When checking the dust accumulation inside Yaskawa inverter, you can follow the following steps:
1. Power off and prepare
Cut off the power: First of all, ensure that Yaskawa inverter has been completely powered off, and the surface of the LCD and LED screen are all extinguished for at least 5 minutes to prevent the risk of electric shock.
Tools: Prepare tools suitable for cleaning, such as a vacuum cleaner, soft cloth, and brush. Avoid using tools such as pressure fans that may produce a lot of dust.
2. Open the shell
Remove the enclosure: Carefully remove the enclosure of the frequency converter, in accordance with safe operating procedures, so that the internal components can be reached.
Protection: During the disassembly process, pay attention to protect the surrounding components and lines to avoid damage.
3. Check and clean
Check the heat sink: The heat sink is one of the main parts of the dust accumulation inside the inverter. Use a vacuum cleaner or a soft cloth to gently remove dust from the heat sink. If the dust is too much or difficult to remove, you can use dry air with appropriate pressure to purge.
Check the cooling fan: The cooling fan is also prone to dust accumulation. Check the fan blades for dust accumulation in and around them and clean them with a vacuum cleaner or a soft cloth. At the same time, check the running status of the fan for abnormal sound or vibration.
Check the power component: Dust may also be attached to the surface of the power component. Gently wipe with a soft cloth or brush to ensure that the surface of the component is clean and dust-free.
Check other parts: In addition to the above key parts, you should also check other parts inside the inverter, such as capacitors, resistors, etc., to ensure that there is no dust accumulation on their surface.
4. Precautions
Avoid damaging parts: During the cleaning process, avoid using sharp tools or excessive force to avoid damaging the parts inside the inverter.
Pay attention to dust: During the disassembly and cleaning process, pay attention to prevent dust from entering other parts of the inverter.
Record and inspection: After each cleaning, the cleaning date and cleaning situation should be recorded for reference in the next cleaning. At the same time, regular comprehensive inspection of the inverter to ensure that the equipment is in good condition.
5. Reinstall and test
Reinstall the enclosure: After cleaning is complete, reinstall the enclosure of the inverter in the reverse order as it was removed.
Power-on test: Ensure that all components are properly installed and connected before powering back on. Then, the inverter is powered on to test to ensure that the equipment can operate normally.
