Rudder feedback/tunnel thruster feedback calibration
If a rudder or thruster feedback is available, this must be calibrated. This is required for the
autopilot to know signal for mid-position, port/starboard side and rudder movement range.
 Note:
The graphics below shows the dialog when the rudder is controlled by an SD80. The
confi guration dialog varies with drive device and drive type.
1. Select feedback calibration option in the device confi guration dialog
2. Follow the guided steps through the calibration process
3. Save the settings when completed
Drive test/calibration
When the drives are confi gured and calibrated, the autopilot need to know drive output level
for standstill, polarity for port/stbd movement, the speed/signal- level relationship and max
signal levels allowed. This is learned during the drive test or drive calibration.
1. Select test option in the device confi guration dialog
2. Follow the guided steps through the testing process
3. Save the settings when completed
 Note:
When a rudder feedback signal is set in the confi gure view, the feedback must always
be calibrated before drive test or drive calibration is allowed.
