5. Evaluate your drive response.
– If the motor decelerates too slowly, then reduce the ramp-down time.
The minimum ramp-down time that makes sense depends on your particular application.
Depending on the Power Module used, for an excessively short ramp-down time, the
converter either reaches the motor current, or the DC link voltage in the converter
becomes too high.
– Extend the ramp-down time if the motor is braked too quickly or the converter goes into
a fault condition when braking.
6. Repeat steps 1 … 5 until the drive behavior meets the requirements of the machine or plant.
You have set the extended ramp-function generator.

When compared to the extended ramp-function generator, the basic ramp-function generator
has no rounding times.
