本系统采用2个CU320,一个CU320带三个1KF7电机(故障号为3003),,另一个CU320带2个1PH7电机(故障号为7841),一天中(8小时)大概出现一次故障报警(报故障时只出现其中一个,不是同时报故障),单出现故障后,复位后故障重复出现,如果断开电源后基本上可以复位故障,请问这个是什么原因,请高手帮忙。
最佳答案
1、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The signal "infeed operation" was withdrawn in operation.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.
2、CU320里没有3003为故障号的故障,报警也没有。只有:A30031、A30032、A30033、F30035、F30036、F30037、A30038、F30039、F30003 这几种故障和报警。你需要重新核实故障号到底为多少。
