以下是ABB变频器(以ACS800系列为例)常见故障的诊断与处理方法,按故障优先级分类整理,便于快速排查:
一、高频紧急故障(立即停机类)
⚠️ 注意:以上故障需断电复位(控制盘按
RESET
或断电5分钟)。
二、中频功能故障(可尝试复位类)
三、隐性参数故障(无报警但功能异常)
四、硬件级诊断流程
肉眼检查:
变频器风扇是否转动(散热失效易报 OH 过热故障)。
电容是否鼓包(老化导致直流母线电压不稳)。
万用表检测:
输入三相电压:平衡度误差<±5%。
直流母线电压:正常值为输入电压×1.35(如380V输入≈513V)。
输出三相电阻:断开电机,三相阻值偏差<±5%。
示波器抓波(疑难故障):
观察IGBT驱动波形是否正常(缺相或畸变表明驱动板故障)。
五、故障复位与预防措施
强制复位:
参数31.21=3
(允许自动复位3次) → 慎用!仅适用于瞬态干扰。预防性维护:
每年清灰(积尘导致散热不良,过热故障率↑70%)。
每2年更换冷却风扇(参数
38.03
监控风扇寿命)。备份参数:控制盘执行 PARAMETER SAVE(保存至U盘)。
