The speed controller can be tuned for different gains in different speed areas, for slow speed and
above the parameter Field weakening point . Gains for different speed areas are percentages of the
original Speed Controller Gain value.

P2.9.5.5 Speed Controller f0 point ID1300
The speed level in Hz below which the speed controller gain is Speed Controller gain f0 .
P2.9.5.6 Speed Controller f1 point ID1301
The speed level in Hz above which the speed controller gain is Speed Controller P gain .
Gain changes linearly between f0 and f1 points.
P2.9.5.7 Speed Controller gain f0 ID1299
The relative gain of the speed controller as a percentage of the Speed Controller P Gain
when the speed is below the level defined by Speed Controller f0 point .
P2.9.5.8 Speed controller gain in field weakening area ID1298
Relative gain of the speed controller in field weakening area as a percentage of Speed
Controller P Gain values. The set value is reached at two times the Field weakening
point .
