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 from 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

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.

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 password, use this function with caution.

Start mode
0: Start-up directly:start from the starting
frequency P01.01
1: Start-up after DC braking: start the motor
from the starting frequency after DC braking
(set the parameter P01.03 and P01.04). It is
suitable in the cases where reverse rotation
may occur to the low inertia load during
starting.
2: Reserved.
Note: It is recommended to start the
synchronous motor directly.
