5.11.13 Offline auto tuning for a frequency search
During V/F control, the accuracy of the "frequency search", which is used to detect the motor speed for the automatic restart
after instantaneous power failure and flying start, can be improved.
*1 For the FR-F860-00680 or lower.
*2 For the FR-F860-01080 or higher.
*3 The same operation is performed for the both settings.
