*1 Initial value for the FR-F820-02330(55K) or lower and FR-A840-01160(55K) or lower.
*2 Initial value for the FR-F820-03160(75K) or higher and FR-F840-01800(75K) or higher.
*3 When Pr.71 Applied motor = "213, 214, 243, 244, 8093, 8094, 9093, or 9094", the Pr.71 setting is not changed.
*4 When a value other than "9999" is set, the set value is not changed.
*5 110% for SLD rating and 120% for LD rating (Refer to Pr.570 Multiple rating setting on
*6 Use Pr.702 Maximum motor frequency to set the maximum motor frequency or rotations per minute. When Pr.702 ="9999 (initial value)", the
setting of Pr.84 Rated motor frequency is used as the maximum motor frequency or rotations per minute.
*7 The setting value is converted from frequency to rotations per minute. (It differs according to the number of motor poles.)
*8 Refer to page 615
NOTE
• When the motor parameter initialization is performed with the setting in units of rotations per minute (Pr.998 = "12, 14, 8009,
or 9009"), the parameters not listed in the table and the monitor items are also set and displayed in rotations per minute.
