问题描述与安全警告
Fanuc R-30i Series Robot Controller 触发了严重的 SS/SE timing invalid 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: This error is caused by timing problems with Sealing commands (SS or SE). Timing problems could occur if the robot does not have enough time to plan for a sealing instruction before the robot passes that point in the path. For example: If the user is using a sealing schedule with a gunon delay of 1000ms and a gunoff delay of -1000ms and the robot executes the seam in 1500ms, the Dispense tool will detect the logic problem and post this fault. A path which has many sealing instructions very close to each other (closer than 30mm at 500mm/sec) is likely to have this problem. Remedy: Make sure there is adequate time for each SS and SE to execute. You may do this by making sure you have only the minimum number of points in your path that you require. Dispense tool works best with as few points as possible. Also, make sure none of your schedules have gunon, gunoff, or equipment delays beyond that which is needed (usually between -100ms and +100ms is adequate). NOTE: Whenever a SEAL-131 occurs, the robot MUST be cold started to recover.
