Standard Drive Control
Typical settling time after a speed change:
100 ms ... 200 ms
Typical settling
time after after a
sudden load
change: 500 ms
Standard Drive
Control is suita-
ble for the follow-
ing requirements:
– All motor
power ratings
– Ramp-up time 0 → rated speed (depend-
ing on the motor power rating):
1 s (0.1 kW) ... 10 s (18.5 kW)
– Applications with continuous load torque
without sudden load changes
Standard Drive Control is insensitive to inac-
curate motor data settings
550 Hz
Unlike "Dynamic Drive Control," no speed
controller needs to be set
As compared with "configuration for experts":
– Simplified commissioning using prede-
fined motor data
– Reduced number of parameters

Dynamic Drive Control
Typical settling time after a speed change:
•
< 100 ms
Typical settling time
•
after after a sudden
load change: 200ms
Dynamic Drive Con-
•
trol controls and lim-
its the motor torque
Typically achieves a
•
torque accuracy:
± 5 % for 15 % ...
100 % of the rated
speed
We recommend Dynamic Drive Control for the
•
following applications:
– Motor power ratings > 11 kW
– On sudden load changes 10% ... >100% of
the motor rated torque
Dynamic Drive Control is necessary for a ramp-
•
up time 0 → rated speed (depending on the mo-
tor power rating):
< 1 s (0.1 kW) ... < 10 s (18.5 kW).
