The programmer displays hydraulic Throttle Max as a percentage of the
throttle’s active voltage range. The nominal voltage range depends on the
throttle type selected. See Table 1 (page 12) for the characteristics of your
selected throttle type. The hydraulic Throttle Max parameter can be adjusted
from 100% to 60%, in 1% increments.
HYD THRTL MAP
The hydraulic throttle map parameter modifies the response to a throttle
input. This parameter determines the controller output for a given amount of
applied throttle. Setting the throttle map parameter at 50% provides a linear
output response to throttle position. Values below 50% reduce the controller
output at low throttle requests, providing enhanced slow speed Lift control.
Values above 50% give the Lift a faster, jumpier feel at low throttle requests.
The throttle map can be programmed between 20% and 80%. The
number refers to the controller output at half throttle, as a percentage of the
throttle’s full active range. The throttle’s active range is the voltage or resistance
between the 0% output point (throttle deadband) and the 100% output point
(throttle max). For example, if the maximum pump speed is set at 100%, a
throttle map setting of 50% will give 50% output at half throttle. The 50%
setting corresponds to a linear response. Six throttle map profiles (20, 30, 40,
50, 60, and 80%) are shown as examples in Figure 23, with the maximum
pump speed set at 100%.

CONTROLLER OUTPUT (percent PWM)
Reducing the maximum pump speed will limit the controller’s output
range. Throttle map profiles with the maximum pump speed reduced from
100% to 80% are shown in Figure 245. The throttle map is always a percentage
of the controller’s output range. So, in these examples, the throttle map is a
percentage of the 0–80% output range; a 40% throttle map setting will give
32% output at half throttle (40% of 80% = 32%). Controller output will begin
