Output level bias
This item should normally be set to 0%.
Output level limit
The procedure for establishing this value is explained in Controller Tuning, below.
Set point ramp rate
It may cause an unacceptable disturbance and be unsafe if the tension is changed too quickly.
Enter a value which is slightly slower than the PI stability rate so that the system can maintain the
desired tension value as the set point is changed.
Display damping time
If the tension is fluctuating enter a value between 0.1 and 3 seconds so that the display is steady.
The Display Damping operates on the analog bar graph and the digital display.
Display precision
(1, 5, 10 ( 0.1, 0.5 and 1 for percent units ))
Enter a value so the display can be read easily and the tension set point easily entered. This item
also sets the resolution of the tension set point value.
Right transducer
(Disabled, Enabled)
Select "Disabled" when a single transducer is used, for example in wire and cable or narrow web
applications. The single transducer must be connected to the "Left" terminals using TB3.
Line Tacho or Encoder *
(Essential for Speed and Torque modes)
If an encoder is selected enter the maximum number of pulses per second when the machine is
at maximum speed. This allows for the encoder pulses per revolution and the gear ratio used.
Enter the number of pulses per metre or foot if the Length Counter feature is required. The
maximum number of pulses allowed is 9999 pulses/metre or 3000 pulses/foot.
The tacho or encoder must be Enabled in order to function.
Winder Tacho or Encoder *
(Essential for Speed and Torque modes)
If an encoder is selected enter the maximum number of pulses per second when the machine is
at maximum speed. This allows for the encoder pulses per revolution and the gear ratio used.
The tacho or encoder must be Enabled in order to function
All Machine Parameters and Product Parameters, including the current TENSION SET POINT value are
saved to non-volatile memory. This ensures that when the Controller is switched off or if the power is
removed, the parameters are saved.
