7.8.9 Configuration 510 – Field-Oriented Control of Synchronous
Machine, Speed Controlled
An extension module EM-RES for evaluation of resolver signals is required for operation
of a synchronous machine (control method 5xx).
An extension module EM-ABS for signal evaluation is required for operation with
absolute encoders (Hiperface, EnDat2.1, SSI).
For connection of the resolver or absolute encoder, also refer to operating instructions
of extension module.
Configuration 510 contains the functions for speed-controlled, 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 necessary resolver feedback results in a precise speed
and torque performance.
