Tension Controls VERSATEC® Free Loop Applications Powered Unwinds Free Loops The VERSATEC is a fully automatic non-contact Free Loop control. The machine operator simply enters the desired distance for the minimum and maximum outputs and the desired loop position using the keypad. The VERSATEC then controls the loop position by ultrasonically measuring the actual position and commanding the necessary output to achieve and maintain the desired position. The VERSATEC program is optimized for speed control applications, and will control an AC or DC drive or servo to maintain the loop position. The multi-line display indicates the setpoint and actual position simultaneously, and simplifies setup and operation. Position adjustments may be made from the VERSATEC keypad, through remotely mounted push buttons, or through a PLC. Its responsiveness to position changes is easily optimized for any system. Two alarm outputs can be adjusted to alert the operator before an out of range condition occurs, and an adjustable hysteresis feature prevents the alarms from chattering due to small changes in loop position. Features Provides closed loop control of Free Loops for tension isolation Optimized for speed control applications Controls an AC or DC drive or servo to maintain loop position Multi-line display indicates setpoint and actual loop position simultaneously Loop position is controlled to an adjustable setpoint Ultrasonic sensor never touches the web Two alarm setpoints alert the operator when the loop reaches preset limits Standard opto-isolated control inputs and outputs allow the VERSATEC to interface with PLCs, and AC & DC drives.
