What does calibration error mean on Mitsubishi Inverter?
A calibration error on the Mitsubishi Inverter indicates that the analog input bias and gain calibration values are too close. Check the settings of C3, C4, C6, and C7 (calibration functions).
What causes stall prevention tripping on a Mitsubishi Inverter?
If the Mitsubishi Inverter's output frequency falls to 1Hz due to stall prevention and remains there for 3 seconds, a fault appears, and the inverter trips. Reduce the load weight to prevent this.
How to unlock password on Mitsubishi Inverter?
To unlock a password-locked Mitsubishi Inverter, enter the password in Pr. 297 Password lock/unlock before operating.
What does regenerative brake prealarm mean on a Mitsubishi 700 Inverter?
The regenerative brake prealarm appears if the regenerative brake duty reaches or exceeds 85% of the Pr. 70 Special regenerative brake duty value on your Mitsubishi Inverter. To resolve this, increase the deceleration time.
How to troubleshoot output phase loss on a Mitsubishi Inverter?
Output phase loss on a Mitsubishi Inverter occurs if one of the three phases (U, V, W) on the inverter's output side is lost during operation. Ensure the cables are properly wired.
Why does my Mitsubishi Inverter show a write error during operation?
A write error during operation on a Mitsubishi Inverter happens when parameter writing is performed during operation with a value other than "2" set in Pr. 77, and the STF (STR) is ON. To solve this, set "2" in Pr. 77 or stop the operation before making parameter settings.
What to do if Mitsubishi Inverter shows input phase loss?
The Mitsubishi Inverter trips if Pr. 872 Input phase loss protection selection is set to valid (=1) and one phase of the three-phase power input is lost. Ensure the cables are properly wired and repair any breaks in the cable.
What does stall prevention (overcurrent) mean on a Mitsubishi 700 Inverter?
During acceleration, if the Mitsubishi Inverter's output current exceeds the stall prevention operation level (Pr. 22 Stall prevention operation level, etc.), the function stops the frequency increase until the overload current decreases. This prevents the inverter from an overcurrent trip.
What causes a motor overload trip on a Mitsubishi 700 Inverter?
The Mitsubishi Inverter's electronic thermal relay function detects motor overheat, which can be caused by overload or reduced cooling during constant-speed operation. To resolve this, reduce the load weight.
How to fix a write disable error on a Mitsubishi Inverter?
A write disable error on your Mitsubishi Inverter can occur due to several reasons. First, it could be because you're trying to change a parameter when Pr. 77 (Parameter write selection) is set to disable writing. Check the setting of Pr. 77 to resolve this. Second, the frequency jump setting range might be overlapping; review the settings of Pr. 31 to Pr. 36 (frequency jump). Finally, the PU and inverter may not be communicating correctly; check their connection.
