Application exam‐
ples
● 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

● Standard Drive Control is suitable for the
following requirements:
– All motor power ratings
– 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
● 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
– 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).
