Features
The Mitsubishi FR-A800-R2R is a specialized variable frequency drive (VFD) designed for roll-to-roll applications. This means it’s optimized for processes involving continuous winding and unwinding of materials like paper, film, fabric, or metal foil. Think of applications like printing presses, packaging machines, or textile manufacturing.
Key Features and Benefits:
- Precise Tension Control: This is the core function. The drive maintains consistent tension on the material being wound or unwound, preventing issues like wrinkles, stretching, or breakage. It achieves this through:
- Automatic Winding Diameter Calculation: The drive constantly calculates the diameter of the winding and unwinding rolls, adjusting speed and torque accordingly.
- Tension Sensor Feedback: It can use feedback from tension sensors to fine-tune control and ensure even greater accuracy.
- Dancer Control: For systems with a “dancer” roll (a roll that moves to buffer tension variations), the FR-A800-R2R can precisely control the dancer’s position.
- Specialized Control Modes: It offers specific control modes for different stages of the winding/unwinding process, such as:
- Constant Tension Control: Maintains consistent tension during steady-state operation.
- Taper Control: Gradually reduces tension as the roll diameter increases (or decreases), which is often needed for certain materials.
- Built-in Functions: The FR-A800-R2R includes built-in functions that simplify setup and operation, such as:
- Automatic Dancer PI Tuning: Automatically adjusts control parameters for optimal performance.
- Sensorless Torque Control: Can estimate and control torque even without a separate torque sensor.
- Energy Efficiency: Like other FR-A800 series drives, it incorporates energy-saving features like Optimum Excitation Control.
Why These Features Matter for Roll-to-Roll Applications:
- Improved Product Quality: Consistent tension leads to higher quality end products, free from defects caused by uneven winding.
- Increased Productivity: Precise control and automation features enable faster processing speeds and reduced downtime.
- Reduced Material Waste: Minimizing tension-related issues reduces material waste due to damage or imperfections.
- Simplified Setup and Operation: Built-in functions and user-friendly parameters make it easier to configure and operate the drive.
