Product Overview

The Schneider Electric ATV320U07M2B 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 designed for a 200–240 V AC single-phase power supply and provides a 0.75 kW (1 HP) motor rating for heavy-duty applications. It converts the incoming fixed-frequency AC supply into a controlled three-phase output, allowing a compatible motor to operate at adjustable speed and torque.

The ATV320U07M2B uses the Book-format mechanical design of the ATV320 family. Its specified dimensions are 45 × 325 × 245 mm, with an approximate weight of 2.4 kg. The narrow enclosure is particularly useful in electrical cabinets where horizontal space is restricted and a vertically oriented drive is preferred.

The drive is designed for machine applications that require more sophisticated motor control than a conventional contactor or direct-on-line starter. It provides controlled acceleration and deceleration, adjustable motor speed, motor protection, braking capability, communication functions, and machine-oriented safety features.

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

Technical Specifications

Function and Working Principle

The ATV320U07M2B controls the speed and torque of a connected three-phase AC motor by regulating the frequency and voltage of its output.

The basic power-conversion process is:

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

The incoming single-phase AC supply is converted internally into DC power. The inverter section then produces a controlled three-phase output for the motor.

By changing the output frequency, the drive can change the motor speed. Voltage and current are also regulated to maintain appropriate motor torque.

The ATV320U07M2B can therefore provide:

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

Sensorless flux vector control can provide improved torque and speed performance when compared with basic V/F operation in suitable applications.

This makes the ATV320U07M2B appropriate for machinery where motor performance needs to remain stable across a range of operating speeds.

Role in Industrial Control Systems

The ATV320U07M2B typically acts as the motor-control interface between a single-phase industrial electrical supply and a three-phase AC motor.

A simplified machine-control architecture is:

PLC / Controller → ATV320U07M2B → Three-Phase Motor → Machine Mechanism

The PLC manages the machine sequence, while the drive handles motor speed and torque control.

For example, a PLC may command a conveyor motor to operate at different speeds depending on product flow. The ATV320U07M2B receives the speed reference and generates the appropriate motor output.

The drive can also provide feedback to the automation controller.

Typical operating data includes:

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

This allows the controller to monitor the motor-control system and respond to abnormal operating conditions.

The combination of PLC control and variable speed drive technology is particularly useful in OEM machinery because it provides greater flexibility than fixed-speed motor control.

Industrial Applications

Conveyor Systems

The ATV320U07M2B can control motors used in conveyor systems for manufacturing, packaging, assembly, and material handling.

Adjustable speed allows the conveyor to synchronize with other machine operations.

Controlled acceleration and deceleration can also reduce mechanical shock to belts, rollers, gears, and transported products.

Packaging Machinery

Packaging equipment often requires variable motor speed for feeding, indexing, conveying, positioning, and other machine functions.

The ATV320U07M2B can provide controlled motor operation while allowing the PLC to coordinate the complete packaging process.

Pumps

Small industrial pumps can use variable speed operation to adjust flow according to process requirements.

This provides greater flexibility than operating the pump continuously at a fixed speed.

Fans and Ventilation Equipment

The drive can regulate compatible fan motors used in industrial ventilation and cooling systems.

Adjustable speed allows airflow to be matched more closely to actual operating requirements.

Feeders

The ATV320U07M2B can control motors used in feeding and dosing equipment where material flow needs to be adjusted.

Material Handling

Small rollers, transfer mechanisms, feeders, and other material-handling equipment can use the drive for adjustable motor speed.

Textile Machinery

Textile equipment can require controlled speed for winding, feeding, and material transportation.

The ATV320U07M2B can provide the necessary variable speed control for compatible applications.

OEM Machinery

The narrow 45 mm Book-format enclosure makes this model particularly attractive for OEM machine builders working with cabinets where available width is limited.

Installation and System Integration

Proper installation is essential for reliable drive operation.

Before installing the ATV320U07M2B, engineers should verify:

• Single-phase input voltage
• Motor rated voltage
• Motor rated current
• Motor power
• Motor frequency
• Grounding
• Circuit protection
• Motor cable size
• Control wiring
• Cabinet ventilation
• EMC requirements
• Communication configuration

The ATV320U07M2B is designed for a 200–240 V AC single-phase supply, so the available electrical supply must be checked before connection.

Typical Installation Procedure

1. Disconnect and isolate the incoming electrical supply.
2. Verify that no hazardous voltage remains.
3. Mount the drive securely inside the control cabinet.
4. Install the drive in the recommended vertical orientation.
5. Maintain appropriate ventilation clearance.
6. Connect the single-phase AC input.
7. Connect the three-phase motor output.
8. Connect protective grounding.
9. Connect control inputs and outputs.
10. Connect communication wiring if required.
11. Enter the motor nameplate data.
12. Select the appropriate motor-control mode.
13. Configure acceleration and deceleration ramps.
14. Configure motor protection parameters.
15. Perform motor auto-tuning where applicable.
16. Verify motor rotation direction.
17. Perform a low-speed motor test.
18. Verify PLC communication.
19. Check alarms and fault indications.
20. Test the complete machine.

Because the drive operates with a single-phase input but provides a three-phase motor output, the input and motor wiring must be connected according to the correct drive configuration.

Communication and Control Integration

The ATV320U07M2B provides communication functions for integration into automated machinery.

Modbus serial communication can be used to exchange control commands and operating information with compatible controllers.

CANopen provides an additional communication method for distributed machine-control applications.

Communication can be used to exchange:

• Start commands
• Stop commands
• Speed references
• Frequency feedback
• Motor current
• Drive status
• Warning information
• Fault information
• Diagnostic information
• Parameter data

The ATV320 platform also supports additional communication options through suitable interface modules, allowing integration into different industrial automation architectures.

This makes the ATV320U07M2B suitable for both standalone machine sections and coordinated multi-drive systems.

Compatible System Components

The ATV320U07M2B can be combined with various industrial automation and electrical components.

The appropriate accessories should be selected according to the motor, electrical supply, braking requirements, EMC conditions, communication network, and machine safety design.

Recommended Alternative Models

The following ATV320 models may be considered for similar applications.

The ATV320U04M2B can be considered for applications requiring approximately 0.37 kW, while the ATV320U06M2B is suitable when approximately 0.55 kW is sufficient.

When replacing an existing drive, engineers should verify the motor rated current, input configuration, overload requirements, mounting dimensions, communication functions, braking requirements, and application duty.
