The accleration and deceleration times determine the time required by the drive to
follow a setpoint change.
D The acceleration and deceleration times refer to a change of the field frequency
from 0 Hz to the max. field frequency set under C011.
D Calculate the times T

Under unfavourable operating conditions, too short acceleration and deceleration
times can lead to the deactivation of the controller under overload with the indication
of TRIP OC5. In these events, the acceleration and deceleration times should be set
short enough so that the drive can follow the speed profile without reaching I
controller.
The slope can be set between 0.095Hz/s and 780Hz/s.
