The Schneider Electric ATV320D18N4C (

) is a high-performance machine drive designed to handle demanding industrial loads with advanced intelligence and safety.

1. Advanced Integrated Safety (SIL3/PLe)

The most critical feature of the ATV320 range is that it eliminates the need for external safety relays by including 5 built-in safety functions:

• STO (Safe Torque Off): Standard protection to prevent accidental motor restarts.
• SS1 (Safe Stop 1) & SLS (Safely-Limited Speed): Manages safe machine deceleration and speed limits.
• SMS & GDL: Features for maximum speed monitoring and guard door interlocking.
• Compliance: Certified to the highest industrial levels (SIL3 and PLe), significantly reducing wiring complexity and hardware costs.

2. "Altivar Logic" (Built-in PLC)

• Onboard Automation: The drive features programmable logic capability. You can program simple automation sequences and logic directly into the drive (e.g., managing sensor inputs to trigger specific speeds) without needing a separate small PLC.

3. Precision Motor Control

• Universal Motor Support: It can drive both standard asynchronous (induction) motors and high-efficiency synchronous (Permanent Magnet) motors.
• Superior Torque: Uses Sensorless Flux Vector Control to maintain extremely high torque even at very low speedscritical for starting heavy conveyors, mixers, or crushers.

4. Ruggedized for Harsh Environments

• Extreme Protection: The circuit boards are 3C3 and 3S2 coated, making the drive highly resistant to humidity, chemical gases, and saltideal for textile, chemical, or woodworking plants.
• High Temp Tolerance: Operates reliably in ambient temperatures up to 
  
  
   without power loss, and up to 
  
  
   with minor adjustments.
• Isolated Airflow: The cooling path is separated from the electronics to prevent dust or metallic particles from settling on the internal boards.

5. Seamless Connectivity

• Standard Ports: Built-in CANopen and Modbus RTU.
• Expansion Ready: Supports "plug-in" communication modules for Profinet, EtherNet/IP, EtherCAT, and Profibus DP for easy integration into any factory network.
