Supported
function
Electronic motor stator shorting, overexcitation fast
deceleration, master‑slave control, maximum torque
per ampere (MTPA) control, inertia auto‑tuning,
acceleration feedforward, droop control, free
programming and self‑adaption of speed loop
parameters, overvoltage suppression, voltage dip
suppression, automatic voltage adjustment (AVR
generator bus voltage control), 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.)
