西门子，施耐德和松下伺服驱动器维修常见问题及解决方法

一、西门子直流伺服驱动系统故障维修10例

例1．进线快速熔断器熔断的故障维修 故障现象：一台配套SIEMENS 8MC的卧式加工中心，在电网突然断电后开机，系统无法起动。

分析与处理过程：经检查，该机床X轴伺服驱动器的进线快速熔断器已经熔断。该机床的进给系统采用的是SIEMENS 6RA系列直流伺服驱动，对照驱动器检查伺服电动机和驱动装置，未发现任何元器件损坏和短路现象。

检查机床机械部分工作亦正常，直接更换熔断器后，起动机床，恢复正常工作。分析原因是由于电网突然断电引起的偶发性故障。

例2．SIEMENS 8MC测量系统故障的维修 故障现象：一台配套SIEMENS 8MC的卧式加工中心，当X轴运动到某一位置时，液压电动机自动断开，且出现报警提示：Y轴测量系统故障。断电再通电，机床可以恢复正常工作，但X轴运动到某一位置附近，均可能出现同一故障。

分析与处理过程：该机床为进口卧式加工中心，配套SIEMENS 8MC数控系统，SIEMENS 6RA系列直流伺服驱动。由于X轴移动时出现Y轴报警，为了验证系统的正确性，拨下了X轴测量反馈电缆试验，系统出现X轴测量系统故障报警，因此，可以排除系统误报警的原因。

检查X轴在出现报警的位置及附近，发现它对Y轴测量系统(光栅)并无干涉与影响，且仅移动Y轴亦无报 警，Y轴工作正常。再检查Y轴电动机电缆插头、光栅读数头和光栅尺状况，均未发现异常现象。

考虑到该设备属大型加工中心，电缆较多，电柜与机床之间的电缆长度较长，且所有电缆均固定在电缆架上，随机床来回移动。根据上述分析，初步判断由于电缆的弯曲，导致局部断线的可能性较大。

维修时有意将X轴运动到出现故障点位置，人为移动电缆线，仔细测量Y轴上每一根反馈信号线的连接情况，*终发现其中一根信号线在电缆不断移动的过程中，偶尔出现开路现象；利用电缆内的备用线替代断线后，机床恢复正常。
