问题描述与安全警告
Fanuc R-30i Series Robot Controller 触发了严重的 Cap A over voltage (Cap A volts, Cap B volts) 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 voltage on one of the two input capacitor banks (bank A) has exceeded the high voltage limit. This is normally caused by high input voltage but it could be caused by a faulty switch board, main capacitor, contactor, or V-to-F feedback signal. Remedy: Check the input power (voltage and frequency). Verify the primary reconnect is properly configured for the input voltage.
