Characteristics after selecting the application class Standard Drive Control
Selecting application class Standard Drive Control reduces the number of characteristics and
the setting options:
● A linear and a parabolic characteristic are available.
● Selecting a technological application defines the characteristic.
● The following cannot be set - ECO mode, FCC, the programmable characteristic and a
specific voltage setpoint.

Requirement Application examples
The required Conveyor belts, roller
torque is inde- conveyors, chain con-
pendent of the veyors, eccentric worm
speed pumps, compressors,
extruders, centrifuges,
agitators, mixers
The required Centrifugal pumps,
torque increases radial fans, axial fans
with the speed

The closed-loop starting current control optimizes the speed control at low speeds
The inverter compensates the voltage drop across the motor stator resistance
Characteristics after selecting Standard Drive Control
Remark
-
Lower losses in the motor and inverter
than for a linear characteristic.
