Auto-tuning
Soft Sound
The VAT2000 is performed with an Auto-tuning function which simplifies the adjustment of critical control parameters. The Automatic
tuning can be performed in four mode of operation, V/f Constant
Torque, V/f Variable Torque, Vector Sensorless, Full Vector with
sensor.
VAT2000 Soft Sound technology reduces the characteristic whine
from inverter-driven motors and eliminates the side-effects of conventional noise reduction methods, specifically that of raising the
carrier frequency.
Soft Sound varies the carrier frequency in one of two fixed patterns,
from a user-selected base frequency (between 2.1kHz and 5kHz). By
keeping the carrier frequency range low, torque performance is
notably better tha a high-frequency carrier.
The high frequency induced problems of hot running, degrading of
winding insularion, arcing across motor bearings, high leakage
currents, interference,.... These are decreased by using Soft Sound
carrier frequency.
