Configuration 410 - Sensorless Field-Oriented Control - BONFIGLIOLI ACTIVE Cube ACU 201-01 Operating Instructions Manual

6.7.3 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 a high drive dynamics at a high load moment.
