Diag-Motor Cntl
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.

1
✔✔
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.
Default:
Min/Max:
Units:
64
0/32767
1
✔✔
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:
Min/Max:
Units:
64
0/32767
1
✔✔
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.
Default:
Min/Max:
Units:
44
0/32767
1
✔✔
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.

Diag-DACs
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.
Default:
Min/Max:
Units:
95.0%
85.0/100.0%
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.
Default:
Min/Max:
Units:
0

Diag-Vector Cntl
525 [Torq Adapt Speed]
Selects the operating frequency/speed at which the
adaptive torque control regulators become active as
a percent of motor nameplate frequency.
Default:
Min/Max:
Units:
10.0%
0.0/100.0%

✔✔
526 [Torq Reg Enable]
Enables or disables the torque regulator.

✔✔
529 [Torq Reg Trim]
Torque Regulator trim gain. A larger value increases
the developed torque. Typically used to compensate
for losses between developed and shaft torque.
Default:
Min/Max:
Units:
