PARAMETER RANGE DESCRIPTION
Command Analog Left 0 – 5.00 V Denes the command analog wiper voltage required to produce a steer
position command of full left (Steer Command = -100% = Left Stop).
Command Analog Center 0 – 5.00 V Denes the command analog wiper voltage required to produce a steer
position command of center (Steer Command = 0% = 0°).
Command Analog Right
0 – 5.00 V Denes the command analog wiper voltage required to produce a steer
position command of full right (Steer Command = 100% = Right Stop).
Command Analog Fault Min 0 – 5.00 V Sets the minimum threshold for the analog pot input.
If the command analog wiper voltage goes below this threshhold
for 60 ms, a fault is issued.
Command Analog Fault Max
0 – 5.00 V Sets the maximum threshold for the analog pot input.
If the command analog wiper voltage rises above this threshhold
for 60 ms, a fault is issued.

e normalization map takes Command Analog 1 in volts and maps it to Steer
Command in percent. Command Analog Left may be set higher or lower than
Command Analog Right. Command Analog Center must be between Command
Analog Left and Command Analog Right. Assuming Command Analog Left is
less than Command Analog Right, the three points of the normalization map
are dened (from left to right in the diagram above) as:
X = Command Analog Left and Y = -100%
X = Command Analog Center and Y = 0%
X = Command Analog Right and Y = 100%.
