What to do if the control panel display is not operating on Mitsubishi Inverter?
If the control panel display of your Mitsubishi Inverter is not operating, begin by ensuring that the control panel is securely connected. Then, check for any short circuits across the PC-SD terminals. Finally, verify that the wiring and installation are correct.
Why parameter write cannot be performed on Mitsubishi Inverter?
If you cannot perform parameter writes on your Mitsubishi Inverter, check Pr. 77, 'parameter write inhibit selection'. Make sure that the inverter is not currently in operation. Ensure that you pressed the SET (WRITE) key. Verify that you are not attempting to set a parameter outside of its allowed range or attempting to set the operation mode.
