Figure 8-50
The application class Standard Drive Control reduces the number of characteristics and
setting options:
• A linear and a parabolic characteristic are available.
• Selecting a technological application defines the characteristics.

Requirement
The required
torque is inde‐
pendent of the
speed
The required
torque increa‐
ses with the
speed
306
The closed-loop starting current control optimizes the speed control at low speeds
The converter compensates the voltage drop across the motor stator resistance
Characteristics after selecting Standard Drive Control
Linear and parabolic characteristics
Application exam‐
ples
Conveyor belts,
roller conveyors,
chain conveyors,
eccentric worm
pumps, compres‐
sors, extruders,
centrifuges, agita‐
tors, mixers
Centrifugal
pumps, radial fans,
axial fans
Remark
-
Lower losses in the motor and con‐
verter than for a linear characteris‐
tic.
