4.4.2 Drive motor brake (travel brake)
The truck is braked primarily by means of regenerative braking using
the drive motor. Motor braking can be obtained in three different ways.
These are:
• Releasing the accelerator when the truck is in motion
• Changing the direction of travel using the travel direction selector, at
the same time as depressing the accelerator
• Depressing the brake pedal
Accelerator released
The regenerative motor brake is automatically engaged when the
accelerator is released. The brake force can be adjusted using an oper
-
ator parameter - see section "2 – Parameters".
The motor brake force is regulated to allow for the current speed and
the extent to which the accelerator is released. This works as follows:
• Braking at a high speed, with the accelerator fully released, results
in high brake force.
• Braking at a low speed, with the accelerator fully released, results in
lower brake force.
• Braking at a high speed, with the accelerator half released, results in
medium brake force.
Changing the direction of travel
When the direction of travel is changed during operation, the motor
brakes the truck so that the direction of travel can be changed. Here
motor braking is regulated by the position of the accelerator - the further
the pedal is depressed, the greater the force involved in braking.
The brake force for a change in direction of travel can be adjusted using
a service parameter - see section "2 –
Parameters".
