*1 When a value other than "9999" is set, the set value is not changed.
*2 The rated motor rotations per minute (frequency), maximum motor rotations per minute (frequency), number of motor poles, and rated
motor current are as follows.
Rated motor rotations per
minute (frequency)
Maximum motor rotations per
minute (frequency)
Number of motor poles
Rated motor current
NOTE
• When the motor parameter initialization is performed with the setting in units of rotations per minute (Pr.998 =
"3044"), the parameters not listed in the table and the monitor items are also set and displayed in rotations per
minute.

(other than EM-A)
• The settings in Pr.10, Pr.422, and Pr.665 are changed to the settings shown in the following table by selecting
a motor other than EM-A with the IPM initialization on the operation panel or with Pr.998 PM parameter
initialization. For other parameters whose settings are to be changed, refer to the Instruction Manual (Detailed).
