The Mitsubishi inverter can be reset using several methods. It's important to note that when the inverter is reset, internal calculated values and the retry count for the electronic overcurrent protection are cleared. The reset process typically takes about 1 second after the reset command is released. There are three main ways to reset the inverter: 1. **Using the Operation Panel**: Press the STOP/RESET button on the operation panel. This method is only available when the inverter’s protection function (heavy fault) is active. For more details on heavy faults, refer to page 228 of the manual. 2. **Power Cycle**: Turn off the power supply to the inverter and then turn it back on. This is a straightforward method that often resolves minor errors or malfunctions. 3. **Reset Signal (RES)**: Apply a 0.1-second or longer signal to the RES input. When the RES signal is activated, the display will show "Err" (flashing), indicating that the inverter is in the reset state. These methods provide flexibility depending on the situation and access to control interfaces. Always ensure that the system is properly configured and safe before performing any reset operations.
