When Pr.80 Motor capacity "9999," the Pr.80 Motor capacity setting is not changed by IPM parameter initialization. IPM parameter initialization is performed
by setting Pr.998 IPM parameter initialization or the parameter setting mode on the operation panel.
REMARKS
If IPM parameter initialization is performed in rotations per minute (Pr. 998 = "1"), the frequency-related parameters not listed in
the table above and the monitored items are also set and displayed in rotations per minute.
The Pr. 998 setting automatically changes the Pr. 71 setting but does not change Pr. 0 Torque boost and Pr. 12 DC injection brake
operation voltage settings.
