If the Mitsubishi Electric Inverter shuts down due to a power failure lasting longer than 15ms, the instantaneous power failure protection activates. To resolve this, address the cause of the power failure, install a backup power supply, or configure the automatic restart function (Pr. 57).
How to fix Mitsubishi Electric FR-F700 Inverter overcurrent shut-off during acceleration?
If the Mitsubishi Electric Inverter's output current exceeds approximately 170% of the rated current during acceleration, the protective circuit will activate and stop the inverter. You can increase the acceleration time, disconnect and restart the motor, or ensure the downward acceleration time is not too long in vertical lift applications.
What to do for regenerative brake prealarm on Mitsubishi Electric FR-F700 Inverter?
If the regenerative brake duty reaches or exceeds 85% of the Pr. 70 Special regenerative brake duty value on your Mitsubishi Electric Inverter, a prealarm will appear. To address this, increase the deceleration time and check the settings for Pr. 30 Regenerative function selection and Pr. 70 Special regenerative brake duty.
What causes electronic thermal relay function prealarm on Mitsubishi Electric FR-F700 Inverter?
If the integrating value of Pr. 9 Electronic thermal O/L relay reaches or exceeds 85% of the preset level on your Mitsubishi Electric Inverter, a prealarm will appear. You can reduce the load weight or the number of operation times, or set an appropriate value in Pr. 9 Electronic thermal O/L relay.
How to solve regenerative overvoltage shut-off during deceleration or stop on Mitsubishi Electric FR-F700 Inverter?
If regenerative energy causes the internal main circuit DC voltage to reach or exceed the specified value during deceleration or stop, the protective circuit in your Mitsubishi Electric Inverter activates. Increase the deceleration time to resolve this issue.
What causes regenerative overvoltage shut-off during constant speed in Mitsubishi Electric Inverter?
If regenerative energy causes the inverter's internal main circuit DC voltage to exceed the specified value during constant speed operation, the protective circuit in your Mitsubishi Electric Inverter will activate. Ensure the load remains stable or use a brake unit or power regeneration common converter (FR-CV) if necessary.
How to prevent regenerative overvoltage shut-off during acceleration on Mitsubishi Electric FR-F700?
If regenerative energy causes the inverter's internal main circuit DC voltage to reach or exceed the specified value during acceleration, the protective circuit in your Mitsubishi Electric Inverter will activate. Decrease the acceleration time to prevent this.
What to do if Mitsubishi Electric FR-F700 has overcurrent shut-off during deceleration or stop?
If the Mitsubishi Electric Inverter output current exceeds approximately 170% of the rated current during deceleration (other than acceleration or constant speed), the protective circuit activates. Increase the deceleration time to resolve this.
How to fix Mitsubishi Electric FR-F700 Inverter overcurrent shut-off during constant speed?
If the Mitsubishi Electric Inverter output current reaches or exceeds approximately 170% of the rated current during constant speed operation, the protective circuit activates. To prevent this, keep the load stable.
What causes inverter overload shut-off on Mitsubishi Electric Inverter?
If a current not less than 110% of the rated output current flows and overcurrent shut-off does not occur (170% or less) in your Mitsubishi Electric Inverter, reduce the load weight.
