PARAMETERS
5.14.15
Offline auto tuning for a frequency search

For the FR-A860-01080 or lower.

For the FR-A860-01440 or higher.
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.
