Parameters Control method
FR-A800 5 - 79
Initial value for the FR-A820-03160(55K) or lower and FR-A840-01800(55K) or lower.
Initial value for the FR-A820-03800(75K) or higher and FR-A840-02160(75K) and higher.
Setting Pr. 71 "Applied motor" = "333, 334, 8093, 8094, 9093, or 9094" does not change the Pr. 71
setting.
When a value other than "9999" is set, the set value is not changed.

The Pr. 702 "Maximum motor frequency" is used as the maximum motor frequency (rotations per
minute). When Pr. 702 = "9999 (initial value)", the Pr. 84 "Rated motor frequency" is used as the
maximum motor frequency (rotations per minute).
*
The setting value is converted from frequency to rotations per minute. (The value after the conversion
differs according to the number of motor poles.)
