If regenerative energy causes the inverter's internal main circuit DC voltage to reach or exceed the specified value, the protective circuit is activated to stop the inverter output. Ensure that you keep load stable.
How to reset Mitsubishi Electric FR-D720-2.2K Inverter?
Turn OFF the reset command.
What to do if Mitsubishi Electric FR-D720-2.2K Inverter shows heatsink overheat?
If the heatsink overheats, the temperature sensor is actuated and the inverter output is shut off. Set the surrounding air temperature to within the specified limits.
What causes write disable error on Mitsubishi Electric FR-D720-2.2K Inverter?
A write disable error can occur if you attempt to make parameter settings when Pr. 77 Parameter write selection has been set to disable parameter write, if the frequency jump setting range overlapped, or if the PU and inverter cannot make normal communication. Check the setting of Pr. 77 Parameter write selection, the settings of Pr. 31 to Pr. 36 (frequency jump), and the connection of the PU and inverter.
What does mode designation error mean on Mitsubishi Electric FR-D720-2.2K?
A mode designation error appears if a parameter setting is attempted in the External or NET operation mode with Pr. 77 not set to "2", or if a parameter setting is attempted when the command source is not at the operation panel. Set the operation mode to the "PU operation mode" or disconnect the parameter unit (FR-PU04/FR-PU07) to make parameter settings.
How to fix write error during operation on Mitsubishi Electric Inverter?
A write error during operation can occur when parameter write was performed during operation with a value other than "2" set in Pr. 77 and the STF (STR) is ON, or if the inverter is operating. Set "2" in Pr. 77 or stop the inverter before making parameter settings.
What causes stall prevention stop on Mitsubishi Electric Inverter?
If the output frequency has fallen to 1Hz by stall prevention operation and remains for 3s, a fault appears and the inverter output is shut off. Reduce the load weight to prevent this.
What to do when Mitsubishi Electric FR-D720-2.2K shows input phase loss?
If function valid setting (=1) is selected in Pr. 872 Input phase loss protection selection and one phase of the three phase power input is lost, the inverter output is shut off. Ensure that the cables are wired properly.
How to resolve analog input fault on Mitsubishi Electric FR-D720-2.2K Inverter?
An analog input fault appears if voltage(current) is input to terminal 4 when the setting in Pr.267 Terminal 4 input selection and the setting of voltage/current input switch are different. Give a frequency command by current input or set Pr. 267 Terminal 4 input selection, and voltage/current input switch to voltage input.
What happens when Mitsubishi Electric FR-D720-2.2K has output phase loss?
If one of the three phases (U, V, W) on the inverter's output side (load side) is lost during inverter operation, the inverter stops the output. Ensure that the cables are wired properly.
