问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 <location>Topology: Too many components on one line 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 or connection number: %1, fault cause: %2 Drive object: All objects Reaction: NONE Acknowledge: IMMEDIATELY Cause: For the selected communications clock cycle, t oo many DRIVE-CLiQ components are connected to one line of the Control Unit. Fault value (r0949, interpret hexadecimal): xyy hex: x = fault cause, yy = com ponent number or connection number. 1yy: The communications clock cycle of the DRIVE-CLiQ connection on the CU is not sufficient for all read transfers. 2yy: The communications clock c ycle of the DRIVE-CLiQ connection on th e CU is not sufficient for all write transfers. 3yy: Cyclic communication is fully utilized. 4yy: The DRIVE-CLiQ cycle starts bef ore the earliest end of the applicat ion. An additional dead time must be added to the control. Sign-of-life errors can be expected. 5yy: Internal buffer overflow for net data of a DRIVE-CLiQ connection. 6yy: Internal buffer overflow for rece ive data of a DRIVE-CLiQ connection. 7yy: Internal buffer overflow for s end data of a DRIVE-CLiQ connection. Remedy: Check the DRIVE-CLiQ connection: Reduce the number of components on the DRIVE-CLiQ line involved and distribute these to other DRIVE-CLiQ connections of the Control Unit. This means that communication is uniformly distributed over several communication lines. Re fault value = 1yy - 4yy in addition: - increase the sampling times (p0112, p0115).
