3 — PROGRAMMABLE PARAMETERS: Throttle Parameters
THROTTLE MENU
ALLOWABLE
PARAMETER RANGE DESCRIPTION
Throttle Type 1 – 5 These E and SE controllers accept a variety of throttle inputs.
Throttle_Type 1 – 5 The throttle type parameter can be programmed as follows:
0x3000 0x00
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.
Forward Deadband
 0.00–5.00V Denesthewipervoltageatthethrottledeadbandthreshold.Increasing
Forward_Deadband 0 – 32767 the throttle deadband setting will increase the neutral range. This
0x3001 0x00 parameter is especially useful with throttle assemblies that do not reliably
returntoawell-denedneutralpoint,becauseitallowsthedeadbandto
bedenedwideenoughtoensurethatthecontrollergoesintoneutral
when the throttle mechanism is released.
Forward Map
 0–100% Modiesthevehicle’sresponsetothethrottleinput.Settingthethrottle
Forward_Map 0 – 32767 map at 50% provides a linear output response to throttle position. Values
0x3002 0x00 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).
Forward Max
 0.00–5.00V Denesthewipervoltagerequiredtoproduce100%controlleroutput.
Forward_Max 0 – 32767 Decreasing the throttle max setting reduces the wiper voltage and
0x3003 0x00 therefore the full stroke necessary to produce full controller output.
This parameter allows reduced-range throttle assemblies to be
accommodated.
Forward Offset
 0–100% Denestheinitialcontrolleroutputgeneratedwhenthethrottleisrst
Forward_Offset 0 – 32767 rotated out of the neutral deadband. For most vehicles, a setting of 0
0x3004 0x00 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, Oset — condition the raw throttle voltage into a single %
throttle command, as shown in Figure 14.
