(2) Tuning under vector control for PMSM without speed sensor and magnetic pole position sensor
■ Selection of PMSM type and pole position detection method
After identifying the type of the synchronous motor and selecting the magnetic pole position detection mode,
execute tuning based on Figure 4.8-3.
Tuning errors might occur during tuning depending on the type of the synchronous motor and mismatching
of P30 setting. Consult with the motor maker for the type and set the type to P30.
known, execute
tuning as P30=0. In this case, it might be necessary to adjust the starting frequency setting F23 or starting
frequency continuous time F24.
