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).

44.10 TiEMF (i-part EMF controller)
Integral time of the EMF controller. TiEMF (44.10) 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 EMF with KpEMF (44.09) = 3, if the EMF error is 5% of

(15 % from proportional part and 15 % from integral part).
Setting TiEMF (44.10) to 0 ms disables the integral part of the EMF controller and resets its integrator.
