5 — PROGRAMMABLE PARAMETERS: Steer Parameters (for Profiles 1&2)
The Steer menu contains the major parameters that affect the steering and
turning response, speed, and feel of the chair. There are separate Steer menus
for Profile 1 and Profile 2.
Take careful note of the parameters that are affected by the speed limit
(Speed Mode setting) versus those parameters that are affected by the actual
chair speed.
STEER MENU
PARAMETER RANGE DESCRIPTION
Turn Max Speed 1–100 % Turn speed when speed limit is 100%.
Turn Min Speed 1–100 % Turn speed when speed limit is 0%.
Turn Accel High Speed 1–100 % Acceleration rate into a sharper turn when chair is traveling at high
speed.
Turn Accel Low Speed 1–100 % Acceleration rate into a sharper turn when chair is traveling slowly.
Turn Decel High Speed 1–100 % Deceleration rate out of a turn when chair is traveling at high speed.
Turn Decel Low Speed 1–100 % Deceleration rate out of a turn when chair is traveling slowly.
Steer Sensitivity 1–100 % Controls on-center steering gain of the throttle. This parameter
adjusts how much throttle movement is necessary to make small
steering adjustments while the vehicle is traveling at speed.
A value of 1% will make the controller very insensitive, requiring
large movements to make subtle steering adjustments. A value of
100% will give the throttle very high steering gain on-center.
Gate Shape 20–100 % Provides electronic gating of the joystick output command. The turn
command and speed command are both restricted as a function of
joystick position; see Figure 11.
Typically, higher values are appropriate for rear drive, and lower
values for front drive.
Speed Full Turn * 0–100 % These two parameters provide dynamic turn radius control, with the
Speed NoTurn * 0–200 % allowed turning radius being a function of speed; see Figure 12.
The slower the chair is traveling, the tighter it is allowed to turn.
* Patent pending. Speed Full Turn sets the speed below which there is no limit on
the turning radius. For example, with Speed Full Turn set to 20%,
the turn limiting map will begin at 20%; this means that full turning is
available when the chair is traveling below 20% of max speed. Setting
Speed Full Turn to 100% eliminates any limitation on turning.
Speed No Turn sets the speed above which no turning is allowed.
The range for this parameter extends up to 200% of the programmed
forward and reverse max speeds, in order to allow the chair to turn
with little or no limitation even when it is traveling at full speed.
Speed No Turn must be set higher than Speed Full Turn.
