THROTTLE INPUT (percent of active range)
The Throttle Map operates within the window established by the Creep
Speed, Max Speed, Throttle Deadband, and Throttle Max parameters, as shown
in Figure 18. Creep Speed and Max Speed define the controller's output range,
while Throttle Deadband and Throttle Max define the throttle's active range.
These four parameters, together with the Throttle Map, determine the controller's
output response to throttle demand.
