Core Functions & High-End Features
Performance Motor Control: Feeds both 3-phase synchronous (permanent magnet, reluctance) and asynchronous motors with high-precision torque and speed regulation.
Dual-Rating Strategy: Rated for 55 kW (75 hp) for normal duty (up to 120% overload) and 45 kW (60 hp) for heavy-duty applications (up to 150% overload).
Industrial Intelligence: Features an embedded web server and real-time energy dashboard for fast troubleshooting, power measurement, and preventive maintenance.
Deep Connectivity: Standard dual-port EtherNet/IP and Modbus TCP allow for deep integration into automation architectures.
Safety & Reliability: Features standard Safe Torque Off (STO) and Safe Stop 1 (SS1) (SIL 3) for enhanced process security.
The Schneider Electric ATV930D55N4Z is an advanced "Industrial Process Drive" for 55 kW (75 hp) motors. It is specifically built for heavy industrial processes that require extreme torque precision, high-level safety, and "smart" data monitoring.
1. High-Performance Motor Control
Total Motor Flexibility: It drives nearly any 3-phase motor, including Standard Induction, Permanent Magnet (PM), and Synchronous Reluctance (SynRM) motors.
Dynamic Torque Control: Provides 100% torque even at zero speed, which is critical for holding heavy loads in gantry cranes, hoists, or massive mixers.
Master/Slave Load Sharing: Allows two drives to work together on the same mechanical system (like a long conveyor belt) to perfectly balance the motor torque and prevent mechanical stress.
2. Embedded Intelligence & IIoT Ready
Smart Sensorless Monitoring: The drive acts as a sensor, detecting pump cavitation, clogged filters, or leaking pipes simply by analyzing the motors electrical behavior.
Integrated Web Server: You can view real-time Energy Dashboards, performance graphs, and historical logs via a standard web browser over Ethernet.
Asset Management: It monitors its own health and motor temperature, alerting you before a failure occurs to avoid unplanned downtime.
3. Advanced Safety & Braking
Safe Torque Off (STO): Features high-level hardware safety (SIL3/PLe) that instantly removes motor torque for safe manual intervention without cutting the main power.
Built-in Braking Transistor: Includes an internal braking unit to handle energy "pushed back" by a stopping motor, allowing for very fast, controlled stops of high-inertia loads.
4. Connectivity & System Uptime
Dual Ethernet Ports: Supports EtherNet/IP and Modbus TCP out of the box. The dual-port design allows for "Ring" wiring, ensuring the drive stays connected even if one network cable fails.
Process Specific Logic: Includes specialized functions for Pipe Fill (to prevent water hammer), Dry Run protection, and Anti-clogging for pumps.
5. Ruggedness
3C3 Conformal Coating: Circuit boards are treated to resist corrosion from moisture and chemical gases, making it ideal for harsh industrial environments like mining, chemical plants, or wastewater facilities.
