is a high-performance 18.5 kW (25 hp) variable speed drive designed for complex industrial processes. This "Z" variant is specifically engineered for cabinet integration and typically comes without a keypad to allow for compact mounting in electrical panels.
Physical Dimensions & Weight
These specifications are key for panel layout and mechanical support:
Net Weight: 30.0 lbs (13.6 kg).
Height: 18.9 in (480 mm).
Width: 7.7 in (195 mm).
Depth (Length): 9.25 in (235 mm).
Core Functions & High-End Features
Power Capability: Supports up to 18.5 kW (25 hp) for normal duty (120% overload) and 15.0 kW (20 hp) for heavy-duty applications (150% overload).
High-Performance Motor Control: Feeds both 3-phase synchronous (permanent magnet, reluctance) and asynchronous motors with high precision.
Industrial Intelligence: Features an integrated Energy Dashboard for power measurement and a built-in web server for diagnostics and data logging.
Connectivity: Standard dual-port EtherNet/IP and Modbus TCP allow for deep integration into automation architectures.
Safety & Protection: Equipped with Safe Torque Off (STO) and Safe Stop 1 (SS1) (SIL 3) for process security.
The Schneider Electric ATV930D18N4Z is an advanced "Industrial Process Drive" for 18.5 kW (25 hp) motors. It focuses on maximizing process uptime and asset protection through high-end motor control and data intelligence.
1. High-Performance Motor Control
Total Motor Flexibility: Controls Standard Induction, Permanent Magnet (PM), and Synchronous Reluctance (SynRM) motors.
Master/Slave Load Sharing: Includes logic to balance the load between two drives/motors working on the same mechanical system (e.g., a long conveyor belt or large gantry).
Full Torque at Zero Speed: Essential for "holding" heavy loads in mixers or hoists without mechanical slipping.
2. Embedded Intelligence & IIoT Ready
Sensorless Process Monitoring: Detects pump cavitation, clogged filters, or leaking pipes purely by analyzing electrical changesno external sensors needed.
Embedded Web Server: Access real-time Energy Dashboards, performance graphs, and historical logs via a standard web browser over Ethernet.
Predictive Maintenance: Tracks internal component wear and motor health, alerting you before a failure occurs to avoid unplanned downtime.
3. Advanced Safety & Braking
Safe Torque Off (STO): Built-in hardware safety (SIL3/PLe) that instantly removes torque from the motor for safe human intervention.
Built-in Braking Transistor: Includes an internal unit to handle energy "pushed back" by the 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, so the drive stays online even if one network cable fails.
Fluid Management Logic: Specialized functions for Pipe Fill (prevents water hammer), Dry Run protection, and Anti-clogging for pumps.
5. Durability
3C3 Conformal Coating: Circuit boards are treated to resist corrosion from moisture and chemical gases, making it ideal for harsh industrial environments like wastewater or chemical plants.
