Description
MITSUBISHI ELECTRIC LE7-DCA — Roll Diameter Calculation Option (for LE7-40GU-L), genuine MITSUBISHI ELECTRIC product.
Overview
The LE7-DCA is a roll diameter calculation option from Mitsubishi Electric for the LE7-40GU-L tension controller. It calculates the changing diameter of a winding or unwinding roll from line speed and rotation signals, so the controller can adjust torque to keep web tension steady as the roll grows or shrinks. It is used on film, paper, foil and textile winders.
Key Features
- Calculates roll diameter during winding
- Improves tension stability as diameter changes
- Option for the LE7-40GU-L controller
- Supports winding and unwinding control
