Fine tuning the acceleration and deceleration rates
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.
j. For additional soening of the deceleration response, you could adjust the So Stop Speed
parameter to a larger value (see page 16).
k. In rare cases, it may be desirable to adjust the rottle Map parameter. is parameter can
be used, for example, to extend the throttle’s gentle acceleration range to further enhance
maneuverability in confined areas. See page 19 for a description of rottle Map.
Key Off deceleration rate
e Key O Decel parameter sets the decel rate that will be used to slow the vehicle at key-o or in
the event of a major fault.
l. Drive fast and turn the key o. e deceleration you experience is determined by Key O Decel.
m. Adjust the Key O Decel value to produce the desirable “feel” for emergency stops: typically as
fast as possible without making the vehicle unstable.
n. Note that Key Off Decel should always be set faster than (or equal to) the fastest forward
deceleration rate, Decel High Speed.
E Stop deceleration rate
e E Stop Decel parameter sets the decel rate that will be used when the vehicle is moving forward
and the throttle makes a fast transition through neutral to a >80% reverse throttle request. is
provides a way to stop more quickly when unexpected conditions arise.
o. Drive fast and throw the throttle into >80% reverse. The deceleration you experience is
determined by E Stop Decel.
p. Adjust the E Stop Decel value to produce the desirable “feel” for emergency reverse stops:
typically as fast as possible without making the vehicle unstable.
q. Note that the E Stop Decel rate should always be set faster than (or equal to) the fastest forward
deceleration rate, Decel High Speed.
r. e E Stop Pause parameter can be used to create a pause aer the vehicle has come to an
emergency stop, thus giving the operator a chance to return the throttle to neutral before the
vehicle starts to travel backwards. Adjust the E Stop Pause value to provide the appropriate pause.
A longer pause might be preferred for a vehicle that will be mainly used indoors, whereas for a
vehicle that will be used outdoors a faster initiation of reverse travel might be desirable.
