MicroController Control System
Systems Operation
Electrical braking permits the lift truck operator to
slow, stop and change the direction of travel
electrically without using the service brake. This
action allows for smooth shuttle operation while
saving wear on the service brakes.
Whether the truck is in plugging or regenerative
mode depends on where the current generated by
the drive motor armature is routed.
Regenerative braking applies when armature
generated current is forced to flow backwards
through the battery. This system has much better
characteristics than previous “plugging only”
systems. The braking energy is used to charge the
battery momentarily, reduce heat build-up in the
drive motor and extend motor brush life.
Plugging applies when armature generated current
takes a more direct path back to armature without
passing through the battery.
Electrical braking begins when the operator selects
a direction opposite the lift truck’s motion, while
