代码 206200: <location>Infeed: Failure of one or several line phases

Message value: Drive object: A_INF, S_INF Reaction: OFF2 (OFF1) Acknowledge: IMMEDIATELY (POWER ON) Cause: Failure overvoltage in one or several line supply phases. The fault can be output in two operating states: 1. During the power-on phase of the infeed unit. The measured line supply angle deviates from the regul ar characteristic for a 3-phase system - the PLL cannot be synchronized. The fault occurs immediately after power-up if, wh en operating with a VSM, the phase assignment L1, L2, L3 at the VSM differs from t he phase assignment at the power unit. 2. While the infeed is operational. After a voltage dip has been detected or an overvolt age (note A06205) in one or several line phases a fault occurred within 100 ms (also refer to other relevant messages). Generally, before fault message F06200 is output, Alarm A06205 occurs at leas t once, whose warning value can provide information regarding the cause of the line supply fault. Probable causes of the fault: - voltage dip on the line side or phase failure or overvoltage lasting longer than 10 ms. - overload condition on the load side with peak current. - commutating reactor missing. Remedy: - check the line supply and fuses. - check the connection and size (rating) of the line commutating reactor. - check and correct the phase assignment at the VSM (X521 or X522) and at the power unit. - check the load. - if failed in operation, carefully note the prev ious alarm messages A 6205 with alarm values.
