current. (The full rated braking current depends on the controller model; see
specifications in Table E-1.)
The braking current limit is tuned as part of the vehicle performance
adjustment process (Section 5).
M1–M2, BRAKE RATE
The
braking rate
defines the time it takes the controller to increase from 0%
braking output to 100% braking output when a new direction is selected. A
larger value represents a longer time and consequently gentler braking. Faster
braking is achieved by adjusting the braking rate to a smaller value. The braking
rate is adjustable from 0.1 to 3.0 seconds.
M1–M2, DECEL RATE
The
deceleration rate
defines the time it takes the controller to decelerate from
100% output to 0% output. The decel rate determines the vehicle’s braking
characteristic for any reduction in throttle that does not include a request for the
opposite direction. A lower value represents a faster deceleration and thus a
shorter stopping distance. The decel rate is adjustable from 0.1 to 10.0 seconds.
COAST DECEL
The
coast deceleration rate
defines how quickly the controller reduces it output
to zero when the Pick switch is released. This parameter allows adjustment for
different sized vehicles. Lower values represent faster deceleration and thus a
shorter coasting distance. The coast decel rate is adjustable from 0.1 to 10.0
seconds.
TAPER RATE
The
taper rate
determines how quickly the vehicle changes direction when the
opposite direction is selected. Low taper rate values result in fast and abrupt
direction transitions. Higher taper rate values result in slower and smoother
direction transitions. The taper rate is adjustable from 1 to 20.
The taper rate is tuned as part of the vehicle performance adjustment
process (Section 5).
THROTTLE DECEL
The
throttle deceleration rate
parameter adjusts the rate at which the vehicle
transitions to braking when throttle is first reduced. If the throttle decel rate is
set low, deceleration is initiated abruptly. The transition is smoother if the
throttle decel rate is higher; however, setting the throttle decel parameter too
