代码 75608: [Channel %1: ] RESU: NC memory limit reached, RAM type %2
问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 [Channel %1: ] RESU: NC memory limit reached, RAM type %2 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
Definitions: A memory limit was reached on writing to file cc_res u.mpf. The possible area for return traveling is shortened. RAM type = 1: File cc_resu.mpf is created in the buffer memory (SRAM). The buffer memory is therefore full. If the buffer memory is used and if alar m 75608 with RAM type 1 is output, system alarm 6500 will be output simultaneously. RAM type = 2: The memory limit was reached on creating file cc_resu.mpf in the dynamic memory (DRAM part program memory). Reaction: Alarm display. Remedy: RAM type = 1: Increase size of buffer memory ($MN_MM_USER_MEM_BUFFERED) or the available space in the buffer memory, e.g. by unloading unused parts programs. Alternatively the ring buffer can be decreased via MD $MC_RESU_RING_BUFFER_SIZE. Program Continuation: Clear alarm with the Delete key or NC START.
