3 — PROGRAMMABLE PARAMETERS: Braking Parameters
DECEL MAX SPD
The maximum-speed forward deceleration rate determines the time it takes
the controller to decelerate from its present output to zero when the throttle is
released to neutral during forward travel with the speed limit pot in its maxi
-
mum speed position. Larger values represent a longer deceleration time and
gentler stops. Smaller values will reduce the stopping distance required. The
maximum-speed deceleration rate should be set at a value that will ensure the
vehicle stops within a safe distance when traveling at full speed. The maximum-
speed deceleration rate is adjustable from 0.2 to 4.0 seconds. Deceleration rates
under 0.5 second provide abrupt stops and should only be used under special
circumstances.
DECEL MIN SPD
The minimum-speed forward deceleration rate defines the time it takes
the controller to decelerate from its present output to zero when the throttle
is released to neutral during forward travel with the speed limit pot in its
minimum speed position. Larger values represent a longer deceleration time
and gentler stops. Smaller values will reduce the stopping distance required.
The minimum-speed deceleration rate is adjustable from 0.2 to 8.0 seconds.
Deceleration rates under 0.5 second provide abrupt stops and should only be
used under special circumstances.
E STOP
The emergency stop deceleration rate defines the time it takes the vehicle
to stop when a reverse throttle command >80% is given while the vehicle is
moving forward. This gives the operator a way to stop more quickly when
unexpected conditions arise.
When the E Stop feature is invoked the E Stop deceleration rate becomes
the new forward deceleration rate. Therefore it makes sense to set it to a value
lower (faster stop) than the fastest forward deceleration rate (DECEL MAX SPEED).
The E Stop deceleration rate is adjustable from 0.2 to 4.0 seconds.
REV DECEL MAX
The maximum-speed reverse deceleration rate defines the time it takes the
controller to decelerate from its present output to zero when the throttle is re
-
leased to neutral during reverse travel with the speed limit pot in its maximum
speed position. Larger values represent a longer deceleration time and gentler
stops. Smaller values will reduce the stopping distance required. The maxi-
mum-speed reverse deceleration rate should be set at a value that will ensure
the vehicle stops within a safe distance when traveling in reverse at full speed.
The maximum-speed deceleration rate is adjustable from 0.2 to 4.0 seconds.
