7.13 Adapng the speed controller gain
If the motor and the reel is considered a single system with a rigid mass, the gain of the speed
c
ontroller will be directly proporonal to the moment of inera. During the winding process,
the moment of inera changes. The gain adjustment is required in order to adjust the gain of
the speed controller to the moment of inera.
In correspondence with the selected method, an adjustment factor is calculated based on
either the current diameter or the moment of inera. The adjustment factor is used to per-
form a mulplicave evaluaon of the gain factor for the speed controller. The congured
gain only has an eect at maximum diameter or maximum moment of inera. The gain in the
motor control is evaluated in the parameter Speed controller sengs: Gain. It is only when
the factor is 100 [%] that the value from the parameter Speed controller sengs: Gain is
eecve. 40x2900:001
