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.
