代码 P10-10129: I1 DC Bus Imbal
问题描述与安全警告
Allen-Bradley PowerFlex 750 Drive 触发了严重的 I1 DC Bus Imbal 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 Either the lower or upper leg of the capacitor bank is getting too much voltage (based on the bus voltage, measured voltage across the lower leg, and a calculation to find the voltage across the upper leg) or the voltage sensing components are damaged. • Check the value of the bus bleeder resistor and bus balancing resistor and replace as necessary. • Inspect the capacitor bank for leakage or damage and replace as necessary. Replacing the capacitor bank assembly also replaces the bus balancing resistor. • Measure the voltage on each half of the bus to confirm the calculations. If the bus measurements aren’t correct, replace the power interface board and/or inverter power supply board.
