The advantage of high carrier frequency: ideal
current waveform, little current harmonic wave
and motor noise.
The disadvantage of high carrier frequency:
increasing the switch loss, increasing inverter
temperature and the impact to the output
capacity. The inverter needs to derate on high
carrier frequency. At the same time, the leakage
and electrical magnetic interference will increase.
Applying low carrier frequency is contrary to the
above, too low carrier frequency will cause
unstable running, torque decreasing and surge.
The manufacturer has set a reasonable carrier
frequency when the inverter is in factory. In
general, users do not need to change the
parameter.
When the frequency used exceeds the default
carrier frequency, the inverter needs to derate
20% for each additional 1k carrier frequency.
Setting range:1.0~15.0kHz
0: No action
1: Rotation autotuning
2: Static autotuning1（overall autotuning）
3: Static autotuning1（part autotuning）
0:Invalid
1:Valid during the whole procedure
The auto-adjusting function of the inverter can
cancel the impact on the output voltage of the
inverter because of the bus voltage fluctuation.
0:G type, for the constant torque load of rated
parameters
1:P type; for the variable torque load of rated
parameters (fans and water pumps)
GD200L series inverters can use G/P type, the
available motor power of G type is small one
