Tension control for fast changeovers
MAGPOWR
CYGNUS Tension Control provides the ability to store multiple setups (recipes) for different materials, allowing quick changeover without re-tuning the control for each material. Built-in Ethernet, ProfiBus-DP, or DeviceNet bus protocols allow an infinite number of setups and complete control through a human-machine interface. Eliminate the process of hanging weights over the sensing roll with weightless load cell calibration. To optimize roll stability from start to finish, automatic gain compensation measures the diameter of the roll and automatically adjusts the tuning parameters for virtually any roll build ratio. Out-of-round roll compensation ensures consistent tension when the quality of the unwind roll is compromised. Taper tension features automatically reduce tension as the roll builds to eliminate roll telescoping.
