles all feedback natively within the S210 ecosystem.

Technical FAQ
Q: Is the 1FL6044-1AF61-2AA1 compatible with SINAMICS S120?
A: No. The 1FL6 series with OCT interface is exclusively designed for SINAMICS S210. For S120 systems, the corresponding motor family is SIMOTICS S-1FK7 or 1FT7 with DRIVE-CLiQ encoder.
Q: Can I add a holding brake to this variant?
A: The -2AA1 suffix indicates no brake. The brake variant is 1FL6044-1AF61-2LB1. Konmask stocks both — contact us to confirm availability.
Q: What cable length is recommended for OCT connection?
A: SIEMENS specifies a maximum OCT cable length of 25 m for the S210 system. Standard pre-assembled cable sets (6FX3002-5CL12-xxxx) are available in 3, 5, 10, 15, 20, and 25 m lengths.
Q: What is the shaft diameter and length?
A: Shaft diameter is 14 mm (h6 tolerance), usable shaft length 30 mm. A featherkey groove is absent on the -AA1 smooth shaft variant.
Q: Is this motor RoHS compliant?
A: Yes. The 1FL6 series is fully RoHS 2 (Directive 2011/65/EU) compliant.
Q: Can Konmask provide the SINAMICS S210 drive to match?
A: Yes. We supply the complete S210 single-axis drive family. Specify your supply voltage (1AC 200V or 3AC 400V) and we will recommend the correct drive order number.
