• Integrated Class A EMC filters for conducted and radiated interference suppression.
• Supports multiple control profiles including V/f (2-point, 5-point, or quadratic) and flux vector control.
• Built-in Modbus and CANopen communication protocols with expansion capabilities for Profibus DP, DeviceNet, and Ethernet/IP.
• Comprehensive protection suite including thermal monitoring, surge suppression, and phase-to-phase short circuit protection.
• Modular architecture allowing for easy integration of I/O expansion cards.

Applications

The ATV61HD37N4 is specifically optimized for applications requiring precise torque control and energy management, including centrifugal pumps, industrial fans, compressors, and HVAC air handling units.

Technical Specifications

Installation Guidelines

• Ensure adequate ventilation; the drive utilizes forced convection cooling and requires clearance for airflow.
• Mount the drive vertically on a flat, vibration-free surface.
• Use shielded cables for motor connections to comply with EMC requirements and minimize noise.
• Verify that the line voltage matches the drive input rating (380-480 VAC) before applying power.
• Always disconnect power and wait for the internal capacitors to discharge (refer to the status LED) before performing maintenance or wiring changes.
• Ensure proper grounding of the drive chassis to the main plant earth bus to prevent electrical hazards.

Compliance and Certifications

The ATV61HD37N4 meets international standards including CE, UL, CSA, C-Tick, GOST, and NOM.
