The driver starts from the start frequency. If the setup frequency is lower than
frequency lower limit during the running process, the driver will keep running
under frequency lower limit until it stops or the setup frequency is higher than
the frequency lower limit.

This function is used to adjust the carrier frequency of the driver. By
adjusting the carrier frequency, the motor noise can be reduced, and the
resonance of the mechanical system can be avoided, so that the leakage
current to the earth and the interference of the driver can be reduced.
When the carrier frequency is low, the output current higher harmonic
component will increase, the motor loss will increase, and the motor
temperature rise will also increase.
When the carrier frequency is high, the motor loss is reduced, and the motor
temperature is decreased, but the driver loss and temperature rise will
increase and so will the interference.
The adjustment of carrier frequency will have influences on the following
performances:
Carrier frequency Low to high
Motor noise high to low
Output current
waveform
poor to good
Motor temperature rise high to low
Driver temperature rise Low to high
Leakage current low to high
