2.5 OPERATIONAL FEATURES
- Speed Control .
- Optimum sensitivity at low speeds.
- Speed Reductions in both the directions. Levels can be set using Console.
- Regenerative Braking based on deceleration ramps, in every condition.
- Three different modes of Braking : Release Braking, Inversion Braking, Speed Limit
Braking.
- Speed Control during descent : the motor speed follows the accelerator. The chop-
per automatically brakes if the motor speed overcomes the accelerator set point.
This provides optimum performance on a gradient.
- Starts on a Ramp without roll back, even without an electric brake.
- Programmable Anti Roll Back : When the Key Switch is closed, if the motor is rotat-
ing, the chopper controls the speed and automatically brakes and keeps the motor at
a very low speed during descent on a gradient. This is a very useful safety feature
and is not driver dependent.
