Figure14-79 Default setting of the U/f control after selecting Standard Drive Control
The Standard Drive Control mode has the following properties:
• At low speeds, a controlled motor current reduces the tendency of the motor to oscillate.
• With increasing speed, the converter changes from controlled motor current to U/f control
with load-dependent voltage boost.
• Selecting a technological application de󹪝nes the characteristic:

① A voltage boost optimizes open-loop speed control at low speeds
② The converter compensates the voltage drop across the stator resistance of the motor
Figure14-80 Characteristics after selecting Standard Drive Control
• Slip compensation is activated.
• Soft starting is not possible.
• Fewer setting options compared to U/f control
