The start and end of the acceleration and deceleration ramp can be smoothed
with this parameter. Setting value 0 gives a linear ramp shape which causes
acceleration and deceleration to act immediately to the changes in the refer-
ence signal.
Setting value 0.1…10 seconds for this parameter produces an S-shaped ac-
celeration/deceleration. The acceleration and deceleration times are deter-
mined with parameters 4.2 and 4.3.

These limits correspond to the time required for the output frequency to accel-
erate from the zero frequency to the set maximum frequency, or to decelerate-
from the set maximum frequency to zero frequency.
The user can set two different acceleration/deceleration time sets for one ap-
plication.
The active set can be selected with the selected digital input (par. 5.13)
