Rockwell Automation Liqui-Flo DBT Reach Drive - Manual (Page 138)

3-112 DBT Reach Drive User Manual
Sets the speed loop bandwidth and determines the dynamic behavior of the speed
loop. As bandwidth increases, the speed loop becomes more responsive and can
track a faster changing speed reference.
Adjusting this parameter will cause the drive to calculate and change Ki Speed Loop
(445) and Kp Speed Loop (447) gains.
Represents the time in seconds for a motor coupled to a load to accelerate from zero
to base speed at rated motor torque. The drive calculates Total Inertia during the
autotune inertia procedure.
Adjusting this parameter will cause the drive to calculate and change Ki Speed Loop
(445) and Kp Speed Loop (447) gains.
Value of the speed regulator output.
Sets a limit on speed in the negative direction, when in FVC Vector mode. Used in
bipolar mode only. A value of zero disables this parameter and uses Maximum Speed
for reverse speed limit.
