The parameter does not kick until this time has elapsed and the limit value has been exceeded. . 0 Umax delay Delay until the Umax_Threshold parameter kicks in.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. The search process starts as soon the condition has been met. This limit value may not be exceeded during the search. this threshold value exceeded during the search, the P-coil will immediately retracted order leave the Une Umax zone. A value disables the Umax function. The regula- tor moves the coil until the value has been exceeded. The function also disabled Umax Uerd. 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 adjustment takes a hysteresis 25% into account. Default setting: 30% 0 Umax_Hysteresis A normal search performed when Une<Umax Hysteresis Umax_Threshold
