44.03 M1TiFex (i-part field current controller)
Integral time of the field current controller
. M1TiFex (44.03) defines the time within the integral part of the
controller achieves the same value as the proportional part.
Example:
The controller generates 15 % of motor nominal field current [
M1NomFldCur (99.11)] with M1KpFex (44.02) =
3, if the field current error is 5 % of
M1NomFldCur (99.11). On that condition and with M1TiFex (44.03) = 200
ms follows:
−
the controller generates 30 % of motor nominal field current, if the current error is constant, after 200 ms
are elapsed (15 % from proportional part and 15 % from integral part).
Setting
M1TiFex (44.03) to 0 ms disables the integral part of the field current controller and resets its
integrator.

M1NomVolt (99.02)
