Danfoss VLT 5005 - Torque Control, Speed Feedback

Torque control, speed feedback
A winder winds material onto a roll or unwinds material
from a roll at a constant tension.
A device measures the radius of the roll and adjusts
the motor torque to ensure that the tension is constant.
The measuring device must have a non-linear output
signal.
The following must be programmed in order shown:
