This waiting position can be: 0 Standby position or 0 Tuning point (resonance point including the compensation that was set the last calculation) Default setting: Tuning point A new search process starts if 0 the zero sequence voltage Une leaves the tolerance range or 0 the regulator set perform cyclical control the resonance point. search not start- ed within this time, the message 'Une Umin' triggered. Parameter Message delay (at Umin) The message delay parameter sets the delay for the Umin message.2% Parameter end position (at Umin) In order calculate and estimate the resonance curve, least one measurement point must bigger than the set Umin threshold. This frequently caused the transformer P-coil being temporarily switched off during grid switching.Page 114 Detailed description REG-DP/ REG-DPA parameters We take care it. . the P-coil not reconnected the grid after the switch, there will not be enough zero sequence voltage for the regulation and the regulator will display message. valid estimate cannot made, the P-coil is adjusted waiting position based the parameterization. the zero sequence voltage Une Umin. Default setting: 0. Only then are the measured data accepted for the determination the resonance curve. Default setting: min Figure shows the combination and description the above-mentioned parameters
