Programming Parameters
7-57
Parameter 699 – Auto Tune Speed [Auto Tune Speed]
Internal units : 4096 = 1000H = 1 pu = Base motor speed
Programming Terminal units: RPM
Minimum Value: – Base Speed
Maximum Value: +Base Speed
Default Value: +Base Speed
Description: This parameter is the top speed of the motor during an
auto tune velocity motor test, velocity system test, and field flux tune.
For a field flux tune, the motor must be at the auto tune speed before
performing the field flux tune.
Parameter 700 – Velocity Desired Bandwidth [Vel Desired BW]
Internal units : RAD x 10
Programming Terminal units: RAD/Sec
Minimum Value: 0.1
Maximum Value: 150
Default Value: 5
Description: This parameter specifies the velocity loop bandwidth
requested by the user and determines (along with Parameter 702) the
dynamic behavior of the velocity loop. The desired bandwidth is
limited to the maximum achievable bandwidth which is calculated by
the velocity processor (VP) during auto tune system test. The
velocity loop becomes more responsive and reproduces the velocity
reference more accurately as the bandwidth is increased. However,
the velocity may exhibit more oscillation and overshoot as it is
increased.
Parameter 701 – Velocity Maximum Bandwidth [Vel Max BW]
Internal units : RAD x 10
Programming Terminal units: RAD/Sec
Minimum Value: 0.1
Maximum Value: 150
Default Value: 50
Description: This parameter specifies the maximum achievable
velocity loop bandwidth as calculated by the VP. The maximum
bandwidth is a function of the velocity loop damping factor
(Parameter 702) and the system inertia. The VP updates the
parameter during auto tuning and whenever the user reads this
parameter. The maximum velocity loop bandwidth is not changeable
by the user.
