代码 P10-10212: I2 IGBT OvrTemp
问题描述与安全警告
Allen-Bradley PowerFlex 750 Drive 触发了严重的 I2 IGBT OvrTemp 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
Type: Resettable Fault Coast Y Y An IGBT over temperature has been detected. This power layer interface board calculated this value based on the NTC temperature plus a rise based on recent currents through the inverter. • Check the NTC temperature that is displayed in [In Heatsink Temp] (port 10) and verify that it is not near the limit. If this value is near the limit, check for cooling problems caused by a blocked or slow heatsink fan. • Check the output phase current displayed in [In U Phase Curr], [In V Phase Curr], and [In W Phase Curr] (port 10) for an imbalance. • Check for high-current operation at low speeds, since nearly all current goes through one IGBT in this case. • Replace the power layer interface board.
