Parameters 275
Minimum actual speed for speed controller adaptation.
Speed controller gain and integration time can be adapted
according to actual speed (
).
This is done by multiplying the gain (
) and integration time (
) by coefficients at certain speeds. The
coefficients are defined individually for both gain and
integration time.
When actual speed is below or equal to
, the gain and integration time are multiplied by
respectively.
When actual speed is equal to or above
, no adaptation takes place (the coefficient is 1).
When actual speed is between
, the coefficients for the gain
and integration time are calculated linearly on the basis of the
breakpoints.
