You can select from the three fixed input characteristics shown in figure 4‐1 or you can select a custom characteristic.
Figure 4‐1 shows the relationship between the travel target and travel set point for the fixed input characteristics.
You can specify 21 points on a custom characteristic curve. Each point defines a travel target, in % of ranged travel, for
a corresponding set point, in % of ranged set point. Set point values range from -25.0% to 125%. Before modification,
the custom characteristic is linear. You cannot modify the custom points if the Input Characterization (INPUT_CHAR
[50]) is set to custom.
