F07841 ——“整流单元撤消运行信号”故障。
故障原因：
The signal "infeed operation" was withdrawn in operation.
- interconnection of the binector input for the signal "infeed operation" is either incorrect or missing (p0864).
- the enable signals of the infeed were disabled.
- due to a fault, the infeed withdraws the signal "infeed operation".
解决办法：
- check the interconnection of the binector input for the signal "infeed operation" (p0864).
- check the enable signals of the infeed and if required, enable.
- remove and acknowledge an infeed fault.
       建议你核查一下参数p0864的值是否设置正确。很多时候，F07841故障都是由于p0864的值漏设而引起的。
