When selecting an application class, the inverter assigns the appropriate settings to the motor
control.

– Motor power ratings < 45 kW
– Ramp-up time 0 → rated speed
(depending on the motor power rating):

Dynamic Drive Control
● Typical settling time after a speed change:
< 100 ms
● Typical settling time after a load surge: 200 ms
● Dynamic Drive Control controls and limits the
motor torque
● Torque accuracy that can be achieved: ± 5% for
15 % ... 100 % of the rated speed
● We recommend Dynamic Drive Control for the
following applications:
– Motor power ratings > 11 kW
– For load surges 10 % ... >100 % of the rated
motor torque
● Dynamic Drive Control is necessary for a ramp-
up time 0 → rated speed (dependent on the rated
motor power): < 1 s (0.1 kW) ... < 10 s (132 kW).
