Curtis 1228 Manual, Rev. F
drive in a confined area such as an office, where low speed maneuverability
is crucial. Depending on how you liked the acceleration you experienced
while driving in reverse, increase or decrease the
REV ACCEL MIN value from
its default setting. Smaller values provide faster response. Continue testing
and adjusting this value until you are satisfied with the vehicle’s low speed
reverse acceleration behavior.
6-f. Now adjust REV DECEL MIN, the low speed reverse deceleration characteristic.
Leaving the speed limit pot in its minimum speed position, drive in reverse
at full throttle and then release the throttle to neutral. Depending on how
you liked the deceleration you experienced, increase or decrease the
REV DE-
CEL MIN
value from its default setting. Smaller values provide faster response.
Continue testing and adjusting this value until you are satisfied with the
vehicle’s low speed reverse deceleration behavior.
6-g. Next, set the REV ACCEL MAX. Select Mode 2 and set the speed limit pot to its
maximum speed position. Driving in reverse, apply full throttle. Depend
-
ing on how you liked the reverse acceleration you experienced, increase or
decrease the
REV ACCEL MAX value from its default setting. Smaller values
provide faster response. Continue testing and adjusting this value until you
are satisfied with the vehicle’s high speed reverse acceleration.
6-h. Leaving the speed limit pot in its maximum speed position, drive in reverse
at full throttle and then release the throttle to neutral. Depending on how
you liked the deceleration you experienced, increase or decrease the
REV DECEL
MAX value from its default setting. Smaller values provide faster response.
Continue testing and adjusting this value until you are satisfied with the
vehicle’s high speed reverse deceleration behavior.
Fine tuning the acceleration and deceleration rates
6-i. Drive around in both Mode 1 and Mode 2, while varying the position of
the throttle and the speed limit pot. In most cases, setting the acceleration
and deceleration rates as described in Steps 6-a through 6-h will provide
good performance throughout. However, you may want to make further
adjustments to them.
6-j. In rare cases, it may be desirable to adjust the RAMP SHAPE parameter. This
parameter can be used, for example, to extend the throttle’s gentle accelera
-
tion range to further enhance maneuverability in confined areas. See page
26 for a detailed description of the ramp shape options.
Emergency stop deceleration rate
The E STOP function is invoked when the vehicle is moving forward and the
throttle makes a fast transition through neutral to a >80% reverse throttle re
-
quest. This provides a way to stop more quickly when unexpected conditions
arise. When the
E STOP function engages, its programmed value becomes the new
forward deceleration rate, replacing the regular forward deceleration rate.
6-k. Drive fast and suddenly release the throttle. You will experience the decel-
eration behavior determined by the forward deceleration rate.
