Product Introduction
When aging variable speed drives cause production inefficiencies or safety concerns, upgrading to the Schneider ATV930D37N4 provides a reliable solution. Part of the Altivar Process ATV900 series, this industrial automation module is a wall-mountable, three-phase variable speed drive designed for asynchronous and synchronous motors. With a standard variant that includes a braking chopper and IP21 protection, the Schneider ATV930D37N4 delivers 37.0 kW (normal duty) or 30.0 kW (heavy duty) of motor power, supporting 380-480 V supply voltage. Integrated safety functions such as Safe Torque Off (STO), Safely Limited Speed (SLS), and Safe Stop 1 (SS1) make it an essential upgrade for process industries requiring functional safety.

Industrial Applications
The Schneider ATV930D37N4 excels in process industries such as water/wastewater, HVAC, material handling, and pumping. For example, in a constant torque application (e.g., conveyor), the drive's variable torque and constant torque control profiles ensure smooth operation up to 599 Hz. The integrated Modbus TCP and EtherNet/IP enable easy integration into existing automation networks, reducing commissioning time. When replacing older fixed-speed starters, this drive's built-in safety functions (STO, SLS) help meet modern safety standards without additional hardware.
Installation & Setup Guide
Mount the Schneider ATV930D37N4 vertically on a wall with the recommended clearance for airflow. Electrical connections use screw terminals: control wiring (0.5...1.5 mm²), DC bus and line/motor wiring (25...50 mm²). Ensure the supply voltage is within 380-480 V (tolerance -15...10 %). For communication, use the RJ45 ports for Modbus TCP/EtherNet/IP and the 2-wire RS485 for Modbus serial. The drive's sampling durations (2 ms for digital inputs, 1 ms for analog) support high-speed control loops. Verify proper grounding and overvoltage category III compliance as per the datasheet.
Maintenance & Reliability
Regular inspections of cooling fans and air filters are essential, especially in environments with high dust or humidity (class 3S3 pollution). The Schneider ATV930D37N4 operates from -15°C to 50°C without derating (up to 60°C with derating). The drive's integrated protections (overheating, overcurrent, short-circuit, etc.) reduce unplanned downtime. With a shock resistance of 15 gn and vibration resistance per IEC 60068-2-6, this drive is built for harsh industrial conditions.
Selection Guide & Purchasing Advice
Before purchasing, verify that the motor power (37 kW normal duty) matches your load requirements and that the network voltage is within the 380-480 V range. If you need additional communication options (e.g., Profibus DP, PROFINET), the option card slots (Slot A/B/C) accept various modules.
