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.
Note
Operating a winder, the pilot control is only suitable with a torque controlled drive.
Using a speed controlled drive, pilot control won’t work as expected. (This notice
doesn’t apply if a brake is operated.)
Transmission of diameter signal
To transmit the actual reel diameter to the electronic unit, an analog signal 0...10V
(from a distance sensor or other source) is fed to the analog input (terminals

and

; refer to wiring diagram)
Diameter adjustment
To get the electronic unit knowing the actual reel diameter, the distance signal must be
assigned to a diameter range:
•
Set parameter
Pilot control
to
Yes.
•
Insert reel with small diameter to get a signal according to the small diameter from
the distance sensor, or set PLC diameter signal to a small value.
•
When in the main operating menu, press

signal.
