[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.

[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.

[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.

[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.

[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.

[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.
