Throttle Parameters

THROTTLE MENU

RANGE
1 – 5 These E and SE controllers accept a variety of throttle inputs.
The throttle type parameter can be programmed as follows:
1 – 5
1 2-wire rheostat, 5kΩ–0 input
2 single-ended 3-wire 1kΩ–10kΩ potentiometer,
or 0–5V voltage source
3 2-wire rheostat, 0–5kΩ input
4 wigwag 3-wire 1kΩ–10kΩ potentiometer,
or 0–5V voltage source
5 VCL input (VCL_Throttle)
Note: Do not change this parameter while the controller is powering the
motor. Any time this parameter is changed a Parameter Change Fault
(fault code 49) is set and must be cleared by cycling power; this protects
the controller and the operator.
Defines the wiper voltage at the throttle deadband threshold. Increasing
the throttle deadband setting will increase the neutral range. This
parameter is especially useful with throttle assemblies that do not reliably
return to a well-defined neutral point, because it allows the deadband to
be defined wide enough to ensure that the controller goes into neutral
when the throttle mechanism is released.
Modifies the vehicle's response to the throttle input. Setting the throttle
map at 50% provides a linear output response to throttle position. Values
below 50% reduce the controller output at low throttle settings, providing
enhanced slow speed maneuverability. Values above 50% give the vehicle
a faster, more responsive feel at low throttle settings.
The map value is the percentage of controller output at half throttle
((deadband + max)/2).
Defines the wiper voltage required to produce 100% controller output.
Decreasing the throttle max setting reduces the wiper voltage and
therefore the full stroke necessary to produce full controller output.
This parameter allows reduced-range throttle assemblies to be
accommodated.
Defines the initial controller output generated when the throttle is first
rotated out of the neutral deadband. For most vehicles, a setting of 0
is appropriate. For heavy vehicles, however, increasing the offset may
improve controllability by reducing the amount of throttle required to start
the vehicle moving.
Note: All four throttle adjustment parameters — Deadband, Map,
Max, Offset — condition the raw throttle voltage into a single %
throttle command, as shown in Figure 14.
