Description
Activates the flux adaption enable function.
Flux adaption disabled.
Flux adaption enabled.
Activates (or selects a source that activates) the
speed controller auto tune function. See section
Speed controller autotune
The autotune will automatically set parameters
25.02 Speed proportional gain
integration time 25.37 Mechanical time constant
and
Not activated.
Activated.
Terms and abbreviations
Source selection (see
Defines a control preset for the speed controller auto
tune function. The setting affects the way the torque
reference will respond to a speed reference step.
Slow yet robust response.
Normal response.
Fast response which can produce high gain value.
Mechanical time constant of the drive and the
machinery as determined by the speed controller
autotune function. The value can be adjusted
manually.
Mechanical time constant.
Defines an added torque value used by the auto tune
function. This value is scaled to the motor nominal
torque.
Note: The torque used by the auto tune function can
also be limited by the torque limits (in parameter
30 Limits
group ) and the nominal motor torque.
Defines a speed value added to the initial speed for
the auto tune function. The initial speed (speed used
when auto tune is activated) plus the value of this
parameter is the calculated maximum speed used by
the auto tune routine. The maximum speed can also
be limited by the speed limits (in parameter group 30
Limits) and nominal motor speed. The value is scaled
to the motor nominal speed.
Note: The motor will exceed the calculated maximum
speed slightly at the end of each acceleration stage.
Determines how many acceleration/deceleration
cycles are performed during the auto tune routine.
Increasing the value will improve the accuracy of the
auto tune function, and allow the use of smaller
torque or speed step values.
