Schneider ATV630D45N4 Variable Speed Drive

The Schneider Electric ATV630D45N4 is a high-performance variable speed drive (VSD) from the Altivar Process ATV600 range. Designed specifically for industrial processes and utilities, it excels in fluid management (pumps, fans, and compressors) by offering embedded energy management and asset monitoring functions.

Technical Specifications

Communication & Control

Key Features

• Embedded Intelligence: Features "Stop-and-Go" functions to reduce energy consumption during standby and an integrated "Pump Curve" tool to optimize hydraulic performance.

• Asset Management: Includes an embedded web server and dynamic QR codes for instant access to diagnostics and maintenance data via a smartphone.

• Safety Integration: Comes standard with Safe Torque Off (STO) SIL3/PLe, reducing the need for external safety contactors while meeting global safety standards.

• Harmonic Mitigation: Built-in DC choke limits total harmonic distortion ($THDi$) to less than 48% without additional filters.

Installation Guidelines

• Cooling Requirements: The unit dissipates approximately 990 W of heat at full load. Ensure adequate ventilation in the enclosure and maintain the minimum clearance distances (top/bottom/sides) specified in the mounting manual.

• Wiring: Use shielded motor cables to comply with EMC requirements. Ensure the ground connection (PE) is secure and follows a star-point grounding scheme to minimize electrical noise.

• Mounting: The ATV630D45N4 is designed for wall mounting or enclosure mounting. It must be installed vertically ($10^\circ$ tolerance) to ensure proper heat convection.

• Input Protection: Use high-speed fuses or a circuit breaker (e.g., Schneider TeSys GV4) rated for the drive's input current to protect against short circuits.

Frequently Asked Questions (FAQs)

What is the difference between "Normal Duty" and "Heavy Duty"?

Normal Duty (45 kW) is for applications with low overload requirements (up to 110% for 60s), like centrifugal pumps. Heavy Duty (37 kW) is for high-torque applications (up to 150% for 60s), like conveyors or positive displacement pumps.

Can I control this drive via a PLC over Ethernet?

Yes. The dual Ethernet/IP and Modbus TCP ports allow for seamless integration with Schneider Modicon PLCs or other industrial controllers like Rockwell or Siemens.

What is the "Stop-and-Go" function?

This function automatically puts the drive into a low-power state when the motor is not required to run, reducing internal consumption by up to 60% during idle periods.

Is the Graphic Display Terminal included?

Yes, standard ATV630 models include a removable plain text graphic display terminal that supports multi-language diagnostics and parameter backup.
