Calculating Slope Compensation Manually
If the center of the machine and center of the implement
positions are 25.4 cm (10 in.) apart on a slope with a
roll angle of 10 degrees, the slope compensation value
should be set to 2.54 cm (1 in.) per degree (25.4 cm (10
in.) of drift divided by 10 degrees of roll angle). If there is
a 25.4 cm (10 in.) difference on a slope with a 5 degree
roll angle, then the value would be 5.1 cm (2 in.)/degree.
Implement Error / Roll Angle = Slope Compensation
NOTE: Recommended adjustment in 0.2 cm (0.05 in.)/deg.
iGuide Sensitivity
iGuide Sensitivity affects how aggressively the system
responds to implement error. This function is similar to
AutoTrac steer sensitivity.
• iGuide Sensitivity allows the system to respond to
implement errors. Higher sensitivity enables iGuide to
quickly react to implement error.
• Too high of a value may cause the system to oscillate
around the intended path. Too low of a value may cause
the implement to react slow when trying to maintain the
implement on the guidance path.
• A starting value of 15 is recommended. Adjust the
sensitivity in small increments until optimal tracking
performance is achieved.
NOTE: Machine steer sensitivity may need to be increased
or decreased to keep the machine on the guidance
path. iGuide is dependent on the machines ability to
track accurately on the intended guidance path.
