Yaskawa inverter disassembly precautions - Solutions - Huaqiang Electronic Network
1. Because the bolt material inside the Yaskawa inverter is soft, if the tool has a large tolerance, it will easily cause damage to the bolt head. It is recommended to equip the maintenance personnel with special tools for import or joint venture brands.
2. Electrolytic capacitors and heat sinks are made of aluminum alloy. Pay attention to the gestures and strength when bolting, so as not to cause bad teeth. If the electrolytic capacitor is bad, it must be tapped again, otherwise the inverter will be damaged again.
3. Since the port machine inverter is mostly on-site maintenance, it is more troublesome to drop the bolt in the inverter or the trench, so the screwdriver head must be magnetic.
4. Since the number of IGBT tubes in G7 inverter is double that of G5 series inverters, the circuit of power part is also more complicated. Therefore, it must be carefully checked according to the circuit diagram during the installation process, and check the U with the multimeter diode file before power-on. Whether the detection values ​​of the V and W three-phase output circuits are consistent.
5. Check whether the number of bolts is the same when disassembling the inverter, which can be used as an auxiliary basis for correct installation.
