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 to do if Mitsubishi Electric MELSEC iQ-F Controller operation mode does not switch to the Network operation mode?
If the Mitsubishi Electric Controller operation mode does not switch to the Network operation mode, check that the Ethernet cable is correctly installed, looking for contact faults or breaks in the cable. Also, ensure that the inverter is in the External operation mode, that the operation mode switching program is running, and that the operation mode switching program has been written correctly.
Why does my Mitsubishi Electric Controller show error CFC0H?
The Mitsubishi Electric Controller shows error CFC0H because it is unable to execute cyclic transmission due to multiple master stations existing in the same network address. To fix this, check the existence status of master stations in the network.
Why does my Mitsubishi Electric Controller show error CFC8H?
The Mitsubishi Electric Controller shows error CFC8H because it is unable to execute cyclic transmission because a slave station controlled by another master station exists. To resolve this, check the existence status of master stations in the network and check the slave station where the error occurred.
Why does my Mitsubishi Electric MELSEC iQ-F Controller show error CFC1H?
The Mitsubishi Electric Controller shows error CFC1H because it is unable to execute cyclic transmission due to an error occurring in cyclic transmission. To address this, take measures to reduce noise. If the same error appears again, contact your local Mitsubishi representative.
Why does my Mitsubishi Electric MELSEC iQ-F Controller show error CFC9H?
The Mitsubishi Electric Controller shows error CFC9H because it is unable to execute cyclic transmission because a slave station with the same IP address exists in the same network address. To resolve this, check the existence status of slave stations in the network and check the slave station where the error occurred.
What to do if Mitsubishi Electric MELSEC iQ-F is unable to synchronize the time with another BACnet device?
If you're having trouble synchronizing the time with another BACnet device on your Mitsubishi Electric Controller, there are a couple of things to check. First, ensure that a program has been created to change the time of the FX5 CPU module at the received time; if not, create the program. Additionally, verify that the Ethernet module is configured as a destination for the other BACnet device; configure it if necessary.
Why does my Mitsubishi Electric MELSEC iQ-F Controller show error CFE0H?
The Mitsubishi Electric Controller shows error CFE0H because the cyclic transmission was executed for a slave station controlled by another master station. To resolve this, check the existence status of master stations in the network and check the slave station where the error occurred.
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 CFD1H?
The Mitsubishi Electric Controller shows error CFD1H because an invalid value has been set in the subnet mask. To correct this, check the parameter setting.
