)0-15 Carrier frequency 0.5–16.0 kHz Model dependent
It is used to adjust the carrier frequency of the AC drive, helping to reduce the motor noise,
avoiding the resonance of the mechanical system, and reducing the leakage current to the
earth and interference generated by the AC drive.
If the carrier frequency is low, output current has high harmonics, and the power loss and
temperature rise of the motor increase.
If the carrier frequency is high, power loss and temperature rise of the motor declines.
However, the AC drive has an increase in power loss, temperature rise and interference.
