Due to the long duration of the New Year's holiday, some companies have a New Year's holiday for more than two weeks, and the equipment may lose power. After the power is off, the temperature of the inverter/servo drive decreases, and the dust attached to the inverter/servo drive is easy to get wet, resulting in the reduction of insulation of other equipment such as the inverter/servo drive, and even a short circuit, which will cause damage to the inverter/servo equipment. In order to avoid this, we would like to draw your attention to the following:
1. Enterprises with power conditions during the New Year holiday can keep the equipment uninterrupted.
2. Before resuming work, check whether the power cable, control cable, and other cables are damaged, and whether the protective sleeve and insulation layer of the wire are complete.
3. Before resuming work, check whether the inverter is damp, condensation and water droplets. If so, please dry it first (choose ventilation and heating methods).
4. Before resuming work, check whether there is significant damage to the mechanical part of the load at the back end of the inverter/servo drive (not smooth, stuck, etc.).
5. When resuming work, please power on in an orderly manner, close the main switch first, then close other opening switches, and finally close all kinds of equipment in order to power on.
6. After checking the above matters, please do not run immediately after the inverter/servo drive is energized, and first power on for 20 minutes in order to facilitate the boring inverter/servo drive components, and then run after the investigation has no problems.
7. After the investigation is no problem, first low-speed test operation for a period of time, do a good job of pre-inspection before normal operation, and then operate normally after there is no abnormality.
