Product Overview

The Schneider Electric ATV320U11M2B Variable Speed Drive is an Altivar Machine ATV320 frequency inverter designed for variable speed control of AC motors in industrial machinery, OEM equipment, and automated production systems.

This model is rated for 1.1 kW (1.5 HP) motor applications and is designed for a 200–240 V AC single-phase power supply. It provides controlled motor acceleration, deceleration, speed regulation, torque control, motor protection, braking capability, and communication functions.

The ATV320U11M2B uses the Book-format enclosure of the ATV320 product family. Its specified dimensions are 60 × 325 × 245 mm, with an approximate weight of 2.9 kg. The narrow enclosure is especially useful for machine control cabinets where installation width is limited but a full-featured variable speed drive is required.

The drive is suitable for controlling both compatible asynchronous and synchronous motors. It can operate as a standalone motor controller or as part of a larger PLC-based automation system.

Typical applications include conveyors, packaging machines, feeders, pumps, fans, material-handling systems, textile equipment, lifting-related machinery, and general OEM automation.

Technical Specifications

Function and Working Principle

The main function of the ATV320U11M2B is to regulate the speed and torque of a connected three-phase AC motor.

The drive receives 200–240 V single-phase AC power and internally converts the electrical energy into a controlled three-phase output for the motor.

The basic power-conversion process is:

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

The rectifier converts the incoming AC supply into DC power. The DC link provides the intermediate energy storage stage, while the inverter section converts the DC voltage into a controlled three-phase AC output.

By changing the output frequency and voltage, the drive can regulate motor speed and torque.

The ATV320U11M2B can therefore provide:

• Adjustable motor speed
• Controlled acceleration
• Controlled deceleration
• Soft starting
• Controlled stopping
• Torque management
• Low-speed operation
• Motor current monitoring
• Motor overload protection
• Dynamic braking
• Fault detection
• Alarm monitoring
• Speed reference control
• PLC-based motor control

The ATV320 platform supports sensorless flux vector control, which provides improved motor torque performance compared with simple V/F control in suitable applications.

This is particularly useful for machines where the motor must maintain stable operation over a relatively wide speed range.

Role in Industrial Control Systems

The ATV320U11M2B typically operates as the motor-control interface between the machine’s electrical supply and its motor.

A typical industrial architecture can be represented as:

PLC / Controller → ATV320U11M2B → Three-Phase AC Motor → Mechanical Load

The PLC controls the overall machine sequence, while the ATV320U11M2B performs the detailed electrical control of the motor.

For example, a PLC can send a speed reference to the drive when a conveyor needs to increase or decrease its operating speed. The ATV320U11M2B converts this reference into the corresponding motor frequency and voltage.

The drive can also provide operating information back to the controller.

Typical feedback data includes:

• Motor frequency
• Motor current
• Speed reference
• Drive status
• Warning status
• Fault status
• Operating state
• Diagnostic information

This creates a closed information path between the machine controller and the motor-control system.

In applications using multiple motors, several ATV320 drives can be coordinated by a PLC or industrial network. Each drive can control an individual motor while the controller synchronizes the overall machine process.

Industrial Applications

Conveyor Systems

The ATV320U11M2B can control conveyor motors used in manufacturing, assembly, packaging, and material-handling systems.

Adjustable speed allows the conveyor to synchronize with other production equipment.

Controlled acceleration and deceleration can also help reduce mechanical stress on belts, rollers, couplings, and gear systems.

Packaging Machinery

Packaging equipment frequently requires variable motor speed for feeding, indexing, conveying, and positioning.

The ATV320U11M2B can provide controlled motor operation while allowing the PLC to manage the complete packaging sequence.

Feeders

Industrial feeders may require different motor speeds according to production demand.

The drive allows the motor speed to be adjusted without changing the mechanical transmission ratio.

Pumps

The ATV320U11M2B can control compatible pump motors where flow or pressure needs to be adjusted according to process requirements.

Variable speed operation can provide more flexible control than a fixed-speed motor arrangement.

Fans and Ventilation Systems

Industrial fans can be operated at different speeds according to cooling or ventilation requirements.

The drive can regulate the fan motor according to the machine’s control strategy.

Material Handling

Rollers, transfer systems, lifting mechanisms, feeders, and other material-handling equipment can use variable speed motor control.

Textile Machinery

Textile machines can require stable and adjustable motor speeds for winding, feeding, and material transportation.

The ATV320U11M2B can provide the required speed-control capability for compatible equipment.

OEM Machine Building

The 60 mm-wide Book-format enclosure makes the drive suitable for OEM machinery where cabinet width is limited.

Machine builders can integrate the drive into a centralized control cabinet together with PLCs, HMIs, circuit protection, sensors, and communication equipment.

Installation and System Integration

Correct installation is essential for reliable and safe operation.

Before installing the ATV320U11M2B, engineers should verify:

• Single-phase input voltage
• Motor rated voltage
• Motor rated current
• Motor rated power
• Motor frequency
• Protective grounding
• Circuit protection
• Motor cable size

17. Perform a low-speed test.
18. Check the drive’s status and diagnostic information.
19. Verify communication with the PLC or controller.
20. Perform a complete machine test.

The ATV320U11M2B includes an integrated EMC filter, which can simplify EMC design compared with a drive that requires a separate input EMC filter. However, the complete installation must still follow the machine’s grounding, cable routing, shielding, and EMC requirements.

Communication and Control Integration

The ATV320U11M2B supports communication functions for integration with industrial automation systems.

Standard communication capabilities include:

• Modbus Serial
• CANopen

Optional communication modules can provide additional industrial networking capabilities.

Depending on the selected communication option, the drive can be integrated with networks such as:

• PROFIBUS DP V1
• PROFINET
• EtherNet/IP
• EtherCAT
• DeviceNet
• Ethernet Powerlink
• CANopen

Communication allows the PLC or supervisory controller to exchange information with the drive.

Typical control and monitoring data includes:

• Start command
• Stop command
• Speed reference
• Frequency reference
• Motor current
• Drive status
• Warning status
• Fault status
• Diagnostic information
• Parameter values

This allows the drive to become an integrated part of the machine automation system.

For example, a PLC can command the ATV320U11M2B to run at a specific speed, monitor its operating status, detect a fault, and initiate a controlled machine response.

Compatible System Components

The ATV320U11M2B can work together with a range of Schneider Electric and compatible industrial automation components.

Accessory selection should be based on the actual motor, electrical supply, braking requirements, EMC conditions, communication architecture, and machine safety design.

Recommended Alternative Models

The following ATV320 models may be considered for applications with similar motor-control requirements.

The ATV320U07M2B is appropriate when approximately 0.75 kW of motor capacity is sufficient.

The ATV320U15M2B can be considered when a 1.5 kW motor is required, while the ATV320U22M2B provides a higher 2.2 kW power level.

For applications with three-phase 200–240 V input, the ATV320U11M3C is a relevant alternative. When the machine uses a 380–500 V three-phase supply, the ATV320U11N4B may be more appropriate.

For replacement applications, the motor rated current should be checked rather than selecting a replacement solely according to motor power. Input voltage, overload duty, physical dimensions, communication requirements, EMC configuration, braking requirements, and safety functions should also be verified.
