•
The carrier frequency will affect the running noise of the motor. The higher the carrier frequency, the
lower the noise made by the motor. So properly set the carrier frequency.
•
When the value > the factory setting, HD31 should be derated by 5% when per 1kHz is increased
compared to the factory setting.
