I. Basic Model Classification
Brand: Siemens SIEMENS
Series: 1FK7 Compact Synchronous Servo Motor (SIMOTICS S-1FK7), compatible with SINAMICS S120 / V90 / 611U servo drive systems, widely used in machine tools, automated production lines, robotic arms, packaging equipment
Order Number: 1FK7032‑2AK71‑1CH1
Model Segmentation Explanation
1FK7032: Frame Specification
Frame size IEC 32, small volume compact motor
2AK71: Encoder + Brake + Cooling Configuration
2 = 2-pole permanent magnet synchronous
A = Absolute Value Encoder EnDat 2.1 single-turn absolute value (can store position without power-off, no need to return to zero)
K = Built-in built-in holding brake (power-off braking)
71 = Voltage Adaptation S120 servo, winding specification
1CH1: Output Shaft / Flange, Protection, Connector Structure
Optical Shaft (no keyway), standard flange, aviation plug side-out wiring, protection grade IP64

Key Electrical & Mechanical Parameters
Rated Speed: 6000 r/min
Rated Torque: 0.63 N·m
Stall Torque: 0.8 N·m
Rated Power: Approximately 200W (0.2kW)
Rated Current: 1.4 A
Power Supply: Powered by S120 servo drive
Encoder: EnDat2.1 single-turn absolute value encoder, supports high-precision position feedback
Brake: Built-in electromagnetic brake, power-off locking shaft, prevents shaft sliding, necessary for vertical shaft scenarios
Shaft Type: Smooth Shaft (no flat key)
Protection Grade: IP64 (motor body dust-proof, splash-proof water-proof)
Cooling Method: Natural Cooling (self-cooling, no fan required)
Operating Temperature Range: 0 ~ +40℃ (continuous operation)
Installation: Standard Flange Installation

Compatible Drives
Preferred: SINAMICS S120 servo drive system (CU320‑2 control unit)
Compatible with older models: 611U servo drive
Note: This EnDat absolute value encoder cannot be directly used with ordinary V90 pulse version drive, it requires a corresponding drive model that supports EnDat
