Description
Defines an added torque value used by the autotune
function.
This value is scaled to motor nominal torque.
Note that the torque used by the autotune function
can also be limited by the torque limits (in parameter
group 30 Limits) and nominal motor torque.
Autotune torque step.
Defines a speed value added to the initial speed for the
autotune routine. The initial speed (speed used when
autotune is activated) plus the value of this parameter
is the calculated maximum speed used by the autotune
routine. The maximum speed can also be limited by the
speed limits (in parameter group
nominal motor speed.
The value is scaled to motor nominal speed.
Note: The motor will exceed the calculated maximum
speed slightly at the end of each acceleration stage.
Autotune speed step.
Determines how many acceleration/deceleration cycles
are performed during the autotune routine. Increasing
the value will improve the accuracy of the autotune
function, and allow the use of smaller torque or speed
step values.
Number of cycles during autotune routine.
Reserved
Selects a source that enables/disables the integral (I)
part of the speed controller.
