7.8.12 Configuration 610 – Sensorless Field-Oriented Control of
Synchronous Machine, Speed Controlled
Configuration 610 contains the functions for sensorless field-oriented control of a synchronous
machine with resolver feedback. The separate control of torque and flux-forming current enables high
drive dynamism with a high load moment. The missing resolver feedback results in slightly lower
dynamism and speed quality compared to Configuration 510.

7.8.13 Configuration 611 – Sensorless Field-Oriented Control of
Synchronous Machine with Technology Controller
Configuration 611 extends the functionality of the sensorless field-oriented control of a synchronous
machine of Configuration 610 by a Technology Controller. The Technology Controller enables a control
based on parameters such as flow rate, pressure, filling level or speed.
