代码 201420: <location>Topology: Comparison a component is different
问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 <location>Topology: Comparison a component is different 警报。需要由合格的操作员或维修技师立即处理,以防止在制造周期中对设备造成二次损坏或导致零件报废。在接触电气控制箱之前,请务必确保遵循标准安全和停机挂牌 (LOTO) 程序。
官方故障排除步骤
Message value: Component number: %1, component class target: %2, component class actual: %3, fault cause: %4 Drive object: All objects Reaction: NONE Acknowledge: NONE Cause: The topology comparison has detected differences in the actual and target topologies in relation to one component. There are differences in the electronic rating plate. Alarm value (r2124, interpret hexadecimal): ddccbbaa hex: aa = component number of the component, bb = component class of the target tolopology, cc = component class of the actual topology, dd = fault cause dd = 01 hex = 1 dec: Different component type. dd = 02 hex = 2 dec: Different Order No. dd = 03 hex = 3 dec: Different manufacturer. dd = 04 hex = 4 dec: Connection changed over for a multi-component slav e (e.g. Double Motor Module) or defective EEPROM data in the electronic rating plate. dd = 05 hex = 5 dec: A CX32 was replaced by an NX10 or NX15. dd = 06 hex = 6 dec: An NX10 or NX15 was replaced by a CX32. Note: Component class and component type are described in F01375. The drive system is no longer booted. In this stat e, the drive control (closed-loop) cannot be enabled. SINAMICS-Alarms Remedy: Adapting the topologies: - check the component soft-wired connections against t he hardware configuration of the drive unit in the commissioning software and correct differences. - parameterize the topology comparison of all components (p9906). - parameterize the topology comparison of one components (p9907, p9908). Note: Under "Topology --> Topology view" the commissi oning software offers improved diagnostics capability (e.g. setpoint/actual value comparison).
