In Figure 16, the creep speed is increased to 10% and the maximum speed
is left at 100%, resulting in a controller output range of 90%. With these speed
settings, a 50% throttle map will result in 55% output (45% + 10%) at half
throttle.

Throttle maps for
controller with maximum
speed set at 100% and
creep speed set at 10%.

Throttle maps for
controller with maximum
speed set at 90% and
creep speed set at 0%.
In Figure 17, the maximum speed is decreased to 90% and the creep speed
is left at 0%; again, the controller output range is 90%. With these speed
settings, a 50% throttle map will result in 45% output at half throttle.

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
