代码 P10-10204: I2 Overcurr UPos
问题描述与安全警告
Allen-Bradley PowerFlex 750 Drive 触发了严重的 I2 Overcurr UPos 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 instantaneous overcurrent (IOC) has occurred in the U, V, or W phase, positive or negative leg. • Reduce the mechanical load. • Check the motor and connections. • With motor disconnected, run the drive in open loop, in V/Hz mode and check for sufficient output phase-to-phase voltages. If an IOC occurs immediately after restarting the drive, check the appropriate current sensor. • Check the power and signal connections to the gate driver board for the phase that is identified, or replace it. The IGBT could also have failed open (and the opposite leg is receiving excess current).
