frequency to the lowest within the allowable noise, which reduces the controller loss and
radio frequency interference.
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 system has an increase in power loss, temperature rise and interference.
Adjusting the carrier frequency will exert inuences on the aspects listed in the following
table.

Note
On certain environment conditions (the heatsink temperature is too high), the system will reduce
the carrier frequency to provide overheat protection for the controller, preventing the controller
from being damaged due to overheat. If the temperature cannot reduce in this case, the controller
reports the overheat fault.
