PARAMETER RANGE DESCRIPTION
P1–P6 Input -100.0 – 100.0 % These six parameters individually dene the steer command input
(in %) for the P1, P2, P3, P4, P5, and P6 Inputs.
Left Stop (deg)
-120.0° – 0.0° These eight parameters dene the steer command output (in degrees)
of the steer command map.

The map in this example is set up to provide a deadband
in the center (points D and E) and less sensitivity at the
ends (between A and B, and between G and H).

The steer command map is shaped by points A – H.
A command map is used in the input command signal ow to compensate for
steering geometry dierences between vehicles (steered wheel on the left side,
middle, or right side).
e command map menu contains 14 parameters dening an 8-point
map that modies the steer command input. e rst point (Left Stop (deg))
always denes the steer command input of -100% and the last point (Right
Stop deg)) always denes the steer command input of 100%.
Although any map shape can be set up, it is recommended that the map al-
ways be set so that a Steer Command of zero % equals a Steer Command
(deg) of zero.
