Functions
14.10 Closed-loop drive control
Requirement
Standard Drive Control works only with an induction motor.
Description of function
Figure 14-79
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 defines the characteristic:

• Slip compensation is activated.
• Soft starting is not possible.
• Fewer setting options compared to U/f control

Default setting of the U/f control after selecting Standard Drive Control
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
