505 [Kd Ln Ls Bus Reg]
Line Loss Bus Reg Kd is a derivative gain,
which is applied to the sensed bus voltage to
anticipate dynamic changes and minimize
them. A larger value reduces overshoot of the
bus voltage relative to the inertia-ride through
bus voltage reference.

506 [Angl Stblty Gain]
Angle Stability Gain adjusts the electrical
angle to maintain stable motor operation. An
increase in the value increases the angle
adjustment.

507 [Volt Stblty Gain]
Adjusts the output voltage to maintain stable
motor operation. An increase in the value
increases the output voltage adjustment.

508 [Stability Filter]
The Stability Filter coefficient is used to
adjust the bandwidth of a low pass filter. The
smaller the value of this coefficient, the lower
the bandwidth of the filter.

509 [Lo Freq Reg KpId]
This proportional gain adjusts the output
voltage at very low frequency in response to
the reactive, or d-axis, motor current. A larger
value increases the output voltage change.

510 [Lo Freq Reg KpIq]
The proportional gain adjusts the output
voltage at very low frequency in response to
the active, or q-axis, motor current. A larger
value increases the output voltage change.
Default:

511 [Ki Cur Reg]
This integral gain adjusts the output voltage
in response to the q and d axis motor
currents. A larger value increases the output
voltage change.

512 [Kp Cur Reg]
This proportional gain adjusts the output
voltage in response to the q and d axis motor
currents. A larger value increases the output
voltage change.

523 [Bus Utilization]
This value sets the drive output voltage limit
as a percentage of the fundamental output
voltage when operating in 6 step mode.
Values above 95% increase harmonic
content and jeopardize control stability. This
output voltage limit is strictly a function of
input line and resulting bus voltage.

0.1%
524 [PWM Type Sel]
Allows selection of the active PWM type. A
value of 0 is default, and results in a change
of PWM method at approximately 2/3 of rated
motor frequency. If this is unacceptable for
harmonic or audible reasons, a value of 1
disables the change.
