* 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.
....Specifications differ according to the date assembled.
Refer to page 346

REMARKS

When initialization of the IPM driving parameters is performed using rotations per minute ( Pr. 998 = "1 or 12"),
increments of the other parameters, which are not listed in the above table, also change to rotations per minute. In
addition, the increments of monitor displays change from frequency to rotations per minute for all monitored items.
 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. ( Refer to page 123 )

Acceleration time in low-speed
range Acceleration time in the low-speed range ("rated motor frequency/10" or
lower) is set.

Deceleration time in low-speed
range Deceleration time in the low-speed range ("rated motor frequency/10" or
lower) is set.

Control method selection IPM motor test operation is selected. 88
820
Speed control P gain 1
The proportional gain during speed control is set. (Setting this parameter
higher improves the trackability for speed command changes. It also reduces
the speed fluctuation due to a load fluctuation.)
90
821
Speed control integral time 1
The integral time during speed control is set. (Setting this parameter
shortens the return time to the original speed when the speed fluctuates due
to a load fluctuation. )
