238 Parameters
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 is multiplied by
and the integration time divided by
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.
