Key Functions（核心功能）

• Multi-Signal Integration:
  Simultaneously processes two types of critical signals:

• Digital Signals: Receives external logic commands (e.g., start/stop, forward/reverse) and sends digital status signals (e.g., inverter ready, fault alarm) to upper-level systems.

• Analog Signals: Converts standard 4-20mA current signals or 0-10V voltage signals (from sensors/PLCs) into inverter-compatible control signals (for speed/torque adjustment) and feeds back inverter operating parameters (e.g., output current, motor speed) as analog signals.

• Basic Communication Support:
  Enables basic data exchange with upper control systems via standard industrial protocols (e.g., Modbus RTU), facilitating remote parameter configuration and real-time monitoring of inverter status.

• Fault Diagnosis & Protection:
  Monitors key signal lines and internal board status; if abnormal signals (e.g., short circuits, signal loss) are detected, it triggers a fault alert and transmits error codes to the inverter’s main control unit, preventing damage to the drive system.

• Signal Stabilization:
  Built-in signal filtering and anti-interference circuits to reduce electromagnetic interference (EMI) and voltage fluctuations in industrial environments, ensuring signal accuracy (linearity error <0.2%) and stable inverter operation.

Compatibility（兼容性）

• Target Equipment: Exclusively designed for ABB ACS series mid-to-high power inverters, including but not limited to ACS800 heavy-duty models and ACS880 multi-drive systems.

• Incompatibility: Not suitable for low-power ABB inverter models (e.g., ACS150) or non-ABB industrial control equipment (e.g., Siemens, 施耐德 inverters).
