Detailed instruction of parameters
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 reasonal 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 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(autotune totally); It is suitable
in the cases when the motor can not de-couple
form the load. The antotuning for the motor
parameter will impact the control accuracy.
3: Static autotuning 2(autotune part parameters);
when the current motor is motor 1, autotune
P02.06, P02.07, P02.08; and when the current
motor is motor 2, autotune P12.06, P12.07,
P12.08.
