When selecting an application class, the inverter assigns the motor control with the appropriate
default settings:
● Standard Drive Control (Page 162)
● Dynamic Drive Control (Page 164)
● Start quick commissioning and select the application class (Page 154)
Depending on the particular Power Module, the inverter skips selecting the application
class. If the BOP-2 does not display step DRV APPL, then continue commissioning as
described under "Expert".

● Standard Drive Control is suitable for the
following requirements:
– Motor power ratings < 45 kW
– Ramp-up time 0 → rated speed
(depending on the motor power rating):
1 s (0.1 kW) … 10 s (45 kW)
– Applications with increasing load torque
without load surges
● Standard Drive Control is insensitive with
respect to imprecise setting of the motor data
● 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).
