① The closed-loop starting current control optimizes the speed control at low speeds
② The converter compensates the voltage drop across the motor stator resistance
Figure8-50 Characteristics after selecting Standard Drive Control
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 de󹪝nes the characteristics.
