2 – TORQUE MODE
ALLOWABLE
RANGE
0 – 100 % Determines the amount of torque applied to the vehicle at a stop with
no throttle input, to emulate the feel of an automatic transmission
0 – 32767
automobile; see Figure 9.
WARNING! When interlock is engaged, creep torque allows
vehicle propulsion if a direction is selected even though no throttle is
applied. Care should be taken when setting up this parameter.
If pedal braking is enabled (see page 47), creep torque is
progressively disabled as brake is applied so as to prevent the motor
from driving into the brakes and thus wasting energy.
Creep Torque and Neutral Taper Speed interact to create the slope
of the torque response as the vehicle approaches zero speed; see
Figure 9. If the vehicle oscillates as it coasts down toward zero speed,
try lowering Creep Torque or increasing Neutral Taper Speed.
25 – 100 % Determines the amount of brake pedal input that will fully cancel the .
creep torque. Amount of cancellation is proportional to the brake input.
8192 – 32767
0.1 – 5.0 s Determines how fast the programmed creep torque builds when
a direction is selected.
100 – 5000
0.1 – 5.0 s Determines how fast the programmed creep torque releases when the
brake is cancelling the creep torque or when the direction switches are
100 – 5000
cleared (neutral).
0 – 100 % Adjusts the throttle take-up from linear (0% setting) to an S curve.
Larger values create softer throttle take-up, in forward and reverse.
0 – 5000
Softening is progressively reduced at higher speeds; see Figure 10.
200 – 6000 rpm Determines the motor speed below which the maximum braking current
is linearly reduced from 100% to 0% at zero speed; see Figure 11.
200 – 6000
Setting the taper speed too low for the braking current will cause
oscillations in the motor as it attempts to brake the vehicle to a stop
on very steep slopes.
Taper speed is applicable only in response to brake pedal input; it
does not affect direction reversal braking or neutral braking.
If the vehicle is in restraint when the brake is pressed, the applied
braking torque is affected by both Brake Taper Speed and Forward (or
Back) Full Restraint Speed. If the vehicle oscillates in this mode, it may
be necessary to increase one or more of these parameters.
0 – 100 % Larger values create a softer reversal from regen braking to drive
when near zero speed. This helps soften the transition when the regen
0 – 3000
and drive current limits are set to different values.
