What causes a receive data error on a Mitsubishi Electric Controller?
A receive data error on your Mitsubishi Electric Controller means that the wrong data was received from the inverter. To correct this, check the wiring and look for the presence of noise.
Why does my Mitsubishi Electric MELSEC iQ-F show error CFE8H?
The Mitsubishi Electric Controller displays error code CFE8H when there is no response from a slave station. To resolve this, check the slave station disconnection detection setting in the master station parameter (Network Configuration Settings). Also, verify the existence status of the slave station in the network, and inspect the disconnected slave station. Finally, take measures to reduce noise.
What to do if Mitsubishi Electric Controller shows error CFE1H?
If your Mitsubishi Electric Controller shows error CFE1H, it means an unusable number of occupied stations has been specified from the master station. You should check the number of occupied stations setting in the master station parameter (Network Configuration Settings).
What to do if the Mitsubishi Electric MELSEC iQ-F Controller inverter does not start in Network operation mode?
If the Mitsubishi Electric Controller inverter fails to start in Network operation mode, verify that the inverter starting program is running and that it has been written correctly. Additionally, ensure that Pr.338 Communication operation command source is not set to External.
What does station number error mean on Mitsubishi Electric MELSEC iQ-F Controller?
A station number error on the Mitsubishi Electric Controller means that an unspecified station responded. To resolve this, check the parameter settings.
What causes a mode error on a Mitsubishi Electric MELSEC iQ-F?
A mode error on the Mitsubishi Electric Controller occurs when a parameter was written in a mode other than computer link operation mode, or while the inverter was operating. Check the operation mode and operation command source, such as Pr.77, Pr.79, and Pr.340, of the inverter.
How to resolve issues when unable to set some properties on Mitsubishi Electric MELSEC iQ-F?
If you find that you are unable to set certain properties on your Mitsubishi Electric Controller, it may be because the property is defined as unchangeable or unwritable according to the BACnet standard. Check the BACnet standard to confirm.
How to fix L ER LED turned on in Mitsubishi Electric Controller?
If the L ER LED is on, ensure that the Ethernet cables meet the standard. You might need to use an Ethernet cable that conforms to the standard. Also, make sure that the station-to-station distance is within the specified range. Replace any disconnected Ethernet cables. Check if the industrial switch is operating normally; use a standard-compliant switch and try power cycling it. Finally, check for any sources of noise near the module or cables and relocate them if necessary.
Why does my Mitsubishi Electric Controller show error CFE9H?
The Mitsubishi Electric Controller shows error CFE9H because the slave station of the same IP address has existed in the same network address. To fix this, check the slave station where the error occurred.
Why does my Mitsubishi Electric Controller show error CFD0H?
The Mitsubishi Electric Controller shows error CFD0H because the port No. (61450) used in CC-Link IE Field Network Basic has already been used. To solve this, check the port No. used in the Ethernet function.
