Hello,
In addition to what was told, there is also another topic to take in account during the commissionning. The motor Switching frequency ! this is the frequency of motor signal (not the motor frequency, generally between 0 to 50Hz), this is the switching frequency coming from DC bus and transforming this DC signal to AC PWM signal.
It means a switching from 2kHz or 4kHz up to 16kHz. This switching frequency will generate a noise in motor and this noise will be lower and lower when the frequency increase. The point to take in account is when you increase this setting (SFR) the losses in power module of drive increases, then the drive must be derated.
You get the table of derating inside ATV320 installation manual.
