This function can meet the needs of some special loads, for example, when the frequency
outputs 300Hz and corresponding voltage outputs 200V (supposed voltage of inverter power
supply is 400V), turnover frequency F118 should be set to 300Hz and F152 is set to
（
200÷400
）
×100=50. And F152 should be equal to 50.
Please pay attention to nameplate parameters of motor. If the working voltage is higher than
rated voltage or the frequency is higher than rated frequency, motor would be damaged.
Carrier-wave frequency of inverter is adjusted by setting this code function. Adjusting
carrier-wave may reduce motor noise, avoid point of resonance of mechanical system,
decrease leakage current of wire to earth and the interference of inverter.
When carrier-wave frequency is low, although carrier-wave noise from motor will increase, the
current leaked to the earth will decrease. The wastage of motor and the temperature of motor
will increase, but the temperature of inverter will decrease.
When carrier-wave frequency is high, the situations are opposite, and the interference will raise.
When output frequency of inverter is adjusted to high frequency, the setting value of
carrier-wave should be increased. Performance is influenced by adjusting carrier-wave
frequency as below table:
Carrier-wave frequency
Low → High
Motor noise
Loud → Low
Waveform of output current Bad → Good
Motor temperature
High → Low
Inverter temperature
Low → High
Leakage current
Low → High
Interference
Low → High
