ALLOWABLE
PARAMETER RANGE DESCRIPTION
Creep Torque 0 – 100 % Determines the amount of torque applied to the vehicle at a stop with
Creep_Torque_TrqM 0 – 32767 no throttle input, to emulate the feel of an automatic transmission
0x3071 0x00 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

Figure9.Ifthevehicleoscillatesasitcoastsdowntowardzerospeed,
try lowering Creep Torque or increasing Neutral Taper Speed.
Brake Full Creep Cancel
25 – 100 % Determines the amount of brake pedal input that will fully cancel the .
Brake_Full_Creep_Cancel_TrqM 8192 – 32767 creep torque. Amount of cancellation is proportional to the brake input.
0x3837 0x00
Creep Build Rate 0.1 – 5.0 s Determines how fast the programmed creep torque builds when
Creep_Build_Rate_TrqM 100 – 5000 a direction is selected.
0x3832 0x00
Creep Release Rate
0.1 – 5.0 s Determines how fast the programmed creep torque releases when the
Creep_Release_Rate_TrqM 100 – 5000 brake is cancelling the creep torque or when the direction switches are
0x3833 0x00 cleared (neutral).
Gear Soften 0 – 100 % Adjusts the throttle take-up from linear (0% setting) to an S curve.
Gear_Soften_TrqM 0 – 5000 Larger values create softer throttle take-up, in forward and reverse.
0x302A 0x00 Softening is progressively reduced at higher speeds; see Figure 10.
Brake Taper Speed 200 – 6000 rpm Determines the motor speed below which the maximum braking current
Brake_Taper_Speed_TrqM 200 – 6000 islinearlyreducedfrom100%to0%atzerospeed;seeFigure11.
0x300F 0x00 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.
Reversal Soften
0 – 100 % Larger values create a softer reversal from regen braking to drive
Reversal_Soften 0 – 3000 whennearzerospeed.Thishelpssoftenthetransitionwhentheregen
0x3074 0x00 and drive current limits are set to different values.
