Parameter Descriptions
37-42 Tapered Tension Change Rate
Sets the amount of tapered tension that can change during each
scan period. This function ramps the tapered tension setpoint to
the preset value when the user changes either the tension or
taper setpoints. This ensures stability during step changes in
setpoints.
Range:
0.1 % [0.1 - 1 %]
*
37-43 Diameter Calculator Min Speed
Sets the minimum line speed to be achieved before the diameter
calculator is activated. At low line speeds, the resolution of the
line and winder speed are too low for the diameter to be
accurately calculated.
Range:
0 % [0 - 100 %]
*
37-44 Line Acceleration Feed Forward
Sets the feed forward speed that helps compensate for tension
changes caused by line speed acceleration and deceleration.
Range:
0 [-20 - 20 ]
*
37-45 Line Speed Source
Use this parameter to set the input for line speed.
Option:
[0] No function

37-46 Winder Speed Match Scale
This parameter is used to match the surface speeds of line and
winder at smallest core while running line at 100 % speed.
Range:
1 [0.001 - 1000 ]
*
37-47 Tension PID Profile
Allows scaling the tension loop PID output to compensate for roll
diameter. Ideally, the output from the tension loop PID amplifier
is halved each time the diameter doubles, which is considered
fully profiled. In some cases, it might be desirable to be less than
fully profiled, which would give over compensation when the
diameter increases.
Range:
0 % [0 - 100 %]
*
37-48 Tension PID Proportional Gain
Sets the proportional gain for tension loop PID amplifier.
Range:
0 [0 - 10 ]
*

Programming Guide
37-49 Tension PID Derivate Time
Sets the derivative time for tension loop PID amplifier.
Range:
0 s
37-50 Tension PID Integral Time
Function:
Sets the integral time for tension loop PID amplifier.
Range:
501 s
37-51 Tension PID Out Limit
Sets the maximum tension PID loop output that can be added to
the open loop speed reference. The value is normally set to limit
the contribution of the tension PID loop to 10% of the maximum
Function:
reference speed.
Range:
0 %
37-52 Tension PID Der Gain Limit
Sets the limit for derivation gain in tension loop PID amplifier.
Function:
Range:
5

37-56 New Diameter Select
Selects partial roll diameter as the preset starting diameter when
the diameter reset is energised, rather than using one of the 2
preset core diameters.
