官方故障排除步骤
Message value: Drive object: A_INF, B_INF, S_INF Reaction: NONE Acknowledge: NONE SINAMICS-Alarms Diagnostics Manual (DAsl), 03/2009 Cause: After an OFF1 = 1 no valid current offset measurem ent was able to be made within the monitoring time (p3491) before closing the line contactor. The current offset is set to 0. See also: p3491 (Infeed I-offset measurement monitoring time) Remedy: - check the DC link for a ground fault. A ground fault can destroy parts and components! - Check the monitoring time setting and if required increase (p3491). At least 100 ms is required for a valid measurement (p3491 > 100 ms). Notice: If there is no valid measurement, then under certain circumstances the quality of the DC link control will be reduced. See also: p3491 (Infeed I-offset measurement monitoring time)
