问题描述与安全警告
Fanuc R-30i Series Robot Controller 触发了严重的 RAM disk is full 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
Cause: The RAM disk does not have enough available memory to perform the specified command. Note that copying a file to the FROM disk requires that the RAM disk be mounted with enough memory available to temporarily contain the file. Remedy: Delete all unnecessary files and then purge the device. For more information on purging, refer to the PURGE_DEV Built-in in the KAREL Reference Manual. If the device is still full, then back up the files to an off-line device and reformat the device after setting $FILE_MAXSEC to a larger number.
