of acceleration/deceleration times defined by
parameters 28.72…28.75.

20.000 s / real32Defines acceleration time 1 as the time required for the
frequency to change from zero to the frequency defined
by parameter 46.2 Frequency scaling (not to parameter
30.14 Maximum frequency).
If the reference increases faster than the set
acceleration rate, the motor will follow the acceleration
rate.
If the reference increases slower than the set
acceleration rate, the motor frequency will follow the
reference.
If the acceleration time is set too short, the drive will
automatically prolong the acceleration in order not to
exceed the drive torque limits.
