0 Umax delay Delay until the Umax_Threshold parameter kicks in. . The parameter does not kick until this time has elapsed and the limit value has been exceeded. Note: If Une Umax but smaller than Uerd the beginning the search, the regulator will move the coil until reaches Une< Umax_Hysteresis*Umax_Threshold. This limit value may not be exceeded during the search. The search process starts as soon the condition has been met.Page 111 Detailed description REG-DP/ REG-DPA parameters 0 100 10 -2 10 -1 10 0 10 1 Coil position [%] Une in [%] Self-extinguishing current limit detuning Umax-hysteresis Umax-threshold Figure 80: Umax and Umax_Hysteresis 0 Umax_Threshold The regulator allowed perform tuning process long the absolute value the ze- ro sequence voltage Une smaller than the set threshold. A value disables the Umax function. The regula- tor moves the coil until the value has been exceeded. This adjustment takes a hysteresis 25% into account. The function also disabled Umax Uerd.
