The Altivar Machine ATV320 series from Schneider Electric is a specialized range of Variable Speed Drives (VSDs) designed for industrial machine applications. These drives are equipped with various features that help optimize motor control, improve performance, and reduce energy consumption. One important feature of the Altivar Machine ATV320 is its built-in control block for machine control functions.

Altivar Machine ATV320 with Control Block

In the context of machine control, the ATV320 series is equipped with a Control Block, which is essentially a pre-configured set of control logic and functions for specific industrial applications. These control blocks provide flexibility for managing common machine functions without the need for additional external PLCs (Programmable Logic Controllers) or other control systems. The control block typically handles basic machine control tasks like start/stop, speed control, torque management, and safety functions.

Key Features of the Altivar Machine ATV320 Drives with Control Block:

1. Pre-Configured Control Blocks:
   • The Altivar Machine ATV320 comes with built-in control blocks that can be easily configured to handle specific machine functions, such as:
     • Start/Stop control
     • Speed control(via analog or digital inputs)
     • Torque control
     • Acceleration/Deceleration ramps
     • Motor protection functions
     • Regenerative braking
2. Programmable Logic:
   • The control block in the ATV320 series allows users to program specific behaviors for motor control. These blocks offer machine-level control logic in a simplified and modular form, providing a cost-effective solution for applications that traditionally would have required a separate PLC.
3. Built-In Application Functions:
   • Pre-configured applications such as pump control, fan control, conveyor belt control, and crane control are included. These application templates can be easily customized to match specific operational needs.
4. Flexible Communication:
   • The ATV320 supports various communication protocols, including Modbus, Ethernet/IP, CANopen, and others. This ensures compatibility with other devices, like HMIs (Human-Machine Interfaces), sensors, or higher-level controllers.
5. Safety Functions:
   • The ATV320 includes essential safety features such as safe torque off (STO) and safe stop 1 (SS1), which are part of the drive's integrated safety functions. These help protect personnel and machinery by ensuring that the motor is safely stopped in case of an emergency.

Book Control Block for ATV320:

The Book Control Block refers to the pre-configured logic blocks within the Altivar Machine ATV320 series that help streamline the setup and programming of machine functions. Schneider Electric’s control blocks are essentially templates or "modules" that allow users to quickly implement a wide range of motor control functions without needing to write complex control logic from scratch.

What is a Book Control Block?

The term "Book Control Block" isn't a formal Schneider Electric term but may refer to the following:

• Control Block Templates: These are reusable, modular pieces of logic embedded in the ATV320 drive that handle typical machine control functions. These templates can be considered as "pre-configured blocks" of logic, providing a foundation for faster deployment and setup.
• Simplified Programming: Instead of programming the drive from scratch, you can utilize these control blocks to implement specific machine functions based on your needs. This makes it easier to set up more complex machine behaviors.

Typical Control Blocks and Functions in ATV320:

Here are examples of common machine control blocks that might be found in the Altivar Machine ATV320 drives:

1. Speed Control Block:
   • Controls motor speed by adjusting the frequency of the drive’s output, based on a reference input (such as an analog signal or digital input).
   • Adjustable acceleration and deceleration ramps.
2. Torque Control Block:
   • This block is used for controlling the torque delivered to the motor. It’s typically useful in applications like winding machines, where precise torque control is critical.
3. Start/Stop Control:
   • A simple block that provides the logic for starting or stopping the motor based on input conditions (e.g., a push button, digital input signal).
4. Ramp Control:
   • Controls the rate of change of speed. This is especially useful in applications where motors should ramp up or slow down gradually to prevent mechanical shock or damage.
5. Pump Control:
   • A pre-configured block that helps with the operation of pumps, including functions like dry run detection, flow control, and pressure regulation.
6. Fan Control:
   • Designed for applications where motor speed needs to be controlled in response to changing load conditions. Fans often require dynamic speed adjustment to match varying demand.
7. Conveyor Belt Control:
   • A block specifically designed for conveyor systems, where the speed of the motor may need to change based on load, product type, or other system parameters.
8. Safety Control Block (STO/SS1):
   • Provides safety control logic for critical functions, ensuring that the drive’s operation is disabled in an emergency or fault condition.

ATV320 Control Block Programming:

The ATV320 can be programmed using the built-in keypad or remotely via communication protocols(Modbus, CANopen, Ethernet/IP). You don’t need a separate PLC to implement basic machine control functions, as the ATV320 integrates this functionality.

Configuration Options:

1. Keypad Configuration: The built-in keypad allows users to navigate through the control blocks and easily configure the settings. Parameters such as speed limits, acceleration/deceleration ramps, and motor protection can be set directly via the keypad.
2. EcoStruxure™ Machine Expert: For more complex configurations, Schneider Electric offers EcoStruxure™ Machine Expert(formerly known as SoMachine), a software platform that allows you to design, program, and configure control functions in more detail. It provides a graphical interface for configuring and programming logic blocks.
3. SoMove Software: SoMove is Schneider Electric’s configuration and monitoring tool for drives. While EcoStruxure is more advanced, SoMove is an intuitive tool for basic setup, parameter adjustments, and drive diagnostics.

Benefits of Control Blocks in ATV320:

1. Faster Setup: Pre-configured blocks simplify the setup process for common machine control tasks.
2. Reduced Need for External Controllers: The built-in control logic reduces the need for additional PLCs or controllers.
3. Flexibility: The control blocks can be customized for a wide variety of industrial machine applications.
4. Optimized Performance: Functions like torque control, ramping, and motor protection help optimize performance and protect the motor and machinery.
5. Integration: Easy integration with other Schneider Electric products (e.g., HMIs, PLCs, sensors) via standard communication protocols.

Conclusion:

The Altivar Machine ATV320 series with control blocks provides a comprehensive, user-friendly solution for motor control in industrial machine applications. The built-in control blocks make it easy to implement common control functions without the need for additional external controllers, such as a PLC. By using pre-configured application templates, users can reduce setup time and improve the overall efficiency of their machines.
