官方故障排除步驟
Message value: %1 Drive object: All objects Reaction: OFF1 (OFF2) Acknowledge: IMMEDIATELY (POWER ON) SINAMICS-Alarms Cause: The input current of the Terminal Module analog input has exceeded the threshold value parameterized in p4061[x]. This fault can only occur if p4056[x] = 3 (4... 20 mA with monitoring) is set. Index x = 0: Analog input 0 (X522.1 to.3) Index x = 1: Analog input 1 (X522.4 to.5) Fault value (r0949, interpret decimal): The component number (p0151) of the module involved is specified at the units, tens and hundreds digit. The thousands digit specifies the analog input involved: 0: Analog input 0 (AI 0), 1: Analog input 1 (AI 1) Remedy: Check the connection to the signal source for interruptions. Check the magnitude of the injected current - it is possible that the infed signal is too low. Please note that the input has a load resistance of 250 Ohm. The input current measured by the Termi nal Module can be read out from r4052[x].
