HV580L Series Frequency Inverter

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.
Adjusting the carrier frequency will exert influences on the aspects listed in the following table:
Carrier frequency
Low
→ High
Motor noise
Large
→ Small
Output current waveform
Bad
→ Good
Motor temperature rise
High
→ Low
AC drive temperature rise
Low
→ High
Leakage current
Small
→ Large
External radiation interference
Small
→ Large
The factory setting of carrier frequency varies with the AC drive power. If you need to modify the carrier
frequency, note that if the set carrier frequency is higher than factory setting, it will lead to an increase in
temperature rise of the AC drive's heatsink. In this case, you need to de-rate the AC drive. Otherwise, the AC
drive may overheat and alarm.

It is used to set whether the carrier frequency is adjusted based on the temperature. The AC drive
automatically reduces the carrier frequency when detecting that the heatsink temperature is high. The AC
drive resumes the carrier frequency to the set value when the heatsink temperature becomes normal. This
function reduces the overheat alarms.
