28.12 PI ADAPT MAX SPD
Maximum 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
coefficients at certain speeds. The coefficients are defined individually for both gain and integration
time.
When the actual speed is below or equal to
28.03 INTEGRATION TIME
COEF respectively.
When the actual speed is equal to or exceeds
