Schneider Electric ATV630D55N4 Overview

The Schneider Electric ATV630D55N4 is a variable-speed drive belonging to the Altivar Process ATV600 range. It is designed for process and utility applications, specifically for controlling asynchronous and synchronous motors. With a power rating of 55 kW or 75 HP, it operates on a supply voltage range of 380 to 480 VAC. The drive has an IP21 degree of protection, which ensures its resistance to solid objects and the ingress of moisture. These products are manufactured in France and are designed for Material handling, packaging, and textile machines usage. They come with a 2-year warranty from MRO Electric. We also carry AC Drives from other manufacturers such as Modicon and ABB.


As a standard version of the ATV630, this variable-speed drive offers advanced motor control capabilities and is suitable for a wide range of industrial applications. Its wall-mounting mode allows for easy installation in various settings, while forced convection cooling ensures efficient heat dissipation and optimal performance.

The drive is capable of controlling both asynchronous and synchronous motors. In constant torque standard mode, it provides precise control for applications that require a consistent torque output. It also supports variable torque standard mode and optimized torque mode, allowing for efficient operation across a wide range of load conditions. Additionally, it offers support for permanent magnet motors, enabling high-performance control for applications utilizing this motor type.


The ATV630D55N4 features an integrated EMC filter, complying with EN/IEC 61800-3 category C3 standards, which reduces electromagnetic interference and enhances the overall performance and reliability of the drive. The drive has a supply frequency range of 50 to 60 Hz, with a tolerance of 5%. It operates on a three-phase power system and accepts a rated supply voltage between 380 and 480 V, with a tolerance of 15 to 10%.

With an output frequency range of 0.0001 to 0.5 kHz, the drive allows for fine control of motor speed. The speed drive output frequency spans from 0.1 to 599 Hz, providing flexibility in motor speed adjustment. The ATV630D55N4 operates with a nominal switching frequency of 2.5 kHz, but it can be adjusted within a range of 2 to 8 kHz, with the option of derating beyond 2.5 kHz.


In terms of safety, the drive features a Safe Torque Off (STO) function certified for SIL 3, ensuring the motor's safe shutdown during critical situations. It also offers various protection functions, including protection against motor phase break, overheating, short-circuit, overspeed, overvoltages on the DC bus, overload of output voltage, line supply overvoltage, line supply phase loss, and more.

The drive provides multiple communication options, including Modbus TCP, Modbus serial, and Ethernet. It supports various communication modules such as Profibus DP V1, Profinet, DeviceNet, Modbus TCP/EtherNet/IP, and CANopen. These modules enable seamless integration into different automation systems, providing flexibility and ease of use.

The ATV630D55N4 includes analog and discrete inputs and outputs for connection with external devices. It offers three analog inputs that can be configured for voltage or current signals. Additionally, there are eight programmable discrete inputs and three configurable relay outputs for versatile control and monitoring capabilities.


The physical interface of the drive includes removable screw terminals for easy electrical connections. It provides adequate protection against temporary current boosts and supports motor slip compensation to ensure optimal motor performance under varying load conditions. The drive also offers adjustable acceleration and deceleration ramps, allowing for precise control of motor speed changes.

Measuring 290 mm in width, 922 mm in height, and 323 mm in depth, the ATV630D55N4 weighs 56.5 kg. It is designed for utility applications and is suitable for a range of industries, including HVAC, food and beverage processing, mining, oil and gas, and water and wastewater treatment.

In summary, the SchneiderElectric ATV630D55N4 is a versatile variable-speed drive designed for process and utility applications. With its advanced motor control capabilities, integrated EMC filter, and comprehensive protection features, it provides reliable and efficient operation for a wide range of industrial applications. The drive's flexibility, communication options, and ease of installation make it a reliable choice for controlling both asynchronous and synchronous motors.
