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.
200 r/min when Pr. 788 "Low speed range torque characteristic selection" = "0".
13.33 Hz when Pr. 788 "Low speed range torque characteristic selection" = "0".
110% for SLD, 120% for LD, 150% for ND, and 200% for HD
(Refer to Pr. 570 "Multiple rating setting" page 5-201.)
The Pr. 702 "Maximum motor frequency" is used as the maximum motor frequency. When Pr. 702 =
"9999 (initial value)", the Pr. 84 "Rated motor frequency" is used as the maximum motor frequency.
NOTE If IPM parameter initialization is performed in rotations per minute (Pr. 998 = "3003, 8009, or
9009"), the parameters not listed in the table and the monitored items are also set and displayed
in rotations per minute.
