AO-70172 16 Revision BA
WebPro Motor Powered Unwind Tension Controller
Calibrate Speed
Note - During Calibrate speed the controller will not provide an output signal. To carry out the Calibrate
speed disconnect the controller Control Out TB4/5 to the unwind drive and connect a suitable signal to
the unwind drive direct speed input to represent the maximum unwind speed. This signal can usually be
sourced from the unwind drive. Reconnect the controller when the Calibrate speed is completed.
From the Commissioning Menu; press 3 to show the Calibrate speed screen.
Follow the on screen prompts. Note the Tension must be calibrated before the Speed is calibrated.
Possible error messages:
Calibration has failed. Either the speed was much too low for accurate
calibration, or the tachos and/or encoders are not operating correctly.
Press the SET UP key to return to the Commissioning menu
Calibration aborted.
This is shown if the SET UP key is pressed. The Controller will return to the Commissioning Menu screen.
Tension must be calibrated before speed.
Select Calibrate tension from the menu.
The controller has not been calibrated or the settings are no longer
valid. Press any key to continue.
Product Parameters
The default is Product Number 1.
Product # Parameters (SET UP = cancel)
Minimum diameter Enter a value
Full scale diameter Enter a value
Length outputs Disabled, Enabled
Preceding length ( if a line encoder is available )
Full length ( if a line encoder is available )
PI stability setting *
Inertia time constant ( if a line tacho or encoder is available )
Inertia coefficient ( if a line tacho or encoder is available )
Maximum trim ( Speed and Torque control modes only )
An asterisk * indicates that a further menu will open if this item is selected.
Enter a value for the Minimum Diameter (core) using the selected units.
Enter a value for the Full Scale Diameter (maximum) using the selected units.
If an encoder is available enable the Length Outputs and set the Preceding Length and Full Length.
The procedure for the PI stability settings and Maximum trim is explained in Controller Tuning, below.
