Parameters 177
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
Reserved.

Selects a source that enables/disables the integral (I) part of
the speed controller.
