3 — PROGRAMMABLE PARAMETERS:
Acceleration Parameters
REV ACCEL MAX
The
maximum-speed reverse acceleration rate
defines the time it takes the
controller to accelerate from zero to 100% output while traveling in reverse at
full throttle with the speed limit pot in its maximum speed position. Larger
values represent a longer acceleration time and gentler starts, while smaller values
represent faster acceleration. The maximum-speed reverse acceleration rate is
adjustable from 0.2 to 8.0 seconds. Acceleration rates under 0.5 second provide
abrupt acceleration and should only be used under special circumstances.
The maximum-speed and minimum-speed reverse acceleration rates are
scaled linearly to provide appropriate response throughout the speed limit pot’s
range.
REV ACCEL MIN
The
minimum-speed reverse acceleration rate
defines the time it takes the
controller to accelerate from zero to 100% output while traveling in reverse at
full throttle with the speed limit pot in its minimum speed position. Larger
values represent a longer acceleration time and gentler starts, while smaller values
represent faster acceleration. The minimum-speed reverse acceleration rate is
adjustable from 0.2 to 8.0 seconds. Acceleration rates under 0.5 second provide
abrupt acceleration and should only be used under special circumstances.
GEAR SOFTEN
The
gear soften
feature allows smooth pickup of gear slack in the transmission
when torque is reversed; it affects all accelerations except those from zero speed.
The effect of this feature is most noticeable when reapplying the throttle from
neutral after decelerating from high speed but before coming to a stop. (See
soft start parameter, below, for softening torque endpoints for accelerations
from a complete stop.)
The gear soften parameter is adjustable from 0% to 100%, with 100%
providing a great deal of softening and 0% eliminating the feature. The trade-off
in increasing the gear soften value is that acceleration response may be slowed
somewhat, especially at higher values.
SOFT START
The
soft start
feature allows softened torque endpoints for forward/reverse
accelerations from a complete stop. When accelerating from a stop, some users
prefer the softened gear slack transitions this parameter can provide, while others
prefer the vehicle to respond instantly.
The soft start parameter is adjustable from 0% to 100%, with 100%
providing a great deal of softening and 0% eliminating the feature. The trade-
off in increasing the soft start value is that acceleration response may be slowed
somewhat, especially at higher values.
