Controller
The control unit compares the reference value with the measured feedback value and
transmits the error to the controller configurable as PI or PID. The controller calculates
the output signal according to the difference. The output signal is provided as an analog
signal (0...10V / ±10V / 0...20mA / 4...20mA).
With a tacho generator or other source, a 0...10V signal proportional to the line speed can
be fed to the controller. From this signal and the actual output value, the controller then
calculates the actual reel diameter and the pilot control resulting from that. The PI- resp.
PID-values are adustjed dynamically according to the changing reel diameter.
The diameter signal can also be read directly from a distance sensor or other 0...10V
source.
Interface
As standard, the electronic unit supports an RS232 interface. As an option, there is an
additional board with CAN-Bus interface available.
