Code 206205: <location>Infeed: Voltage dip in at least one line supply phase
Problembeschreibung & Sicherheitswarnung
Die Siemens SINUMERIK 840D CNC hat einen kritischen <location>Infeed: Voltage dip in at least one line supply phase-Alarm ausgelöst. Sofortige Aufmerksamkeit durch einen qualifizierten Bediener oder Wartungstechniker ist erforderlich, um Folgeschäden an der Ausrüstung oder verdorbene Teile während des Fertigungszyklus zu vermeiden. Stellen Sie immer sicher, dass standardmäßige Sicherheits- und LOTO-Verfahren befolgt werden, bevor Sie auf Schaltschränke zugreifen.

Message value: %1 Drive object: A_INF, S_INF Reaction: NONE Acknowledge: NONE Cause: Voltage dip or overvoltage in one or several line supply phases has been detected in operation. The pulses are then inhibited for a time of at leas t 8 ms. The operating signal of the infeed unit in r0863.0 remains and the pulse inhibit due to the phase failure is displayed in r3405.2. Alarm value (r2124, bitwise coded cause of the alarm): Bit 0: Line angle deviation (limit va lue p3463) due to a line supply fault Bit 2: Active current deviation Bit 3: Line frequency deviation (limit values: 115 % * p0284, 85 % * p0285) Bit 4: Line overvoltage (limit value 120 % * p0281 * p0210) Bit 5: Line undervoltage (limit value 20 % * p0210) Bit 7: Peak current fault Bit 8: Smart Mode without VSM (p3400.5 = 0): Line angle deviation Bit 9: Smart Mode: DC link voltage dip Bit 10: Smart Mode: Line currents not symmetrical Remedy: Generally, the following applie s when an alarm message is output: - check the line supply and fuses. - check the line supply quality and system fault level. - check the load. Dependent on the alarm value in r2124, the following applies: Bit 0 = 1: Line fault occurred or poor/incorrect cont roller setting. For poor line quality or frequent line supply changeover operations, when required, limit value p3463 can be increased until the alarm value no longer occurs. Bit 2 = 1: Line fault occurred or poor/incorrect cont roller setting. - check t he controller setting and load. Bit 3 = 1: Line fault occurred. For poor line q uality or frequent line changeover operations, when required, limit values p0284 and p0285 can be incr eased until the alarm value no longer occurs. Bit 4 = 1: Line interrupted or line overvoltage has occurred. Bit 5 = 1: Line interrupted or line undervoltage has occurred. Bit 7 = 1: Peak current trip due to li ne fault or overload. Check the load. Bit 8 = 1: Line fault occurred. Bit 9 = 1: Line undervoltage or overload. Check the load. Bit 10 = 1: Line supply interrupted in at least one line phase. Check the fuses.
