• To operate the inverter with the auto-tuned data after normal completion of auto-tuning, be
sure to change the 1st Motor Parameter selection (H002) setting to 01.
• Adjust the DC Injection Braking Selection (A051) and Output Voltage Gain (A045) values
according to the user environment.

Operations in case of error
If auto-tuning is aborted by an error, review the preset parameters and check the rated motor
torque ratio of the inverter to that of the motor. If the load is too heavy, disconnect the load and
retry auto-tuning.
If the error persists or auto-tuning is still aborted, enter the motor parameter values directly.
For details, refer to 6-2-4 Motor Parameter Settings on page 6-11.
