Energy saving control, inertia auto‑tuning, acceleration
feedforward, droop control, master‑slave control, free
programming and self‑adaption of speed loop
parameters, load observer, overvoltage suppression,
voltage dip suppression, overexcitation fast
deceleration, automatic voltage adjustment (AVR
generator bus voltage control), flying start, DC braking,
continuous operation after smooth switchover to SVC
upon encoder abnormality, and FVC‑to‑SVC switchover
at designated frequency (This can avoid abnormal
operation caused by high‑speed jitter of the encoder.)
