Working Principle:
The module utilizes high-speed ADC sampling and embedded PID algorithms to process real-time analog signals. It translates these signals into precise control commands via industrial Ethernet protocols, ensuring synchronized multi-axis operation.
Installation Requirements:
- Ensure RJ45 connectors are securely seated to prevent communication loss.
- Connect analog sensors correctly (positive to AI+, negative to AI-).
Usage Precautions:
- Configure static IP addresses via ABB DriveManager to avoid network conflicts.
- Use signal isolators if common-mode interference affects analog inputs.
