Selecting a suitable application class
When selecting an application class, the inverter assigns the appropriate settings to the
motor control.
Motors that can be
operated
Induction motors Induction and synchronous motors
Power Modules that
can be operated
• Pumps, fans, and compressors with flow
characteristic
• Wet or dry blasting technology
• Mills, mixers, kneaders, crushers, agitators
• Horizontal conveyor technology (conveyor
belts, roller conveyors, chain conveyors)
• Basic spindles
• Pumps and compressors with displacement
machines
• Rotary furnaces
• Extruder
• Centrifuge
• Typical correction time after a speed
change: 100 ms … 200 ms
• Typical correc-
tion time after a
load surge:
500 ms
• Standard Drive
Control is suita-
ble for the fol-
lowing require-
ments:
– Motor power
ratings < 45 kW
– Acceleration time 0 → rated speed (de-
pending on the rated motor power):
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 inaccurate motor data settings
• Typical correction time after a speed
change: < 100 ms
• Typical correction
time after a load
surge: 200 ms
• Dynamic Drive
Control controls
and limits the mo-
tor 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 an
acceleration time 0 → rated speed (depend-
ent on the rated motor power):
< 1 s (0.1 kW) … < 10 s (250 kW).
Speed control with lower-level torque control
• Contrary to "Dynamic Drive Control" a
speed controller does not have to be set
• In comparison to "Configuration for experts":
– Simplified commissioning using preas-
signed motor data
– Reduced number of parameters
• Reduced number of parameters when com-
pared to "Configuration for experts"
