ABB BSM80C-275AFX Encoder Module  

1. Key Parameters

• Product Model: BSM80C-275AFX (standard identifier for ABB BSM C-series servo motor encoder modules)
• Core Function: Real-time feedback of motor position, speed, and rotation direction for closed-loop servo control
• Encoder Type: Incremental encoder (with commutation signal output for brushless motor commutation)
• Resolution: 2500 pulses per revolution (PPR) (base resolution; configurable for higher counts via servo drive interpolation)
• Commutation Support: Built-in commutation signals (UVW) – enables precise phase commutation for BSM C-series brushless AC servo motors
• Motor Compatibility: Exclusively for ABB BSM C-series servo motors (matched to motor frame size 80, rated power 0.92kW/1.2hp)
• Electrical Ratings:
  • Supply Voltage: 5V DC (±5% tolerance, regulated from servo drive)
  • Maximum Current Consumption: ≤50mA
  • Output Signal Type: Differential line driver (RS422 standard) – reduces electromagnetic interference (EMI) for long-distance signal transmission
• Signal Outputs:
  • Position Signals: A, /A, B, /B (quadrature differential signals for position/speed calculation)
  • Commutation Signals: U, /U, V, /V, W, /W (differential commutation signals for motor phase control)
  • Index Signal: Z, /Z (1 pulse per revolution, differential; for reference position calibration)
• Mechanical Specifications:
  • Mounting: Direct flange mounting (integrated with BSM80C-series motor shaft; no additional alignment required)
  • Shaft Interface: Matches BSM80C-series motor shaft (hollow shaft design, compatible with motor’s torque transmission)
  • Protection Class: IP54 (same as matched BSM C-series motor; dust-proof, splash-proof)
• Environmental Ratings:
  • Operating Temperature Range: -10℃~+60℃ (5℉~140℉)
  • Storage Temperature Range: -40℃~+85℃ (-40℉~185℉)
  • Vibration Resistance: 10~2000Hz, 10g acceleration (compliant with IEC 60068-2-6)
  • Shock Resistance: 50g acceleration (11ms duration, compliant with IEC 60068-2-27)
• Compliance Standards: IEC 61000-6-2 (EMC immunity), IEC 60034-1 (rotating electrical machines), UL 1004 (electrical safety)

2. Product Features

• High-Precision Feedback: 2500 PPR base resolution (with optional drive-based interpolation up to 1 million counts per revolution) enables sub-millimeter positioning accuracy – critical for precision applications like CNC machining and robotic assembly.
• Differential Signal Output: RS422 differential line driver technology minimizes EMI interference, ensuring stable signal transmission even in noisy industrial environments (e.g., near high-power motors, inverters).
• Integrated Commutation Signals: Built-in UVW commutation signals eliminate the need for external commutation sensors, simplifying motor-drive integration and reducing system complexity.
• Seamless Motor Matching: Exclusively designed for ABB BSM80C-series servo motors (0.92kW/1.2hp, 4-pole), ensuring perfect mechanical and electrical compatibility – avoids alignment errors or signal mismatches common with generic encoders.
• Rugged IP54 Protection: Dust-proof and splash-proof design matches the motor’s environmental resilience, enabling use in harsh manufacturing environments (e.g., machine shops, packaging lines with coolant splash).
• Reference Index Signal: Z-/Z differential index signal allows easy calibration of reference positions (e.g., machine home position), simplifying system setup and improving repeatability.

3. Application Fields

• CNC Machining: Provides position/speed feedback for CNC lathes, mills, and routers – ensuring precise toolpath control and high-quality part machining.
• Industrial Robotics: Enables accurate joint motion control for robotic arms (e.g., pick-and-place robots, assembly robots) – supporting smooth, repeatable movements in automotive and electronics manufacturing.
• Packaging Machinery: Controls servo motors in labeling machines, filling equipment, and flow wrappers – ensuring precise synchronization of packaging processes and reducing material waste.
• Printing Machinery: Regulates motor speed/position in digital printers and flexographic presses – maintaining consistent print registration and image quality.
• Semiconductor Equipment: Supports precision motion control in wafer handling robots and inspection tools – meeting the ultra-high accuracy requirements of semiconductor manufacturing.
• Material Handling: Controls servo motors in automated guided vehicles (AGVs) and linear actuators – ensuring precise positioning for load transport in warehouses and factories.

4. Precautions

• Motor Compatibility: Use exclusively with ABB BSM80C-series servo motors (0.92kW/1.2hp, frame size 80) – generic or mismatched motors will cause mechanical misalignment or electrical signal failure.
• Power Supply Stability: Ensure the 5V DC supply (from the servo drive) is regulated and free of voltage spikes – unstable power can corrupt position signals or damage the encoder’s internal circuitry.
• Wiring Best Practices: Use shielded twisted-pair cables for encoder signal wiring (minimum 24 AWG); ground the cable shield at the servo drive end (single-point grounding) to minimize EMI. Do not route encoder cables alongside high-voltage power cables (minimum 30cm spacing).
• Mechanical Installation: Do not disassemble the encoder or modify the mounting flange – improper handling can damage the internal optical components or disrupt alignment, leading to feedback errors.
• Environmental Limits: Do not operate beyond the -10℃~+60℃ temperature range or expose to direct coolant jets (IP54 is splash-proof, not submersion-proof). Use protective covers in environments with heavy dust or oil mist.
• Calibration & Testing: After installation, verify signal integrity via the servo drive’s diagnostic tools (e.g., check for missing pulses, commutation signal alignment). Recalibrate the reference index (home position) if the encoder is replaced – incorrect calibration will cause positioning errors
