MVME55006E-0163R变频器的常见故障对于MVME55006E-0163R变频器较常见的故障有驱动厚膜的损坏，此驱动厚膜已不仅仅包含驱动电路了，还包括短路检测，IGBT模块检测，过流检测等，由于良好的保护功能，MVME55006E-0163R的大功率模块很少损坏。在维修中如果碰到驱动厚膜损坏，在没有配件的情况下，我们只能对厚膜进行维修，由于厚膜元器件都焊接于陶瓷片上，散热相当快，特别注意不要因为长时间把烙铁加热于元器件上，而导致器件的损坏。由于受到使用时间的限定，MVME55006E-0163R的散热风扇也会出现故障，常见现象是上电后只听到“嗡嗡”声音，但风扇不转，由于是轴流风扇，风扇线圈和轴承往往都是正常的，检查后发现是偏转电容发生故障了，更换后就恢复了正常。

MVME55006E-0163R变频器的常见故障对于MVME55006E-0163R变频器，应该说性能，质量还是相当可靠，但由于受到周围环境的影响，参数设置的不当，以及不正当的操作，都有可能对变频器造成损坏，当然自然损坏也是每个品牌的变频器不可避免的因素。与以往的ABB变频器不同，MVME55006E-0163R变频器采用了光纤通讯，大大提高了CPU板和I/O板之间的通讯时间，但也有可能引起了“LINK OR HWC”“PPCC LINK”这样的故障出现，这种故障的出现与光纤的损坏不是绝对的。“ PPCC LINK”故障是ACS600变频器较常见的故障，CPU板，I/O板的损坏都有可能导致此故障的出现。开关电源损坏，在MVME55006E-0163R变频器中也会碰到，故障主要出现在开关管上，由于开关管的短路，常常也会导致用于限流的一个功率电阻烧坏。“SHORT CIRCUIT”输出短路故障是我们碰到的最多的一类故障了。

Common faults of MVME55006E-0163R inverter The more common faults of MVME55006E-0163R inverter are the damage of the drive thick film, which not only contains the drive circuit, but also includes the short-circuit detection, IGBT module detection, over-current detection, etc. Due to the good protection function, the high-power MVME55006E-0163R module is seldom damaged. Due to the good protection function, MVME55006E-0163R’s high power modules are rarely damaged. If the driver thick film is damaged during maintenance, we can only repair the thick film without spare parts. Since the thick film components are soldered on the ceramic sheet, the heat dissipation is quite fast, so be especially careful not to damage the device by heating the soldering iron on the components for a long time. Due to the use of time constraints, MVME55006E-0163R cooling fan will also fail, the common phenomenon is that after power on only hear the “buzz” sound, but the fan does not rotate, due to axial fan, fan coils and bearings tend to be normal, after checking the deflector capacitor is found to be faulty, after the replacement of the After replacing the capacitor, it returned to normal.

MVME55006E-0163R inverter common failure For MVME55006E-0163R inverter, it should be said that the performance, quality is still quite reliable, but due to the influence of the surrounding environment, improper parameter settings, as well as improper operation, may cause damage to the frequency converter, of course, the natural damage is the inevitable factors of each brand of inverter. Different from the previous ABB inverter, MVME55006E-0163R inverter adopts fiber optic communication, which greatly improves the communication time between CPU board and I/O board, but it may also cause “LINK OR HWC” “PPCC LINK” faults. “Such a fault appears, the appearance of this fault and the damage to the optical fiber is not absolute. “PPCC LINK” fault is ACS600 inverter more common faults, CPU board, I / O board damage may lead to the emergence of this fault. Switching power supply damage, also encountered in the MVME55006E-0163R inverter, the fault is mainly in the switching tube, due to the short circuit of the switching tube, often also lead to a power resistor used for current limiting burned out. The “SHORT CIRCUIT” output short-circuit fault is the most common type of fault we encountered.
