5.6.2.2 Configuration 410 –
Sensorless Field-Oriented Control
Configuration 410 contains the functions for sensorless, field-oriented control of a 3-
phase machine. The current motor speed is determined from the present currents
and voltages in combination with the machine parameters. Separate control of torque
and flux-forming current enables high drive dynamism at a high load moment.
