-
Speed controller
autotune mode
Defines a control preset for the speed controller autotune
function. The setting affects the way the torque reference
will respond to a speed reference step.
Smooth
Slow but robust response.
0
Normal
Medium setting.
1
Tight
Fast response. May produce too high a gain value for
some applications.
2
Mechanical time constant of the drive and the machinery
as determined by the speed controller autotune function.
The value can be adjusted manually.
-
0.00 … 1000.00 s
Mechanical time constant.
10 = 1 s
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
) and nominal motor torque.
10.00%
0.00 … 100.00%
Autotune torque step.
100 = 1%
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
) and 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.
10.00%
0.00 … 100.00%
Autotune speed step.
100 = 1%
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.
10
1…10
Number of cycles during autotune routine.
1 = 1
Displays the output of the proportional (P) part of the
speed controller. See the control chain diagram on
page
This parameter is read-only.
-
-30000.0…30000.0% P-part output of speed controller.
See par.
46.03
Displays the output of the integral (I) part of the speed
controller. See the control chain diagram on page
This parameter is read-only.
-
-30000.0…30000.0% I-part output of speed controller.
See par.
46.03
No.
