to oscillation.
The carrier frequency of VFD is set properly by
default, and it should not be changed 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: 1.0–15.0kHz
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.
4: Dynamic autotuning 2 (only valid to
asynchronous motors)
5: Static autotuning 2 on certain parameters (only
valid to asynchronous motors)
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.
