Throttle Ramp Shaping
Throttle ramp shaping affects the PWM output response relative to the throttle
position. The more ramp shaping the throttle circuitry has, the more control the
operator has over low speed. Therefore, there is a smaller change in output duty
cycle relative to a specific amount of change in throttle output. An example set
of throttle ramp shaping responses is shown in Figure 16. The various ramp
shaping options shown in the figure are not all available on all controllers. Call
your local dealer or Curtis office for details.
