5. DESCRIPTION OF THE FUNCTIONS
(5) Regenerative control
(a) Switchback regeneration
• Regenerative braking occurs when the F/R lever is switched from forward to reverse or vice versa
while the accelerator pedal is pressed.
<Activation conditions>
See the table below.
(b) Brake OFF regeneration
• Regenerative braking occurs when the brake switch is turned OFF.
< Activation conditions>
See the table below.
(c) Accelerator neutral regeneration (accelerator OFF regeneration)
• Regenerative braking occurs when the accelerator lever is moved to the neutral position while the
truck is traveling.
< Activation conditions>
See the table below.

*1: Driving with output limit: This refers to inching control. Limited to 80% of the maximum torque (Excessive Travel inching).
*2: Driving in slope mode: When a truck driving down a slope exceeds the speed that should normally be obtained by a given amount of accelerator pedal
pressure, the power output will be limited in order to maintain the speed that corresponds to that accelerator pedal effort.
(6) Output duty factor reduction when the rear wheels are at the maximum steering angle
(Excluding trucks with an Orbitrol steering system)
<Activation conditions>
• The rear wheels are within 5 degrees of the maximum steering angle.
<Control applied>
• Limits the output duty factor to 10%.
<Deactivation conditions>
• When the torque sensor voltage indicates that the wheels are in neutral (the straight-ahead position).
