Base Motor Speed
This parameter is the speed of the motor
during an auto tune velocity motor test,
system test, and system ID measure.
4096 is base speed

Enums:
This parameter specifies the velocity loop
bandwidth requested by the User and
determines the dynamic behavior of the
velocity loop. The maximum value for this
parameter is changed by the drive when a
request is made to update the the velocity
loop gains. The vel loop becomes more
responsive and is able to track a faster
changing vel ref as bandwidth is increased.
System and noise limitations will establish
a practical upper limit however.
This parameter indicates the status of
certain conditions related to the autotune
function. This is a bit–coded parameter
that is not changeable by the user.

This parameter determines the dynamic
behavior of the velocity loop. The damping
factor influences the amount of overshoot
the velocity loop will exhibit during a tran-
sient.
This parameter represents the time, in se-
conds, for a motor coupled to a load to ac-
celerate from zero to base speed, at rated
motor torque. This parameter is calculated
by the Autotune System Inverter Test.
