4.1
Functional Description
The sensors measure the position of the web edge and send this information as an analog
signal to the electronic control unit. The control unit compares the position feedback signal
with the reference. If the difference is higher than a parametrized value (dead band), the
steering device is adjusted to bring the web into the right position.
If the sensors are equipped with linear units, the control unit automatically lets them follow the
edge. The actual position of the sensors on the linear unit is taken into calculation for the
actual web position.
4.2
Steering device
The steering device adjusts the web position laterally. Its width is depending on the web
width. Any steering device can be used if it can handle the signal for an FMS steering frame
with DC motor drive:
−
FMS steering frame with DC drive
−
any actuator with analog input ±10V / 0...10V / 0...20mA / 4...20mA
−
Optionally: ±300mA / ±10V for a moving coil controller (hydraulic actuator)
