Setup of pilot control
The pilot control enables to evaluate the actual reel diameter and to calculate the brake
torque or drive power adapted to the reel diameter (pilot control signal). In addition,
the PID control parameters are dynamically adapted to the reel diameter continuously.
Therefore the controller is only responsible for the material tension variations. This
will increase control loop stability.
Setup of pilot control is done as written under „10.3 Setup of pilot control“.

Taper Function
fig. 18: Characteristic curve of the taper function
C433007e
If the end of the reel should be wound smoother than the centre of the reel, a taper
function can be parametrized. The characteristic curve can be chosen as a linear,
square or square root function (fig. 18). But the taper function is only active if the pilot
control is also active, that means the controller must know the actual reel diameter.
