● 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 steady 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 of 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
● Compared with the "EXPERT" setting:
– Simplified commissioning using predefined
motor data
– Reduced number of parameters
● Standard Drive Control is preset for converters
of frame size A … frame size C
● Fewer parameters compared with the
"EXPERT" setting
● Dynamic Drive Control is preset for converters
of frame size D … frame size J
