*2 120% for LD rating and 150% for ND rating (Refer to Pr.570 Multiple rating setting on
*3 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).
*4 The setting value is converted from frequency to rotations per minute. (It differs according to the number of motor poles.)
NOTE
• When the motor parameter initialization is performed with the setting in units of rotations per minute (Pr.998 = "8009 or 9009"),
the parameters not listed in the table and the monitor items are also set and displayed in rotations per minute.
