Applies a gain to the V/f pattern during
deceleration (L3-04=4). Returns to normal
values after ramp to stop or at re-acceleration.
To improve the braking power of
overexcitation, increase the gain by 1.25 to
1.30.
If overcurrent or overload occur during
high-slip deceleration, reduce the high-slip
suppression current level. Set as a percentage
of the drive rated current.
0: Disabled
1: Enabled only when rotating forward
2: Enabled only when in reverse

n6: Tuning of Resistance between Motor Lines

Use n6 parameters to adjust the motor line-to-line resistance.
Tunes the line-to-line motor resistance
continuously during operation.
0: Disabled
1: Enabled

n8: Permanent Magnet (PM) Motor Control

Use n8 parameters to control the PM motor control.
Sets the gain for internal speed feedback
detection control. This parameter does not
typically require adjustment.
Increase this setting if hunting occurs.
Decrease to lower the response.
Sets the time constant to make the pull-in
current and actual current value agree.
Decrease the value if the motor begins to
oscillate.
Increase the value if it takes too long for the
current reference to equal the output current.
Defines the amount of current provided to the
motor during no load operation at a constant
speed.
Set as a percentage of the motor rated current.
Increase this setting when hunting occurs while
running at a constant speed.
Sets the amount of d-axis current when using
Energy Saving control.
