Note 1)
Set a value more than 2kHz at

Sensorless vector performance will be reduced when using a motor less than

half of the rated capacity of the VFD.
Multiple motors cannot be driven by sensorless vector control.

Note 2) To operate the motor over rated frequency, consult the motor manufacturer about
the maximum allowable rotation speed.
CT (Heavy Duty) load: - 10 ~ 50℃
VT (Normal Duty) load: - 10~ 40℃
(It is recommended that you use less than 80% load when you use VT load at 50℃.
And if ambient temperature is above 40℃, Carrier frequency should be lower than
default value.)
