Carrier frequency pair impact diagram
The advantage of high carrier frequency: there are more ideal current waveform,
less current harmonics and less motor noise.
The disadvantage of high carrier frequency: switching loss increases, the inverter
temperature increases, the inverter output is affected, the inverter derates under high
carrier frequency; the leakage current of the inverter increases, the electromagnetic
interference on external increases.
The low carrier frequency has contrary the case described above, the too low
carrier frequency will cause the instability of low frequency operation, the torque
reduction even oscillation.
The inverter has been set reasonably before leaving factory. Under normal
circumstances, user does not need change the parameters.
If the frequency that user uses is more than the default carrier frequency, the
derating is required, derating 20%. each increasing of 1K carrier frequency

★
Maximum output frequency is used to set the maximum output frequency of
inverter. User shall note that it is the basis of frequency setting, as well as the basis for
the speed of acceleration and deceleration.

To define the setting mode for upper limit. The upper limit frequency can be set
from either digital setting (F0.10), also from analog input channels, multi-speed setting
or communication settings. When the analog input setting, multi-speed setting or
communication setting is set to upper limit frequency, the analog input setting 100%
corresponds to F0.08 (maximum output frequency) .

☆
Running frequency upper limit is the upper limit of the inverter output frequency.

The value should be less than or equal to the maximum output frequency.

☆
Running frequency lower limit is the lower limit of the inverter output frequency.
When the set frequency is less than the frequency lower limit, the frequency lower
limit will be adopted for running.
Note: maximum output frequency ≥ frequency upper limit ≥ frequency lower
limit.
F0.12 Running direction
selection
0: default ；
1: opposite
2: reverse prohibited
0 ★
0: default After the inverter is powered on, it runs at the actual direction.
1: opposite Used to change the motor rotation, which acts to change the motor
direction of rotation by adjusting any two motor wires.
2: reverse prohibited Used to prohibit reverse running of the inverter for the
specific occasions.
Note: after the parameter is initialized, the motor running direction will be
restored to its original status. When the system debugging is completed, please use
with caution where the change of motor steering is strictly prohibited

AVR function that automatically adjusts the output voltage function. When AVR
function is disabled, the output voltage will vary with the change of the input voltage
(or DC bus voltage) ; when AVR function is enabled, the output voltage will not vary
with the change of the input voltage (or DC bus voltage), the output voltage remains
substantially constant within the range of output capacity.
