6.5 Motor control
Default setting after selecting the application class Standard Drive Control
Selecting application class Standard Drive Control adapts the structure and the setting
options of the U/f control as follows:
● Starting current closed-loop control: At low speeds, a controlled motor current reduces
the tendency of the motor to oscillate.
● With increasing speed, transition from closed-loop starting current control into U/f control
with voltage boost depending on the load.
● Soft starting is not possible.
● Fewer parameters
