Analog Input Fault
Mitsubishi · D700 Inverter
What does E.AIE mean?
This fault appears when there is a mismatch between the type of signal (voltage or current) being input to terminal 4 and the inverter's configuration settings. Specifically, it occurs if voltage (current) is applied while Pr. 267 (Terminal 4 input selection) and the physical voltage/current input switch are set differently. This can lead to incorrect speed commands or erratic operation.
Additional Steps
Steps 1–2 are listed in Priority Fix.
- 3
Ensure consistency: either provide a frequency command by current input OR set Pr. 267 and the voltage/current input switch to voltage input, depending on the intended control scheme.
- 4
Check the wiring to terminal 4 for proper connection, shielding, and signal integrity, ensuring no external interference.
