The EasyWeb™ is an open loop torque controller designed to maintain constant web tension or provide taper tension to center driven rewind or unwind applications.
Web tension is regulated by controlling motor or brake torque based on varying levels of roll diameter. An Inertia compensation parameter is provided to obtain greater control of web tension during changes in line speed.
The EasyWeb can accept signals from a direct diameter sensor or calculate diameter using line and roll speed signals. The user interface provides a bright OLED display for easy viewing in any lighting and viewing angle, while a large front dial allows fast, easy scrolling through the user menu.
The jumper selectable 0-10VDC or 4-20mA control output allows the EasyWeb to control a variety of torque devices to regulate web tension including brakes, clutches, and motors. Output modes are designated as follows:
Drive output (D): 0-10Volt DC compensated output.
Used to control AC or DC drives or other variable speed
drive systems. This output is isolated from earth ground
to make it more compatible with all drives.
Pneumatic output (P): Used to actuate any airoperated
brake or clutch. The standard version includes
a servo valve and pressure regulator installed in a
High Voltage output (V): Uses Silicon Controlled
Rectifiers (SCR's) to produce a standard variable
voltage of up to 90Vdc to operate any electric brake or
clutch, including eddy current clutches.
Organic LED display
