P02.15–P02.19 correctly
according to the information
on the nameplate of the
synchronous motor.
The K120 series VFD
provides the parameter
autotuning function.
Whether parameter
autotuning can be performed
properly depends on the
settings of the motor
nameplate parameters.
In addition, you need to
configure a motor based on
the standard motor
configuration of the VFD. If
the power of the motor is
greatly different from that of
the standard motor
configuration, the control
performance of the VFD
degrades significantly.
Note: Resetting the rated
power of the motor (P02.15)
can initialize the parameters
of P02.16 to P02.19.

After motor parameter
autotuning is properly
performed, the values of
P02.20 to P02.22 are
automatically updated.
These parameters are the
reference parameters for
high-performance vector
control, directly affecting the
control performance.
When P00.15=1 (rotary
autotuning), the set value of
P02.23 may be automatically
updated by autotuning, In
this case, there is no need to
