Product Overview

Efficient motor speed control is an important part of modern industrial automation, particularly for machines that require adjustable operating speeds, controlled acceleration, and reliable motor protection. The Schneider ATV310HU22N4E is an Easy Altivar 310 Variable Speed Drive (VSD) designed to control compatible three-phase asynchronous motors in industrial machine applications.

The ATV310HU22N4E is a compact variable speed drive designed for motor applications where reliable frequency conversion and straightforward machine integration are required. It provides adjustable motor speed by controlling the frequency and voltage supplied to the connected AC motor.

Unlike a conventional fixed-speed motor starter, a variable speed drive allows the motor to operate at different speeds according to the requirements of the production process. This makes the ATV310HU22N4E useful for conveyors, pumps, fans, material-handling equipment, packaging machinery, and other general-purpose industrial machines.

The specified dimensions of the ATV310HU22N4E are 143 × 105 × 151 mm, and its approximate weight is 1.1 kg. Its compact design allows it to be installed in space-constrained industrial control cabinets and machine panels.

The ATV310HU22N4E supports multiple motor-control functions, including U/F control and sensorless vector control. These control methods allow the drive to be configured for different motor and load characteristics.

The drive can also communicate with industrial automation equipment through Modbus RTU over RS-485, making it suitable for PLC-based control systems.

For OEM machine builders, system integrators, and industrial maintenance teams, the ATV310HU22N4E provides a practical solution for integrating adjustable-speed motor control into compact automation systems.

Technical Specifications

Function and Working Principle

The primary function of the ATV310HU22N4E is to regulate the operating speed of a compatible three-phase asynchronous motor.

A standard AC motor connected directly to a fixed-frequency supply generally operates at a relatively constant speed. The variable speed drive introduces electronic power conversion between the electrical supply and motor, allowing the output frequency and voltage to be controlled.

The basic operating sequence can be represented as:

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

The drive processes the incoming AC power and generates a controlled three-phase output.

By adjusting the output frequency, the ATV310HU22N4E can change motor speed according to the required machine operating condition.

The drive can provide:

• Adjustable motor speed
• Controlled acceleration
• Controlled deceleration
• Smooth motor starting
• Controlled stopping
• Adjustable frequency
• Motor protection
• Fault monitoring
• Alarm monitoring
• PLC communication

The ATV310HU22N4E supports U/F control and sensorless vector control.

U/F control is appropriate for many basic motor applications where straightforward frequency-based control is sufficient.

Sensorless vector control provides a more advanced control method that can improve motor performance and torque characteristics without requiring a physical speed feedback sensor.

The drive also includes protective functions designed to help detect abnormal operating conditions.

These can include:

• Motor overload protection
• Overcurrent protection
• Overvoltage protection
• Undervoltage protection
• Motor thermal protection
• Drive thermal protection
• Phase monitoring
• Fault detection
• Alarm monitoring

For example, in a conveyor application, the PLC can send a start command and speed reference to the ATV310HU22N4E.

The drive increases the output frequency according to the configured acceleration ramp. During operation, the PLC can adjust the speed reference when production requirements change.

When the machine stops, the drive can reduce the output frequency according to the configured deceleration ramp.

This provides smoother and more flexible motor control than direct fixed-speed operation.

Role in Industrial Control Systems

The ATV310HU22N4E acts as a motor-control interface between the automation controller and the connected three-phase motor.

A typical control system may include:

• Schneider Modicon PLC
• Schneider HMI
• ATV310HU22N4E Variable Speed Drive
• Three-phase asynchronous motor

• Magnetic contactor
• Proximity sensors
• Pressure sensors
• Temperature sensors
• Remote I/O modules
• Modbus communication network

The PLC receives process information from sensors and determines the required motor operating condition.

The ATV310HU22N4E receives the appropriate control command and regulates the motor.

When Modbus RTU is used, the drive can exchange information with compatible industrial controllers.

Depending on the system configuration, the controller can monitor:

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

This allows the drive to operate as an integrated component of the machine automation system.
