General Maintenance and Diagnostic Data

Speed Steering Reduction

This optional parameter defines the speed reduction
that the motor will target from its current level once the
speed reduction sensor changes from ON to OFF. If
parameter is set at 75%, and the truck was been
driven at 1000 RPM, upon steering the motor will
decelerate to 750 RPM.

Traction Steering Decel Ramp

This optional parameter will determine the time that it
will take the motor to decelerate from current speed to
NOTE: IN THIS EXAMPLE, HS = 70%, LS = 30%, TYPICAL MAX SPEED = 5000 RPM

Response-Full Accel Rate LS

This parameter sets the rate (in seconds) at which the
speed command increases when full throttle is applied
at low vehicle speeds.

Response-Low Accel Rate

This parameter sets the rate (in seconds) at which the
speed command increases when a small amount of
throttle is applied. This rate is typically adjusted to
affect low speed maneuverability.

Response-Neutral Decel Rate HS

This parameter sets the rate (in seconds) that is used
to slow down the vehicle when the throttle is released
to neutral at high vehicle speeds.

speed determined by Speed Steering Reduction
parameter. Larger values represent slower response.

Response-Full Accel Rate HS

This parameter will set the rate (in seconds) at which
the speed command increases when full throttle is
applied at high vehicle speeds. Larger values
represent slower response. See Figure 9030-03-2 for
relationship between Full Accel Rate HS, Full Accel
Rate LS, and Low Accel Rate.

Response-Neutral Decel Rate LS

This parameter sets the rate (in seconds) that is used
to slow down the vehicle when the throttle is released
to neutral at slow vehicle speeds.

Fine Tuning-Partial Decel Rate

This parameter sets the rate (in seconds) that is used
to slow down the vehicle when the throttle is reduced
without being released to neutral. Larger values
represent slower response.

Fine Tuning-HS (High Speed)

This parameter sets the percentage of the Typical Max
Speed above which the "HS" parameters will be used.
