3.5 List of Error Codes
Action
• Check the settings for connection with the external device.
• Check the operation of the external device or switching hub.
• Since there may be congestion of packets on the line, send data after a
certain period of time.
• Check if the connection cable is disconnected.
• Check that there is no connection failure with the switching hub.
• Execute the communication test, and if the test was completed with an
error, take corrective action.
Change the IP address of devices with a duplicated IP address.
Check the error of the CPU module and take action using the module
diagnostics of the engineering tool.
Lower the transient transmission usage frequency, and retry the operation.
The hardware failure of the CPU module may have been occurred. Please
consult your local Mitsubishi representative.
Check and correct the IP addresses.
Check the detailed information of the error by executing module diagnostics
using the engineering tool, and write the displayed parameter. If the same
error occurs again, the possible cause is a hardware failure of the module.
Please consult your local Mitsubishi representative.
Check the detailed information of the error by executing module diagnostics
using the engineering tool, and correct the parameter setting corresponding
to the displayed parameter No..
• Take measures to reduce noise.
• Reset the CPU module, and run it again. If the same error occurs again
even after taking the above, the possible cause is a hardware failure of the
module, base unit, or extension cable. Please consult your local Mitsubishi
representative.
• Take measures to reduce noise.
• Reset the CPU module, and run it again. If the same error occurs again
even after taking the above, the possible cause is a hardware failure of the
module, base unit, or extension cable. Please consult your local Mitsubishi
representative.
Check the detailed information on module diagnostics of the engineering tool
and set the value of "Communication Period Setting" of the slave station
under "Basic Settings" within 16ms.
• Check the detailed information of the error by executing module
diagnostics using the engineering tool, and correct the parameter setting of
the master station corresponding to the displayed parameter No..
• If the same error occurs again, the possible cause is a hardware failure of
the module. Please consult your local Mitsubishi representative.
• Check the Announce frame send cycle parameter setting value of the
device operating as the grandmaster. When the Motion module is
operating as the grandmaster, reset the CPU module, and run it again.
• If the same error occurs again even after taking the above measure, the
possible cause is a hardware failure of the module. Please consult your
local Mitsubishi representative.
