数控机床449报警 449 N AXIS：INV.IPM ALARM
所属分类：新闻中心　发布时间：　点击数：
发那科系统出现，系统是中文的话会显示“449 n轴：INV.IPM报警”；如果系统为英文，则会显示“&449 N AXIS：INV.IPM ALARM”
出现这种故障一般要看对应的N是哪个轴，数控车床一般会是X轴或者Z轴，加工中心则在数控车床的基础上多出了Y轴。所以首先看是哪个轴出现了警报。当然也会出现X、Y、Z轴同时出现449报警的情况。
然后再看449报警的含义，发那科官方给出的解释是：“IPM（智能电源模块）检测到报警”。什么是IPM模块呢？
IPM（Intelligent
Power Module），即智能功率模块（也就是智能电源模块），不仅把功率开关器件和驱动电路集成在一起。而且还内部集成有过电压，过电流和过热等故障检测电路，并可将检测信号送到CPU。它由高速低功耗的管芯和优化的门极驱动电路以及快速保护电路构成。即使发生负载事故或使用不当，也可以保证IPM自身不受损坏。
出现449报警的话，电柜里面驱动器的SVM上也会有对应的数字显示，分别是8、9、A，对应X轴，Y轴和Z轴（也可能是A轴）。
下面给出判断和处理方法:
1.将电机动力线拆下,如果还有报警,则可以肯定是驱动器问题，需要了。
2.如果拆下电机动力线后没有报警,请检查外部动力线相间电阻,以及对地绝缘是否良好。

加工中心故障问题！
请问，我的加工中心经常出现这样的问题，以前偶尔一次现在一天好几次。都是在抬刀的时候出现。 (FANUC Series 21-M机器)
问题出现的时候，我只好完全关机10多分钟，然后再开又没问题了。
414 Servo Alarm : z Axis Detect Err
我有更好的答案
414伺服报警：Z轴检测错误
你检查一下Z轴伺服电机的电源线和编码器 是不是有接触不好的地方，重点是接头的地方，或者编码器线里面有接触不好的地方。
采纳率：48%
电柜里控制Z轴检测的电池没电了，找找电池的位置吧！换一块
你是不是铣叶片啊？？？有用没转台吗？？？是偶发现象的话就只能在报警的时候看看后面驱动器上报警号是多少。并且要监控PLC
制机床电器柜内最大的电磁吸合器的，你看看你电磁吸合器是否确实没有吸合，吸合器线圈是否有电压输入。另外观察一下三轴限位开关是否有被卡死的现象，有些厂家的机床，限位开关的超程开关被压下后只报紧急停止而没有其他报警。
一个电磁阀接触不良了,换一个就好了。用表测一下
