Response Parameters
2 – TORQUE MODE
ALLOWABLE
RANGE
0.1 – 30.0 s Sets the rate (in seconds) at which the motor torque increases to full
when full throttle is applied. Larger values represent slower response.
100 – 30000
0.1 – 2.0 s Determines how quickly deceleration will be initiated when the throttle
is released while the vehicle is still accelerating. If the release rate
100 – 2000
is fast (i.e., set to a low value), the transition is initiated abruptly.
The transition is smoother if the release rate is set to a higher value
(slower transition); however, setting the rate too high can cause the
vehicle to feel uncontrollable when the throttle is released, as it will
continue to drive for a short time.
0.1 – 5.0 s Adjusts the rate (in seconds) at which braking torque builds as the
vehicle transitions from drive to braking when direction is reversed,
100 – 5000
the brake pedal is applied, or neutral braking begins. Lower values
represent faster times and therefore faster braking; gentler braking is
achieved by setting the braking rate to a higher value.
0.1 – 2.0 s Adjusts the rate (in seconds) at which braking torque releases as
as the vehicle transitions from braking to drive.
100 – 2000
0 – 100 % Neutral braking occurs progressively when the throttle is reduced
toward the neutral position or when no direction is selected. The
0 – 32767
neutral braking parameter is adjustable from 0 to 100% of the regen
current limit (see Current Limits menu, page 41).
200 – 6000 rpm Determines the motor speed below which neutral braking current
is adjusted when throttle is reduced; see Figure 9.
200 – 6000
The neutral braking current is linearly reduced from Neutral
Braking * Regen Current Limit at the Neutral Taper Speed to the
Creep Torque current at zero rpm motor speed.
Note: Setting the taper speed too low may cause oscillations in
the motor.
100 – 32000 rpm Sets the speed point at which the full regen current will be applied to
restrain the vehicle from rolling forward. Although this speed is never
100 – 32000
actually reached, it does set the slope of the restraint strength and
can be thought of as a gain; see Figure 9. Setting this parameter too
low can cause oscillations.
100 – 32000 rpm Sets the speed point at which the full regen current will be applied to
restrain the vehicle from rolling in reverse (backward). Although this
100 – 32000
speed is never actually reached, it does set the slope of the restraint
strength and can be thought of as a gain; see Figure 9. Setting this
parameter too low can cause oscillations.
