代码 SRVO-040: Mastered at mark pos(G:%d)
问题描述与安全警告
Fanuc R-30i Series Robot Controller 触发了严重的 Mastered at mark pos(G:%d) 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: Zero position master is done with mark position (not with zero position). Remedy: This message is only for S-420iR. S-420iR has the mark at non-zero position for J2 and J3. So Zero position master is not done with zero pos for S-420iS. Confirm the position of each axis to be at mark position. If the robot is not S-420iR, $scr_grp.$robot_model may be wrong. Set correct $scr_grp.$robot_model.
