Product Overview

Reliable motor control is a key requirement in industrial automation, particularly for machinery that operates continuously or under changing load conditions. The Schneider ATV310HD22N4A is an Easy Altivar 310 Variable Speed Drive (VSD) designed to provide adjustable speed and controlled operation for compatible three-phase asynchronous motors.

The ATV310HD22N4A is a higher-power model in the Easy Altivar 310 family and is designed for industrial machine applications requiring dependable motor speed regulation. It is suitable for 22 kW Heavy Duty motor applications and can provide variable-frequency control for compatible three-phase motors supplied from a 380–460 VAC three-phase power system.

The primary purpose of the ATV310HD22N4A is to regulate motor speed by controlling the frequency and voltage supplied to the connected 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 machine’s production requirements.

The specified dimensions of the ATV310HD22N4A are 390 × 180 × 212 mm, with an approximate product weight of 8.5 kg. Its larger enclosure accommodates the power components required for higher-power motor control while maintaining a practical format for industrial control cabinets.

The drive supports motor-control functions including U/F control and sensorless vector control. It can also be incorporated into PLC-based automation architectures through industrial communication functions, allowing motor operation and drive status to become part of the overall machine-control system.

With its combination of variable-speed operation, motor protection, adjustable control parameters, and industrial communication capability, the ATV310HD22N4A is suitable for OEM machinery, production equipment, material handling systems, conveyors, pumps, fans, and other industrial applications.

Technical Specifications

Function and Working Principle

The main function of the Schneider ATV310HD22N4A is to control the speed, acceleration, deceleration, and operating characteristics of a compatible three-phase asynchronous motor.

A conventional motor connected directly to a fixed-frequency power source generally operates at a speed determined by the supply frequency and motor design. A variable speed drive introduces electronic power conversion between the incoming electrical supply and the motor.

The ATV310HD22N4A can adjust the output frequency and voltage according to the required operating condition.

The basic power-conversion process can be represented as:

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

The drive converts the incoming electrical power into a controlled output that can be adjusted according to the motor-control parameters.

This allows the drive to provide:

• Variable motor speed
• Controlled acceleration
• Controlled deceleration
• Adjustable motor frequency
• Controlled starting
• Controlled stopping
• Torque regulation
• Motor protection
• Fault monitoring
• Communication with automation controllers

The ATV310HD22N4A supports U/F control and sensorless vector control.

U/F control is suitable for straightforward motor applications where the relationship between voltage and frequency is used to control the motor.

Sensorless vector control can provide more advanced motor-control performance without requiring a physical speed sensor mounted on the motor.

The drive also provides protective and monitoring functions designed to help identify abnormal operating conditions.

These can include:

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

For example, in a heavy-duty conveyor application, the PLC may issue a start command and speed reference to the drive. The ATV310HD22N4A then gradually increases the motor frequency according to the configured acceleration ramp.

During normal production, the PLC can change the speed reference when required. During shutdown, the drive can reduce the motor frequency according to the configured deceleration characteristics.

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

Role in Industrial Control Systems

The ATV310HD22N4A functions as the power-control interface between the automation controller and a higher-power three-phase motor.

A typical industrial automation system may include:

• Schneider Modicon PLC
• Schneider HMI
• ATV310HD22N4A 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
• Industrial communication gateway
• SCADA system
• Emergency stop circuit

The PLC processes information from field sensors and operator interfaces and determines the appropriate motor operating condition.

The ATV310HD22N4A receives the control commands and converts them into controlled motor operation.

Through Modbus RTU communication, the drive can exchange information with a compatible PLC or other automation controller.

Depending on the control architecture, the system can monitor:

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

This integration allows the variable speed drive to become an active part of the machine’s control strategy.

The motor does not necessarily need to operate at maximum speed continuously, allowing the machine control system to adjust fan operation according to process requirements.

Processing Machinery

Processing equipment may require different motor speeds during different stages of production.

The drive provides adjustable frequency control that can be incorporated into the machine’s overall automation sequence.

Installation and System Integration

Correct installation is important for achieving reliable operation of the ATV310HD22N4A.

Recommended installation practices include:

Important parameters can include:

• Motor rated voltage
• Motor rated current
• Motor rated frequency
• Motor rated speed
• Motor power
• Minimum frequency

• Acceleration time
• Deceleration time

Incorrect parameter settings can lead to excessive current, unstable motor operation, poor torque performance, or unnecessary protective trips.

Because the ATV310HD22N4A is a higher-power drive, cabinet thermal design should also be considered. Adequate airflow and sufficient installation clearance can help maintain acceptable operating temperatures.
