Mitsubishi FR-A800-R2R INVERTER

DESIGNED FOR WIND/UNWIND APPLICATIONS

KEY FEATURES:

Dancer control function – PID control function keeps the dancer roll position and eliminates hunting, allowing for efficient wind/unwinding applications.

Winding diameter compensation function – Speed and torque is controlled to allow for changes in the diameter of the winding and unwinding shafts during operation for quick and easy system setup.

Tension control (inertia compensation/mechanical loss compensation) – Torque required for acceleration/deceleration and the mechanical loss compensation torque are controlled, keeping material tension constant and reducing wrinkling or deformations within the material roll.

Dancer PI automatic tuning function – Optimum PI gain is automatically set by the inverter, reducing system startup time

Speed control proportional gain compensation function – Actual response level is corrected along with changes in the inertia ratio of the winding/unwinding shafts improving the tracking ability to automatically allow for changes in the diameter, contributing to overall cost savings of the system.
