Initial value for the FR-F820-02330(55K) or lower and FR-F840-01160(55K) or lower.
Initial value for the FR-F820-03160(75K) or higher and FR-F840-01800(75K) and higher.
Setting Pr. 71 "Applied motor" = "213, 214, 243, 244, 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.
110% for SLD, 120% for LD (refer to Pr. 570 "Multiple rating setting" page 5-68).
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.)
NOTE If PM parameter initialization is performed in rotations per minute (Pr. 998 = "12, 14, 8009, or
9009"), the parameters not listed in the table and the monitored items are also set and displayed
in rotations per minute.
