Goodrive300 VFDs provide
the parameter autotuning
function. Correct parameter
autotuning depends on the
correct setting of the name
plate parameters of the motor.
To ensure the control
performance, configure the
standard matched motor for
the VFD. If the power of the
motor configured is greatly
different from that of the
standard matched one, the
control performance of the
VFD degrades significantly.
Note: P02.16 to P02.19 may
be initialized by resetting the
rated power of the motor
(P02.15).

After the motor parameter
autotuning is properly
complete, the values of
P02.20 to P02.22 are updated
automatically. These
parameters are the
benchmark parameters of
high-performance vector
control, directly affecting the
control performance.
When P00.15=1 (rotating
autotuning), the set value of
P02.23 may be automatically
updated by autotuning, In this
case, there is no need to
change the value of P02.23.
When P00.15=2 (static
autotuning), the set value of
P02.23 cannot be updated by
