Standard asynchronous motors in CFC control mode

In comparison to the VFC^PLUS control mode, higher dynamic properties can be achieved using CFC. The full motor magnetization is maintained in each operating state, so that the highest dynamic requirements are met. Due to the voltage reserves required for this, standard asynchronous motors are operated with a lower base speed in this operating mode than in the VFC^PLUS operating mode. Power yield and energy efficiency are consequently lower.
