The Altivar Machine ATV320 series from Schneider Electric offers a wide range of Variable Speed Drives (VSDs) designed for industrial machine applications. The series includes IP66-rated drives for harsh environments, as well as IP65-rated drives with Vario options. These drives are built to ensure optimal performance and reliability in different industrial settings, particularly in applications that demand protection from dust, water, and other environmental factors.

Key Concepts:

• IP66: This rating means the drive is fully protected against dust and can withstand powerful water jets from any direction (e.g., from heavy rainfall or high-pressure washing).
• IP65: This rating means the drive is protected against dust and water jets from any direction (e.g., splashes or light washing), but it is not as water-resistant as the IP66 version.

IP66 Drive (Without Vario)

The IP66-rated Altivar Machine ATV320 drive is designed for harsh environments where the drive needs to be fully protected from dust and water. These drives are suitable for outdoor use, food processing environments, or any application where the drive could be exposed to high levels of dirt, water, or steam.

Features of the IP66 ATV320 Drive (Without Vario):

1. Environmental Protection:
   • IP66 Rating: Fully dust-tight and resistant to water from high-pressure jets.
   • Ideal for outdoor installations or areas where high levels of moisture, dust, or chemicals are present.
2. Durability:
   • Designed for heavy-duty applications in demanding environments such as mining, water treatment plants, food processing, and harsh industrial environments.
3. Motor Control:
   • Offers precise control of motor speed, acceleration, and deceleration for a wide variety of applications like pumps, fans, conveyors, and other industrial machines.
4. No Vario Option:
   • The IP66 ATV320 in this case does not include the Vario feature, meaning it does not have the flexible configuration options for specific machine control applications like with the Vario version.
   • This is a standard model that is simpler to configure and is typically used for more basic motor control applications.
5. Safety:
   • Integrated safety features, such as Safe Torque Off (STO) and Safe Stop 1 (SS1), to protect both the machine and operator from unexpected faults or shutdowns.
6. Applications:
   • Perfect for outdoor installations or high-pressure wash-down environments, such as pumping stations, HVAC systems, water treatment plants, and general industrial automation.

Summary of IP66 Drive Features:

• Rating: IP66 (dust-tight, water-resistant to high-pressure jets)
• Protection: Suitable for extreme environmental conditions
• Applications: Outdoor use, high-moisture environments, food processing, general industrial applications
• Vario Option: Does not include Vario features (basic motor control)
• Safety: Includes integrated safety features (STO/SS1)

IP65 Drive with Vario

The IP65-rated Altivar Machine ATV320 drive with the Vario option provides a more flexible and customizable solution for industrial automation applications. The Vario option refers to the additional capability of configuring the drive with more advanced machine control functions such as control blocks for specific applications (e.g., pumps, fans, conveyors, etc.), as well as enhanced communication and configuration flexibility.

Features of the IP65 ATV320 Drive (With Vario):

1. Environmental Protection:
   • IP65 Rating: The drive is protected against dust and can withstand water splashes or low-pressure water jets, making it suitable for most industrial environments but not as rugged as the IP66 version.
   • Ideal for indoor environments or locations where occasional moisture exposure might occur but where the drive doesn't need to endure heavy wash-downs or outdoor conditions.
2. Vario Option (Flexible Machine Control):
   • The Vario option refers to Schneider Electric’s pre-configured machine control blocks, which are available for configuring the drive to suit specific applications (e.g., pump control, fan control, conveyor control, etc.).
   • This flexible control block system allows the drive to be easily configured for different machine functions, reducing the need for external PLCs or complex programming.
3. Advanced Control and Communication:
   • Offers advanced motor control features for high-performance applications.
   • Communication options such as Modbus, Ethernet/IP, CANopen, and others, enabling seamless integration with other automation systems, PLCs, HMIs, and sensors.
4. Energy Efficiency:
   • Designed to optimize energy consumption by adjusting the motor's speed to match the load requirements. The Vario option supports energy-saving features, which help reduce operational costs in applications like HVAC, pumps, and conveyors.
5. Safety:
   • Includes integrated safety features like Safe Torque Off (STO) and Safe Stop 1 (SS1), ensuring safe operation of the machinery and protecting both operators and equipment.
6. Applications:
   • Commonly used in indoor industrial environments where machines need flexible control for a variety of applications, such as conveyors, HVAC systems, pumps, and other automated systems.

Summary of IP65 Drive with Vario Features:

• Rating: IP65 (dust-tight, water-resistant to low-pressure jets)
• Protection: Suitable for indoor use and moderate exposure to moisture
• Applications: Conveyor systems, HVAC, pumps, fans, and flexible machine control applications
• Vario Option: Includes flexible, pre-configured control blocks for various machine functions
• Advanced Control: Energy-saving features, advanced communication, and motor control
• Safety: Integrated safety features (STO/SS1)

Comparison of IP66 Drive Without Vario vs IP65 Drive With Vario

Conclusion

• IP66 Drive (No Vario): The IP66-rated ATV320 is ideal for harsh environments like outdoor installations, areas with high dust levels, and applications requiring high-pressure washdowns. It’s a robust solution that provides reliable motor control without the need for advanced machine control features.
• IP65 Drive (With Vario): The IP65-rated ATV320 with Vario provides a more flexible and customizable solution, especially in indoor environments. The Vario option enables the use of pre-configured machine control blocks and advanced motor control, making it ideal for applications like pumps, fans, and conveyors. It also offers a wider range of communication options for integration into complex automation systems.

Both drives are suitable for industrial machine applications, but the choice between IP66 and IP65 will depend on the environmental conditions and the level of control required. If you're looking for a simple, rugged solution for harsh outdoor environments, the IP66 drive is the better choice. For more flexible control and integration with other automation systems, the IP65 drive with Vario will provide more customization options.
