Factory Default

0.85 x Base Motor Speed

Minimum Value

0.3 x Base Motor Speed

Maximum Value

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.

Bit 8 – 11 = Not Used
Bit 12 = Timeout
Bit 13 = No Trq Lim

Bit 0 = Executing
Bit 1 = Complete
Bit 2 = Fail
Bit 3 = Abort
Bit 4 = Flux Active
Bit 5 = Not Ready
Bit 6 = Not Zero Spd
Bit 7 = Running

Maximum Value

1111 1111 1111 1111

This parameter indicates the value of the
internal location selected by the Autotune
TP Sel parameter, 48.
