5.5 List of Error Codes
Action
Check the following.
• Is a correct node ID assigned to the NMT slave?
• Are values to be set correct?
• Is the NMT slave running?
• NMT slave state
• Is the boot time setting value sufficient?
• Write this module extension parameters into the
CPU module.
• Check and correct the settings for extension
parameters and rewrite them to the CPU module.
• Exchange the module if an error occurs after
rewriting them.
Check the value set for the parameter. The value may
become different from the set value because it can be
overwritten by the RJ71CN91 when a parameter error
occurs.
Save parameters in the flash ROM again, and restart
the RJ71CN91.
If the same error is displayed again, please consult
your local Mitsubishi representative.
• Take measures to reduce noise.
• Reset the CPU module, and run it again. If the error
occurs again even after taking the above, the
possible cause is a hardware failure of the
RJ71CN91, base unit, or extension cable. Please
consult your local Mitsubishi representative.
