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 10% for each additional 1kHz carrier frequency.
Setting range: 1.0~15.0 kHz

Motor
parameter
autotuning
0: No operation
1: Rotation autotuning
Comprehensive motor parameter autotune. It is recommended to
use rotation autotuning when high control accuracy is needed.
2: Static autotuning 1
It is suitable in the cases when the motor can not de-couple
from the load.
3: Static autotuning 2
It is suitable in the cases when the motor can not de-couple
form the load. But only for parts of parameters.

AVR function
selection
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. 1 ○
P00.17 Load type
0: Constant Torque Load rated parameters
1: Variable Torque Load rated parameters (fans and
centrifugal water pumps)
CV50 inverters can manage Constant Torque/Variable
Torque loads. With a Variable Torque Load, the same
inverter can manage a one power bigger motor than if it
was a constant torque.
Example : A CV50-150-4F can manage a fan or centrifugal
water pump of 18.5 kW, but a 15 kW crane or conveyor.

Function
restore
parameter
0: No operation
1: Restore the default value
2: Clear fault records
Note:
The function code will restore to 0 after finishing the
operation of the selected function code.
Restoring to the default value will cancel the user
