  • Working Principle:
    • Operates as a closed-loop digital servo amplifier. The drive receives motion commands via fieldbus or analog/digital inputs, processes them through embedded PID control loops (current, velocity, position), and outputs precisely modulated PWM signals to the connected servo motor. Real-time feedback from the motor encoder or resolver is continuously compared against the command to minimize positioning error.
  • Installation Requirements:
    • Panel mounting in a ventilated control cabinet with adequate clearance for heat dissipation
    • Use shielded cables for all motor power, feedback, and fieldbus connections
    • Ensure proper grounding and equipotential bonding
    • Provide stable 24 VDC auxiliary power supply
  • Usage Notes:
    • The “FN3” suffix indicates a specific feedback/network interface configuration — verify compatibility with the connected motor and controller before commissioning
    • Verify motor nameplate parameters are correctly configured in the drive using the Windows-based GUI setup software
    • This is a legacy product; consult Kollmorgen for AKD-series migration options
