Optimize Industrial Process Control with the Schneider ATV930D37N4

For demanding industrial applications requiring precise motor control and energy efficiency, the Schneider ATV930D37N4 variable speed drive delivers robust performance. Part of the Altivar Process ATV900 series, this 37 kW drive is engineered for asynchronous and synchronous motors, integrating a braking chopper for enhanced dynamic control. Its IP21 enclosure and wall-mount design simplify installation in controlled environments.

Technical Specifications Breakdown

Key parameters for the ATV930D37N4 are listed below for quick reference:

Industry Applications and Cost-Benefit

Its integrated EMC filter and compliance with IEC 61800-3 reduce installation costs by eliminating external filtering. The built-in PID regulator optimizes pump and fan control, lowering energy consumption. With heavy-duty rating of 30 kW, it handles peak loads without oversizing, improving operational ROI.

Installation and Setup Guidance

Mount the drive vertically within ±10 degrees. Use the provided screw terminals for line and motor connections: 35...50 mm² (AWG 3...AWG 1). For control wiring, use 0.5...1.5 mm² (AWG 20...AWG 16). Ensure ambient temperature stays between -15 °C and 50 °C without derating. Above 50 °C, apply derating up to 60 °C.

Maintenance and Reliability

Routine inspection of cooling air intake and filter cleanliness is recommended. The drive operates reliably in environments classified as 3C3 (chemical) and 3S3 (dust) per IEC 60721-3-3. Ambient humidity should remain 5...95 % without condensation. For storage, keep temperature between -40 °C and 70 °C.

Compatibility and Integration

The ATV930D37N4 supports Modbus TCP, Modbus serial, and EtherNet/IP natively. Optional communication modules include Profibus DP V1, PROFINET, DeviceNet, EtherCAT, CANopen, and Ethernet Powerlink. It also accepts digital and analog I/O extension modules, encoder interfaces, and relay extensions. Integrated safety functions include Safe Torque Off (STO), Safe Stop 1 (SS1), Safely Limited Speed (SLS), and Safe Brake Management (SBC/SBT).

Selection Guide and Purchasing Advice

When selecting a drive, match the motor power and duty cycle to the application. For normal duty, the drive delivers 37 kW; for heavy duty, 30 kW. Verify lifecycle status with AutoDCSTech before ordering. Our team can help confirm compatibility with your existing system.
