0: Auto-tuning disabled (use of internal parameters).
1: Application of individual settings of f203 (after execution: 0).
2: Auto-tuning enabled (after execution: 0).
When auto-tuning, set the following parameters at least, as specified on the nameplate
of the motor: f101~f104.
Set f100 to 2 before the start of operation. Tuning is performed at the start of the motor
then.
Check to be sure that the setting of the parameter f101 and that of the parameter f102
agree with the base frequency (rated rotational speed) and base frequency voltage
(rated voltage) of the motor to be operated, respectively. If not, set the parameters
correctly.
When using the inverter to control the operation of a motor smaller in capacity by one
grade or more, be sure to set the motor rated current setting parameter (f103) properly.
Vector control may not operate properly if the motor capacity differs from the applicable
rated capacity of the inverter by more than two grades.
If current wave forms oscillate during operation, increase the speed control stability
factor (f208). This is effective in suppressing oscillation.
Precautions on auto-tuning:
