What to do if Mitsubishi Inverter has a firmware-generated error?
If you receive a firmware-generated error on your Mitsubishi Inverter, record the error code blinking pattern and contact technical support for further assistance.
How to unlock operation panel on Mitsubishi 700 Inverter?
To release the operation panel lock on the Mitsubishi Inverter, press the lock button for 2 seconds.
What to do if Mitsubishi 700 Inverter shows overload trip error?
If the temperature of the output transistor element exceeds the protection level when a current not less than the rated inverter current flows (200% or less), the electronic thermal relay activates, stopping the Mitsubishi Inverter output. To resolve this, try increasing the acceleration/deceleration time or adjusting the torque boost setting.
Why is my Mitsubishi Inverter showing an undervoltage error?
If the Mitsubishi Inverter's power supply voltage decreases, the control circuit won't function normally. Check the power supply system equipment, including the power supply itself, to resolve this issue.
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.
What causes Studio to fail accessing the file system of Mitsubishi 700?
If Studio cannot access the file system of your Mitsubishi Inverter, the card’s file system may be corrupt. Format the card’s file system and then restore the configuration. If the card cannot be formatted, please contact technical support for instructions to manually format the card’s file system.
Why I am unable to control the Mitsubishi 700 Inverter via network communications?
If you're unable to control the Mitsubishi Inverter via network communications, ensure the inverter is set to NET mode. The inverter will reject command and parameter write requests from the network if it is not in NET mode. If you are using the inverter’s terminal contacts, refer to the inverter’s instruction manual to determine the appropriate behavior and priority. Also, try clearing all parameter settings to default and reconfiguring the parameters.
What to do if Studio cannot discover the Mitsubishi Inverter card?
If Studio cannot discover the Mitsubishi Inverter card, first confirm that the card is running normally and connected via USB or to the local Ethernet network (connecting via USB is preferable). Check that the module and network status LEDs blink the green/red startup sequence when power is initially applied. Also, add the Studio as an exception to your computer’s firewall, add UDP port 4334 as an exception to the firewall, or temporarily disable the computer’s firewall.
How to resolve a mode designation error on a Mitsubishi Inverter?
A mode designation error occurs if a parameter setting is attempted in the External or NET operation mode with Pr. 77 not set to "2" on your Mitsubishi Inverter. First, ensure the operation mode is set to PU operation mode. Then, set the operation mode to "PU operation mode" before making parameter settings.
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.
