Carrier frequency will affect the noise of motor and the EMI of inverter.
If the carrier frequency is increased, it will cause better current wave, less harmonic
current and lower noise of motor.
Notice:
The factory setting is optimal in most cases. Modification of this parameter is
not recommended.
If the carrier frequency exceeds the factory setting, the inverter must be
derated because the higher carrier frequency will cause more switching loss,
higher temperature rise of inverter and stronger electromagnetic interference.
If the carrier frequency is lower than the factory setting, it is possible to cause less output
torque of motor and more harmonic current.

Auto-tuning
0: No action: Forbidding auto-tuning.
1: Rotation auto-tuning:
Do not connect any load to the motor when performing auto-tuning and ensure
the motor is in static status.
Input the nameplate parameters of motor (P2.01~P2.05) correctly before performing
auto-tuning. Otherwise the parameters detected by auto-tuning will be incorrect; it may
influence the performance of inverter.
Set the proper acceleration and deceleration time (P0.08 and P0.09) according to the
motor inertia before performing auto-tuning. Otherwise it may cause over-current and
over-voltage fault during auto-tuning.
The operation process is as follow:
a.
Set P0.12 to be 1 then press the DATA/ENT, LED will display "-TUN-" and flickers.
During "-TUN-" is flickering, press the PRG/ESC to exit auto-tuning.
b.
Press the RUN to start the auto-tuning. LED will display "TUN-0".
c.
After a few seconds the motor will start to run. LED will display "TUN-1" and
"RUN/TUNE" light will flicker.
d.
After a few minutes, LED will display "-END-". That means the auto-tuning is finished
and return to the stop status.
