Product Overview

Reliable motor speed control is an important part of industrial automation, particularly for machines that require adjustable operating speeds, controlled acceleration, and stable performance under changing production conditions. The Schneider ATV310HU30N4E is an Easy Altivar 310 Variable Speed Drive (VSD) designed to regulate compatible three-phase asynchronous motors in industrial machine applications.

The ATV310HU30N4E is a compact variable speed drive designed for applications requiring approximately 3 kW motor power and controlled variable-frequency operation. It is intended for use with three-phase 380–460 VAC power supplies, making it suitable for common industrial electrical systems.

The main purpose of the ATV310HU30N4E is to control the speed and operating characteristics of an AC motor by regulating the frequency and voltage supplied to the motor. Instead of operating a motor continuously at a fixed speed, the drive allows the motor to accelerate, decelerate, and operate at different speeds according to the requirements of the machine.

The specified dimensions of the ATV310HU30N4E are 184 × 140 × 151 mm, while the approximate product weight is 1.8 kg. Its compact design provides a practical solution for machine control cabinets where available installation space is limited.

The ATV310HU30N4E supports U/F control and sensorless vector control, allowing engineers to select a suitable motor-control method according to application requirements. The drive can also communicate with compatible industrial automation equipment using Modbus RTU over RS-485.

For OEM machine builders, system integrators, and industrial maintenance teams, the ATV310HU30N4E provides a practical method of adding adjustable-speed motor control to conveyors, pumps, fans, packaging equipment, material-handling systems, and other industrial machinery.

Technical Specifications

Function and Working Principle

The ATV310HU30N4E converts incoming electrical power into a controlled variable-frequency output for a compatible three-phase asynchronous motor.

The basic power-conversion sequence can be represented as:

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

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

Motor speed is closely related to the frequency of the supplied electrical power. By changing the output frequency, the ATV310HU30N4E can adjust motor speed according to the machine’s operating requirements.

The drive can provide:

• Variable motor speed
• Controlled acceleration
• Controlled deceleration
• Smooth motor starting
• Controlled stopping
• Adjustable frequency
• Motor protection
• Fault monitoring
• Alarm monitoring
• Communication with PLC systems

The ATV310HU30N4E supports two primary motor-control approaches: U/F control and sensorless vector control.

U/F control provides a straightforward solution for many general-purpose motor applications.

Sensorless vector control provides more advanced regulation of motor torque and speed without requiring a physical speed feedback device.

The drive also incorporates monitoring and protective functions designed to help identify abnormal electrical or operating conditions.

Depending on the application and configuration, these functions 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 an automated conveyor system, a PLC can provide a start command and speed reference to the ATV310HU30N4E. The drive gradually increases motor frequency according to the configured acceleration ramp.

If production requirements change, the PLC can provide a new speed reference. The drive then adjusts the motor operating frequency accordingly.

When the machine needs to stop, the drive can reduce the frequency according to the programmed deceleration ramp.

This provides smoother and more flexible operation than a traditional fixed-speed motor starter.

Role in Industrial Control Systems

The ATV310HU30N4E serves as the motor-control interface between an automation controller and a compatible three-phase asynchronous motor.

A typical automation system may contain:

• Schneider Modicon PLC
• Schneider HMI
• ATV310HU30N4E Variable Speed Drive
• Three-phase asynchronous motor
• Motor circuit breaker
• Magnetic contactor
• Proximity sensors
• Pressure sensors
• Temperature sensors
• Remote I/O modules
• Modbus communication network
• RS-485 communication equipment
• Industrial communication gateway
• SCADA system
• Emergency stop equipment

The PLC processes information from sensors and operator interfaces.

Based on this information, the PLC determines the required motor operating condition and sends appropriate commands to the variable speed drive.

The ATV310HU30N4E then converts these commands into controlled motor operation.

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

The automation system may monitor:

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

This architecture allows motor control to be integrated directly into the machine’s overall automation strategy.
