<Setting>
• P.294 is the parameter that provides the decrypt function. P.294 will be zero if the
decryption is 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
