- Working Principle:
- Digital closed-loop servo control with PID regulation. The drive receives motion commands, processes them through embedded control loops, and outputs modulated PWM signals to the motor. Feedback from the motor’s encoder or resolver is continuously compared against the command to minimize error. The macro programming environment enables standalone motion logic execution.
- Installation Requirements:
- Mount in a well-ventilated control cabinet
- Use shielded cables for all motor, feedback, and fieldbus connections
- Ensure proper grounding and equipotential bonding
- Maintain minimum clearance for thermal management
- Usage Notes:
- The “FN3” suffix indicates a different feedback/network interface configuration compared to the “-FN2” variant — verify exact interface pinout and protocol compatibility with the connected motor and controller
- This is a legacy product; consult Kollmorgen for AKD-series migration options
