● "Standard Drive Control" is suitable to
address 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).

Commissioning
● Unlike "Dynamic Drive Control," no speed
controller needs to be set
● When compared to "Expert":
– Simplified commissioning using
predefined motor data
– Reduced number of parameters
● "Standard Drive Control" is preset for Power
Modules, frame size A … frame size C
● Reduced amount of parameters when
compared to "Expert"
● "Dynamic Drive Control" is preset for Power
Modules frame size D … frame size JX
Commissioning
5.5 Quick commissioning with a PC
Converter with the CU230P-2 Control Units
