Functions
* These parameters are measured automatically when offline auto-tuning is performed. They can also be
changed to desired value manually after tuning.
 If H002/H202 remains 00 after the completion of auto-tuning, the motor parameters obtained by
auto-tuning are not reflected in the operation data.
 If the auto-tuning result indicates that the tuning was aborted, perform auto-tuning again.
 If a trip occurs during auto-tuning, the auto-tuning processing is forced to stop.
(No abort message appears. Trip display is given higher priority.)
After removing the cause of the trip, set H001 to 01 and then perform the auto-tuning again.
 If the offline auto-tuning is performed with "free V/f setting" selected as the control method, the
Inverter displays the abort message and stops processing.
 During auto-tuning, the deceleration stop tends to slow under certain conditions such as when the
incoming voltage is high. In this case, press the STOP key and adjust the parameters so that the
value of Over voltage Suppression Integral Time Setting (b134) will decrease and the value of
Overvoltage Suppression Level During Deceleration (b131) will increase.
 If an overcurrent trip occurs during acceleration while auto-tuning is in progress, adjust the
Parameter
No.
