SIEMENS

I. Product Model Series
This is the Siemens SIMOTICS S 1FK7 compact synchronous servo motor. The typical order model examples corresponding to the appearance in the picture are:
1FK7042-2AF71-1UB0, 1FK7060-2AH71-1UA0, etc. All the appearance identical models belong to the 1FK7 product line, with only power, encoder, and brake configuration differing.
Appearance identification features
Full metal silver-gray integrated casing, square flange installation;
Integrated aviation plug (power red plug + encoder integrated together);
Compact modular structure, it is the main series of Siemens mid-range high-precision servo motors.
II. Core Positioning and Matching Drives
Matching drive: SINAMICS S120 multi-axis servo drive (high-end motion control platform);
Product positioning: High-dynamic permanent magnet synchronous servo motor for machine tools and high-end automation, different from the economical 1FL6 V90 motor.
III. Main Functions and Core Features

1. High-precision closed-loop motion execution
   Built-in high-resolution encoder (single circle 23bit / multi-circle absolute encoder available), real-time feedback of rotor position, achieving micron-level precise positioning, supporting position, speed, and torque three-loop closed-loop control.
   The repeatability positioning error is extremely small, meeting the requirements of precision processing and high-speed return-to-position.
2. Ultra-high dynamic response characteristics
   Low inertia design of the rotor, fast acceleration and deceleration, the maximum rotational speed can reach 4500 rpm; output constant large torque at low speed, no speed jitter, suitable for high-frequency start-stop, multi-axis synchronous linkage scenarios.
3. Rich process motion control capabilities
   When paired with the S120 drive, it can achieve:
   Multi-axis electronic gears, electronic cams, synchronous following (shearing, printing synchronization);
   Tension control, master-slave coupling, interpolation motion (numerical control milling, engraving);
   STO safety torque shutdown, combined with the S7-1500F safety PLC to meet equipment safety standards.
4. Modular flexible configuration
   The same body can be selected with or without electromagnetic brake;
   Optical shaft / flat key / spline output shaft;
   Single circle / multi-circle absolute encoder;
   IP64/IP65 protection level, suitable for machine tool cutting fluid, dust environment.
   IV. Typical Application Scenarios
   CNC machine tools: machining centers, lathes, grinders, engraving machines feed spindles;
   High-end automation lines: lithium battery equipment, 3C precision assembly, soldering machines, inspection equipment;
   Printing / packaging machinery: high-speed cutting, synchronous offset printing, die-cutting station;
   Robots and mechanical hands: small joint robots, gantry mechanical hands;
   Testing equipment: dynamic durability test bench, precision positioning platform.
