Fine Tuning-LS (Low Speed)

This parameter sets the percentage of the Typical Max
Speed below which the “LS” parameters will be used.

Fine Tuning-Reversal Soften

This parameter, when set to larger values create a
softer reversal from regen braking to drive when near
zero speed. The parameter will soften the transition
when the regen and drive current limits are set to
different values.

Fine Tuning-Max Speed Accel

In some applications, the Max Speed value is changed
frequently over the CANbus. The Max Speed Accel
parameter controls the rate at which the maximum
speed setpoint is allowed to change when the value of
Max Speed is raised. The rate set by this parameter is
the time to ramp from 0 RPM to Typical Max Speed
RPM. If Max Speed is raised from 1000 RPM to 3000
RPM, the Typical Max Speed is 3200 RPM and the
rate is 10.0 seconds, it will take 10.0 * (3000–1000) /
3200 = 6.25 seconds to ramp from 1000 RPM to 3000
RPM.

Fine Tuning-Max Speed Decel

This parameter is like the Max Speed Accel parameter,
except that it controls the rate at which the maximum
speed setpoint is allowed to change when the value of
Max Speed is lowered. If one changes Max Speed
from 300 RPM to 1500 RPM, the Typical Max Speed is
3200 RPM, and the rate is 5.0 seconds, it will take 5.0
* (3000–1500) / 3200 = 2.34 seconds to ramp from
3000 RPM to 1500 RPM.

Interlock Timeout

This parameter will set the time for which the truck can
remain at idle condition while the arm is in operational
region B. See Figure 9030-03-3.

Mode (1 through 3) -Max Speed

This parameter defines the maximum requested motor
rpm at full throttle.

RPM = V

Desired

* 936

Example:

RPM = 2.5MPH * 936 = 2340 rpm

Mode (1 through 3) -Max Accel

This parameter sets the rate (in seconds) at which the
motor speed command increases when throttle is
applied. Larger values represent slower response.

Mode (1 through 3) -Walk Accel

This parameter sets the rate (in seconds) at which the
motor speed command increases when throttle is
applied, when truck is not in turtle mode. Larger values
represent slower response.

Mode (1 through 3) -Max Decel

This parameter sets the rate (in seconds) that is used
to slow down the vehicle when the throttle is reduced.
Larger values represent slower response.

Mode (1 through 3) -Neutral Braking

This parameter adjusts how neutral braking occurs
progressively when the throttle is reduced toward the
neutral position or when no direction is selected.

Mode (1 through 3) -Max Braking

This parameter sets the rate (in seconds) at which the
vehicle slows down when full brake is applied or when
throttle is applied in the opposite direction.

Max Speed TM2

This parameter defines the maximum requested motor
rpm at full throttle when the truck is driven in Advance
Turtle mode in region B. See Figure 9030-03-3.

Max Accel TM2

This parameter sets the rate (in seconds) at which the
motor speed command increases when throttle is
applied. This parameter is applicable only while the
truck is driven while in Advance Turtle Mode. Larger
values represent slower response.

Max Decel TM2

This parameter sets the rate (in seconds) that is used
to slow down the vehicle when the throttle is reduced.
Larger values represent slower response.

Neutral Braking TM2

Neutral braking occurs progressively when the throttle
is reduced toward the neutral position or when no
direction is selected. This This parameter is applicable
only while the truck is driven while in Advance Turtle
Mode.

Max Braking TM2

This parameter sets the rate (in seconds) at which the
vehicle slows down when full brake is applied or when
throttle is applied in the opposite direction. This
parameter is applicable only while the truck is driven
while in Advance Turtle Mode.
