Product Overview

In modern industrial automation systems, reliable motor speed control is essential for maintaining production efficiency, machine stability, and consistent process performance. The Schneider ATV310HU55N4E is an Easy Altivar 310 Variable Speed Drive (VSD) designed to control compatible three-phase asynchronous motors in industrial machine applications.

The ATV310HU55N4E is a 5.5 kW Heavy Duty variable speed drive designed for three-phase power supplies from 380 to 460 VAC. It provides adjustable-frequency motor control, allowing compatible motors to operate at different speeds according to the requirements of the machine or production process.

For Normal Duty applications, the ATV310HU55N4E can support a motor rating of up to 7.5 kW / 10 HP, while its Heavy Duty rating is 5.5 kW / 7.5 HP. This distinction allows the drive to be selected according to the actual load characteristics and overload requirements of the application.

The main function of the ATV310HU55N4E is to regulate the frequency and voltage supplied to an AC motor. Instead of operating the motor continuously at a fixed speed, the drive can provide controlled acceleration, deceleration, starting, stopping, and variable-speed operation.

The specified dimensions of the ATV310HU55N4E are 184 × 140 × 151 mm, with an approximate product weight of 1.8 kg. Its compact form factor makes it suitable for industrial control cabinets and machine panels where installation space is important.

The ATV310HU55N4E supports U/F control and sensorless flux vector control, providing flexibility for different motor-control requirements. It also supports Modbus communication through a 2-wire RS-485 interface with an RJ45 connector, allowing the drive to be integrated with compatible PLCs and industrial automation systems.

The ATV310HU55N4E is suitable for a variety of applications, including material handling, packaging machines, textile equipment, machine tools, printing machines, woodworking machinery, ceramic machinery, conveyors, and other industrial equipment.

For OEM manufacturers, system integrators, automation engineers, and maintenance teams, the ATV310HU55N4E provides a compact and versatile solution for variable-speed motor control.

Technical Specifications

Function and Working Principle

The ATV310HU55N4E converts incoming three-phase AC power into a controlled variable-frequency output for a compatible asynchronous motor.

The basic power-conversion process can be represented as:

Three-Phase AC Input → Rectifier → DC Link → Inverter → Variable-Frequency AC Output → Motor

The drive receives the incoming AC supply and processes it through its power electronics. The inverter stage then generates a controlled three-phase output with adjustable frequency and voltage.

Motor speed is closely related to the frequency of the electrical supply. By changing the output frequency, the ATV310HU55N4E can regulate the motor speed according to machine requirements.

The drive can provide:

• Variable motor speed
• Controlled acceleration
• Controlled deceleration
• Smooth motor starting
• Controlled stopping
• Adjustable output frequency
• Motor thermal protection
• Overcurrent protection
• Overvoltage protection
• Undervoltage protection
• Overheating protection
• Fault monitoring
• Communication with PLC systems

The ATV310HU55N4E supports U/F control and sensorless flux vector control.

U/F control provides a straightforward solution for general-purpose applications where conventional frequency-based motor control is sufficient.

Sensorless flux vector control provides more advanced motor regulation and can improve torque and speed behavior without requiring a physical encoder or external motor-speed feedback device.

The drive supports an output frequency range of approximately 0.5 to 400 Hz, providing flexibility for applications with different speed requirements.

Acceleration and deceleration ramps can also be configured according to the machine’s mechanical characteristics.

For example, on a conveyor system, the PLC can issue a start command to the ATV310HU55N4E. The drive can then increase the output frequency progressively according to the configured acceleration time.

When the operating speed needs to change, the controller can provide a new reference. The drive adjusts its output frequency accordingly.

During shutdown, the drive can reduce the motor frequency according to the programmed deceleration ramp.

The drive also incorporates protection functions designed to detect abnormal operating conditions, including:

• Line supply overvoltage
• Line supply undervoltage
• Output overcurrent
• Drive overheating
• Short circuit between motor phases
• Output phase-to-ground faults
• Three-phase input phase loss
• Motor thermal overload

These functions help protect the drive, motor, and associated machine equipment during normal industrial operation.

Role in Industrial Control Systems

The ATV310HU55N4E acts as the motor-control interface between an automation controller and a compatible three-phase asynchronous motor.

A typical industrial system may include:

• Schneider Modicon PLC
• Schneider HMI
• ATV310HU55N4E Variable Speed Drive
• Three-phase asynchronous motor
• Motor circuit breaker
• Magnetic contactor
• Proximity sensors
• Pressure sensors
• Temperature sensors
• Remote I/O modules
• Modbus RTU network
• RS-485 communication equipment
• Industrial communication gateway
• SCADA system

Field sensors provide process information to the PLC.

The PLC evaluates this information and determines the required operating condition.

The ATV310HU55N4E receives the appropriate speed reference or control command and regulates the connected motor.

When Modbus RTU communication is used, the drive can exchange operating information with compatible automation controllers.

Depending on the configuration, the PLC or HMI can monitor:

• Motor frequency
• Speed reference
• Drive operating status
• Fault status
• Alarm information
• Communication status
• Selected drive parameters

This allows the ATV310HU55N4E to function as part of an integrated automation architecture rather than operating as an isolated motor controller.
