Revision BA
WebPro Motor Powered Unwind Tension Controller
Language
(English, Deutsch, Français, Italiano, Español)
The default language is English. If changed, all text shown on the Controller will be changed to
that language and an extra item "5 - Translations" will be added to the Introduction screen.
Unit system
(SI (newtons), Kgf, pounds/foot, percent)
Select a unit system. All items which use units will be changed accordingly.
Unwind type
(Brake, Torque, Speed)
Select the unwind type. In Torque and Speed control modes tachos or encoders must be
available for the line speed and winder (reel) speed signals in order to calculate the reel diameter.
Start in control screen
(No / Yes)
The Controller is despatched from the factory with this set to "No". We recommend that after all
commissioning and set up is finished that this is then set to "Yes". When the Controller is now
switched on, the program is loaded, the company logos are shown briefly and then the Control or
operating screen ready for use by the operator.
Enable MAN / AUTO / OFF keys
(No / yes)
When using the Digital Inputs to control the sequence of the system, this item should be set to
"No" to prevent accidental operation.
Dual tension range
(No / Yes)
Select "Yes" if required. Enter two values of tension. The (normal) value must be the same value
as entered during Calibrate tension. The (low) value should not be less than one third of the
(normal) value. Terminal TB4/11 will be switched OFF when LOW is selected from the front
panel.
TB4/11 is an open drain mosfet which may be used with a suitable electrical relay to select the
motor torque range when in Torque control. See Digital Output Connections for more details.
Minimum tension
Enter a value, the minimum tension is 3%, the maximum is 20%. The system may not function
correctly and may be unsafe if it is operated at zero tension (the motor may run forwards).
Static friction
(For Torque mode only)
Enter a value which overcomes the unwind static friction.
The procedure for establishing this value is explained in Controller Tuning - Torque mode, below.
Dynamic friction
(For Torque mode only)
Enter a value which overcomes the unwind dynamic friction.
The procedure for establishing this value is explained in Controller Tuning - Torque mode, below.
