If the Mitsubishi Electric Inverter experiences a PU stop, turn the start signal off and release.
What to do if Mitsubishi Electric Inverter trips due to overcurrent during acceleration?
Here are some possible solutions: 1. Increase the acceleration time. 2. If "E.OC1" is continuously lit at startup, disconnect the motor and then start the inverter. 3. Inspect the wiring to ensure there is no output short circuit or ground fault. 4. Enable stall prevention operation. 5. Set the base voltage (rated voltage of the motor) in Pr. 19 Base frequency voltage.
How to fix write disable error on Mitsubishi Electric FR-E740-060 Inverter?
A write disable error on your Mitsubishi Electric Inverter may occur due to several reasons: * If Pr. 77 Parameter write selection is set to disable parameter write, check this setting. * If the frequency jump setting range is overlapping, review the settings of Pr. 31 to Pr. 36 (frequency jump). * If the PU and inverter are not communicating correctly, verify the connection between the PU and the inverter.
What to do if Mitsubishi Electric FR-E740-060 Inverter shows regenerative brake prealarm?
If you're seeing a regenerative brake prealarm on your Mitsubishi Electric Inverter: 1. Try increasing the deceleration time. 2. Make sure that the Pr. 30 Regenerative function selection and Pr. 70 Special regenerative brake duty settings are configured correctly.
Why is Mitsubishi Electric FR-E740-060 showing electronic thermal relay function prealarm?
