Description
Speed controller settings.

Displays the speed controller output that is
transferred to the torque controller. See the control
chain diagram on page
This parameter is read-only.
Limited speed controller output torque.
Defines the proportional gain (K
controller. Too 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
