If the Mitsubishi Electric Inverter's regenerative brake duty reaches 85% of the Pr. 70 Special regenerative brake duty setting or higher, set a longer deceleration time and check the settings of Pr.30 Regenerative function selection and Pr. 70 Special regenerative brake duty.
What causes the electronic thermal relay function pre-alarm on Mitsubishi Electric Inverter, and how to resolve it?
If the cumulative value of the electronic thermal O/L relay has reached 85% of the Pr. 9 Electronic thermal O/L relay setting or higher on your Mitsubishi Electric Inverter, reduce the load and frequency of operation. Also, set an appropriate value in Pr. 9 Electronic thermal O/L relay.
What causes output phase loss in Mitsubishi Electric FR-E720-1.5K Inverter?
If the Mitsubishi Electric Inverter detects a loss in one of the three output phases (U, V, W) during operation, ensure the cables are properly wired. If the motor capacity is smaller than the inverter capacity, choose matching inverter and motor capacities.
What to do for write disable error on Mitsubishi Electric FR-E720-1.5K?
If the Mitsubishi Electric Inverter is showing a write disable error, check the setting of Pr. 77 Parameter write selection, the settings of Pr. 31 to Pr. 36 (frequency jump), and the connection of PU and the inverter.
How to unlock password on Mitsubishi Electric FR-E720-1.5K?
If the Mitsubishi Electric Inverter is password locked, enter the password in Pr. 297 Password lock/unlock to unlock the password function before operating.
