successful. Use P.295 to set the password. Enter the initial password into P.294 to decrypt the
parameter password and to modify or to set up various parameters.
• P.295 is the parameter for setting up the password. The password has to be greater than 1. Once the
password setup is completed, P.295 will display 1. After deleting the password, P.295 will display 0.
Once the password is set, no parameter can be modified, except P.294. P.998 and power shutdown
have no effect on the password. The parameters can be revised only after the decryption.
Note: Bring the inverter to the factory for decryption if the password is forgotten.

<Setting>
• When P.300=0, no motor parameter auto-tuning function is required for normal V/F curve
operation.
• For general magnetic vector control, please set P.300 to 2. The frequency will be altered due to
elevated voltage and increased compensatory motor load.
• For executing the motor parameter auto-tuning function, set P.301 to 1 or 2 and press the forward
rotation or the reverse rotation key. During the measuring process, the operation panel will flicker
and display “TUN”. If the measurement is success, the operation panel will display “TEND” and
flicker. If the measurement fails, the operation panel will flicker “FAL”. Press down
