F0.16 Carrier frequency
It is used to adjust the carrier frequency of the AC drive,
helping to reduce the motor noise, avoid the resonance
of the mechanical system, reduce the leakage current
to ground and reduce interference generated by the AC
drive.
When the carrier frequency is low, the output current
high harmonics increases, the motor power loss
increases and the motor temperature rises also
increases.
When the carrier frequency is high, the motor power
loss reduces, the motor temperature rise decreases,
but the AC drive has an increase in power loss and
temperature rise, generates more interference.
Adjusting carrier frequency will cause the following
inuences.
Carrier frequency Low............High
Motor noise Large............Small
Output current

Bad............Good
