Mitsubishi Control Card FR-E5NC Engineer Wang 183-5974-1202

Locate the P and N terminals of the internal DC power supply inside the inverter. Set the multimeter to the resistance X10 range. Connect the red test lead to terminal P, and the black test lead to R, S, and T in sequence. The resistance should be around tens of ohms and basically balanced. Conversely, connect the black test lead to terminal P, and the red test lead to R, S, and T in sequence, and the resistance should be close to infinity. Connect the red test lead to terminal N and repeat the above steps, and you should get the same results. If any of the following situations occur, you can determine that the circuit has an abnormality: A. Unbalanced three-phase resistance, which indicates a rectifier bridge fault. B. The resistance is infinity when the red test lead is connected to terminal P, which confirms a rectifier bridge fault or a starting resistor fault.

Connect the red test lead to terminal P, and the black test lead to U, V, and W in sequence. The resistance should be around tens of ohms, and the resistance of each phase should be basically the same. The reverse resistance should be infinity. Connect the black test lead to terminal N and repeat the above steps, and you should get the same results. Otherwise, it can be confirmed that there is a fault in the inverter module.
