1. If the problem code E.OC1 is displayed on the screen of the Mitsubishi inverter, it means that the overcurrent may speed up the operation when the inverter is accelerating. We need to check whether the output of the inverter is short-circuited and whether the main power supply is operating normally;
2. If the problem code E.OC2 is displayed on the screen of the Mitsubishi inverter, then there may be a situation where the overcurrent is broken at the time of acceleration, and we need to check whether the output of the inverter has a short circuit;
3. If the problem code E.OC3 is displayed on the screen of the Mitsubishi inverter, it means that the overcurrent is broken during the deceleration, and we also need to check whether the output is short-circuited and whether the braking action is generated too early;
4. If the problem code E.OV1 is displayed on the screen of the Mitsubishi inverter, then the overvoltage has an open circuit at the time of acceleration, and we need to see if the speed of the overvoltage is too slow.
5. If the problem code E.OV2 is displayed on the screen of the Mitsubishi inverter, then the overvoltage has caused a broken circuit at a fixed speed, and we need to check whether the load of the inverter has changed rapidly.
6. If the problem code E.OV3 is displayed on the screen of the Mitsubishi inverter, then it means that the overvoltage is open when decelerating or aborting, and we need to check whether the inverter is operating in a state of rapid deceleration;
7. If the problem code E.THM is displayed on the screen of the Mitsubishi inverter, then we need to check whether the inverter is operating in an overload state;
8. If the problem code E.THT is displayed on the screen of the Mitsubishi inverter, the inverter prompts us to check whether the inverter is operating in an overloaded state;
9. If the problem code E.IPF appears on the screen of the Mitsubishi inverter, then it means that the inverter has a power outage maintenance situation, and we need to investigate why there will be an instantaneous power outage;
10. If the problem code E.UVF is displayed on the screen of the Mitsubishi inverter, then it means that the inverter has undervoltage maintenance, and we need to check whether there is a short circuit between P and P1.

Power factors affecting Mitsubishi inverters
The speed regulation of Mitsubishi inverter power regulator is adopted, one is to regulate the speed according to the requirements, and the other is to save energy. It is based on the following elements:
1) The frequency conversion speed regulation system has low loss and high operating power.
2) The motor is always kept running at a low slip rate, which reduces the rotor loss.
