See the control chain diagram on page 492.
Displays the ramped and corrected speed reference (before
speed error calculation). See the control chain diagram on
page 492.
This parameter is read-only.
Speed reference used for speed error calculation.
Displays the speed feedback used for speed error calculation.

Speed feedback used for speed error calculation.
Displays the filtered speed error. See the control chain
diagram on page 492.

Displays the speed controller output that is transferred to the
torque controller. See the control chain diagram on page 493.
This parameter is read-only.
Limited speed controller output torque.
Defines the proportional gain (K
high a gain may cause speed oscillation. The figure below
shows the speed controller output after an error step when
the error remains constant.

If gain is set to 1, a 10% change in error value (reference -
actual value) causes the speed controller output to change by
10%, ie. the output value is input × gain.
