For the ACS300 inverter, the common fault is the damage of the switching power supply. The switching power supply of the ACS300 inverter uses a waveform generator integrated block called LT1244, which is similar to the UC3844 function. Due to the sudden change of the working voltage and the damage of the load carried by the switching power supply, this integrated block is often damaged. Due to the long years of use, the Electrolytic capacitor has reached its service life, The capacitor used for filtering has become the direct cause of damage to the switching power supply. ACS300 uses Mitsubishi’s IPM module, which has a relatively low probability of failure. The module is damaged and can only be replaced, but before replacement, it is necessary to ensure that the drive circuit is completely normal.
2、 Common faults of ACS500 frequency converter
A common fault for ACS500 frequency converters is damage to the driving thick film, which not only includes the driving circuit, but also includes short circuit detection, IGBT module detection, overcurrent detection, etc. Due to its good protection function, the high-power module of ACS500 is rarely damaged. If there is damage to the thick film of the drive during maintenance, without accessories, we can only repair the thick film. As the thick film components are welded to ceramic chips, heat dissipation is quite fast. Special attention should be paid not to damage the components by heating the soldering iron on them for a long time. Due to the limitation of service time, the Computer fan of the ACS500 will also fail. The common phenomenon is that after power on, only the “buzz” sound is heard, but the fan does not rotate. Because it is an axial fan, the fan coil and bearing are usually normal. After inspection, it is found that the deflection capacitor has failed, and after replacement, it returns to normal.
