Auto-tuning(1)
Function description
The auto-tuning procedure automatically sets the motor parameter related to sensorless vector control.
Since sensorless vector control needs motor parameter, the standard motor parameters have been set
at the factory.
Therefore, when an inverter exclusive-use motor is used or when a motor of any other manufacture is
drive, the motor parameter is detected by auto-tuning because the parameters are not matched.
Function setting
Follow the steps below to auto-tune the inverter, finally set the parameter H01.
F02, F03 setting : Set the time the range that over-current or over-voltage trip event not occurs.
Set the same as setting F02.
H03 setting : Set the motor rating.

H04 setting : set the motor poles
A01 setting : set the frequency command source to 0 (potentiometer)
A03 setting : set the base frequency(example 60Hz)
F01 setting : set the operation frequency except 0hz (by the potentiometer)
A53 setting : select output voltage for motor.
A33 setting : set DC injection braking setting to 0(disable).
H01 setting : select the auto-tuning mode (2).
After setting above parameters, press the RUN key on the standard operator.
Note 1. When B26 is set to 1, this motor series is displayed.
