Applicable Industries: CNC machine tools, robotics, printing & packaging, semiconductor wafer handling, textile machinery, wind turbine pitch control, material handling systems

Installation Requirements:

  • Mount using M58 × 1 threaded mounting hole (rear flange)
  • Ensure shaft coupling alignment within 0.05 mm TIR
  • Use shielded twisted-pair cable for CAN connection (120 Ω termination at both ends)
  • Ground the encoder housing to < 1 Ω

Precautions:

  • Do not exceed 8000 RPM mechanical speed
  • Do not apply axial loads exceeding 10 N on the shaft
  • Ensure CAN bus termination (120 Ω) is installed at both ends of the network
