high carrier frequency, the VFD needs to be derated
for use, meanwhile, the leakage current will
increase, which increases electromagnetic
interference to the surroundings.
While low carrier frequency is the contrary. Low
carrier frequency will cause unstable operation at
low frequency, decrease the torque, or even lead to
oscillation.
The carrier frequency of VFD is set properly by
default, and it should not be changed by users at
will.
If the default carrier frequency is exceeded during
use, derating is required, derate by 10% for every
additional 1k carrier frequency.
Setting range: 1.2–15.0kHz

Motor parameter
autotuning
0: No operation
1: Rotary autotuning; carry out comprehensive
motor parameter autotuning; rotary autotuning is
used in cases where high control precision is
required;
2: Static autotuning 1 (comprehensive autotuning);
static autotuning 1 is used in cases where the motor
cannot be disconnected from load;
3: Static autotuning 2 (partial autotuning) ; when
current motor is motor 1, only P02.06, P02.07 and
P02.08 will be autotuned; when current motor is
motor 2, only P12.06, P12.07 and P12.08 will be
autotuned.

AVR function
0: Invalid
1: Valid during the whole process
Automatic voltage regulation function is used to
eliminate the impact on the output voltage of VFD
when bus voltage fluctuates.
