Dependency:

In case of sensorless vector control, integrator freezing must be selected (Bit 1 "Integral freeze (SLVC)" of
P1400 has to be set) to save the integrator output.

Note:

-

If the setting command is not connected (P1477=0), a pending value is read in after pulse enable at the
end of the excitation time (P0346) and the integral component of the speed controller is set once.

-

If the P1482 (integral component of speed controller) is connected upon pulse enable, the integral
component of the controller is set to the last value prior the pulse inhibit.

-

Neither function works after flying start.
