F1-02: Motor rated voltage
F1-03: Motor rated current
F1-04: Motor rated frequency
F1-05: Motor rated speed
F1-06: Motor wiring method
F1-07: Motor rated power factor
Based on the rated power of the inverter, match inverter with an applicable Y-series
motor, and the defaults of motor can meet most of needs.
To ensure control performance, the motor and the inverter should match in terms of the
power rating. Usually the power rating of motor is only allowed to be one level lower
than that of the inverter.
After autotuning is over normally, the setting value of F1-08uld match in terms of the
power raved.
When F0-28=1 reset the default, the parameters of F1-00 F1-08uld match in terms

Autotuning Procedure
In parameter setting status, set F0-04=0, and make motor offload.
Set all motor parameters as per the values listed on nameplate correctly:
F1-00: Motor model
F1-01: Motor rated power
F1-02: Motor rated voltage
F1-03: Motor rated current
F1-04: Motor rated frequency
F1-05: Motor rated speed
F1-06: Motor wiring method
F1-07: Motor rated power factor
Set F1-15=1, inverter performs stationary autotuning.
Set F1-15=2, inverter performs rotational autotuning.
It takes about 2 minutes to finish autotuning motor parameters, and the keypad displays
returns the initial power-on status.
Pressing
STOP
RESET
to cancel autotuning in autotuning, and inverter will return parameter
setting status.
If autotuning fails, inverter will trip faults of SrE (Stator Resistance Error) or SIE
(Idling Current Error). Pressing
STOP
RESET
, inverter will return parameter setting status.
Remarks:
The autotuned motor parameters will not vary with motor status. But motor parameters will
vary with temperature changes. If the motor is running with heavy load for a long time and
motor temperature lasts higher for a long time, and in order to obtain a better performance, it
is suggested to autotune motor parameters when motor temperature is high after running with
heaving load. If the motor is running with light load, autotuning shall be conducted when
motor is in cold status.
