5 — VEHICLE PERFORMANCE ADJUSTMENT
1 -A Tuning the Throttle Deadband
STEP
1. Jack the vehicle wheels up off the ground so that they spin
freely.
STEP
2. Plug the programmer into the controller and turn on the key-
switch and interlock switch (if used).
STEP
3. Select the Monitor Menu. The Throttle % field should be visible
at the top of the display. You will need to reference the value
displayed here. For convenience, set a bookmark here so you can
return easily to read the Throttle % value.
STEP
4. Scroll down until the Forward Input field is visible. The display
should indicate that the forward switch is Off.
STEP
5. Slowly rotate the throttle forward until the display indicates
that the forward switch is On. Use care with this step as it is
important to identify the threshold throttle position at which
the forward switch is engaged and the controller recognizes the
forward command.
STEP
6. Without moving the throttle, return to the Throttle % field and
read the value shown. This value should be zero. If the Throttle
% value is zero, proceed to Step 7. If it is greater than zero, the
Throttle Deadband parameter must be increased (go to the Pro-
gram menu) and the procedure repeated from Step 5 until the
Throttle % is zero at the forward direction engagement point.
Setting a second bookmark at the Throttle Deadband parameter
will allow you to toggle back and forth easily between the pa-
rameter and the Throttle % field.
STEP
7. While observing the Throttle % value in the programmer’s Test/
Monitor Menu, continue to rotate the throttle past the forward
switch engagement point. Note where the Throttle % value begins
to increase, indicating that the controller has begun to supply
drive power to the motor. If the throttle had to be rotated fur-
ther than desired before the Throttle % value began to increase,
the Throttle Deadband parameter value must be decreased and
the procedure repeated from Step 5. If the amount of rotation
between the point at which the forward switch is engaged and
the Throttle % value begins to increase is acceptable, the Throttle
Deadband is properly tuned.
STEP
8. If a bidirectional (wigwag) throttle assembly is being used, the
procedure should be repeated for the reverse direction. The
Throttle Deadband value should be selected such that the throttle
operates correctly in both forward and reverse.
