5 — INITIAL SETUP
Tuning the Throttle Deadband
3-a. Make sure the interlock switch is open, and turn on the keyswitch.
3-b. Observe the Monitor > Inputs > Throttle Input parameter; you will
need to reference the value displayed here.
3-c. Scroll down to the Forward Input parameter; the display should
indicate that the forward switch is Off.
3-d. 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.
3-e. Without moving the throttle, read the value shown for the Throttle
Input parameter. This value should be zero. If the Throttle Input value is zero,
proceed to step 3-f. If it is greater than zero, the Throttle Deadband must be
increased (Program > Vehicle > Throttle > Throttle Deadband). Repeat steps 3-d
and 3-e until the Throttle Input monitor value is zero at the forward direction
engagement point.
3-f. While observing the Throttle Input monitor value, continue to
rotate the throttle past the forward switch engagement point. Note where the
Throttle Input value begins to increase, indicating that the controller would
begin to supply drive power to the motor (if the interlock were closed). If the
throttle had to be rotated further than desired before the Throttle Input value
began to increase, the Throttle Deadband must be
decreased and the procedure
repeated from step 3-d. If the amount of rotation between the point at which
the forward switch is engaged and the Throttle Input value begins to increase
is acceptable, the Throttle Deadband is properly tuned.
3-g. If a bidirectional (wigwag) throttle assembly is being used, the
procedure should be repeated for the reverse direction. The Throttle Dead
-
band value should be selected such that the throttle operates correctly in both
forward and reverse.
Tuning the Throttle Max
3-h. Rotate the throttle forward to its maximum speed position and
observe the Throttle Input value. This value should be 100%. If it is less than
100%, the Throttle Max value must be
decreased to attain full controller out-
put at the maximum throttle position Program > Vehicle > Throttle > Throttle
Max). Repeat until the Throttle Input value is 100%.
3-i. Now that the full throttle position results in a 100% value for
Throttle %, slowly reduce throttle until the Throttle % value drops below 100%
and note the throttle position. This represents the extra range of motion allowed
by the throttle mechanism. If this range is large, you may wish to decrease it
by increasing the Throttle Max value. This will provide a larger active throttle
range and more vehicle control. Increase Throttle Max and repeat the test until
an appropriate amount of extra range is attained.
3-j. If a wigwag throttle is being used, repeat the procedure for the
reverse direction. The Throttle Max
value should be selected such that the
throttle operates correctly in both forward and reverse.
