10.5.5 Asynchronous motors in control mode CFC
Either standard asynchronous motors (e.g. DRN.. motors) or asynchronous servomo-
tors (e.g. DRL.. motors) can be used in control mode CFC. SEW‑EURODRIVE recom-
mends using asynchronous servomotors to achieve optimum benefit from the advant-
ages of the control mode CFC.
Standard asynchronous motors in control mode CFC
In comparison to control mode VFC
using CFC. The full motor magnetization is maintained in each operating state, so that
the highest requirements for dynamics 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 operating mode VFC
are thus lower.
