• 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 influences on the aspects listed in the following
table.
Table 7-1 Influences of carrier frequency adjustment
Carrier frequency Low High
Motor noise Large Small
Output current waveform Bad Good
Motor temperature rise High Low
Controller temperature rise Low High
Leakage current Small Large
External radiation interference Small Large
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.

It is used to set the encoder type matching the motor.
When F1-25 is set to 1 (Synchronous motor), set this parameter correctly before auto-
tuning; otherwise, the motor cannot run properly.
When F1-25 is set to 0 (Asynchronous motor), this parameter is automatically changed to 2.
You need not modify it manually.
