Setting the extended ramp-function generator
Procedure
1. Enter the highest possible speed setpoint.
2. Switch on the motor.
3. Evaluate your drive response.
– If the motor accelerates too slowly, then reduce the ramp-up time.
– If the motor accelerates too fast, then extend the ramp-up time.
– Increase the initial rounding if the acceleration is jerky.
– In most applications, it is sufficient when the final rounding is set to the same value as the
4. Switch off the motor.

An excessively short ramp-up time means that the motor will reach its current limiting
when accelerating, and will temporarily not be able to follow the speed setpoint. In this
case, the drive exceeds the set time.
