data out of the range is set.
Action
• The module will automatically recover immediately
after the error occurs.
• Check that no moderate error caused by the
parameter setting has occurred on the module using
the ERR. LED of the module and the error history. If
an error has occurred, eliminate the cause.
• If the same error occurs again even after "Safety
module validation" is executed in no error state, the
module may be in failure. Please consult your local
Mitsubishi representative.
• Review the connected devices, wiring, and voltage.
• Correct the module parameter settings and module
configuration.
• When the parameters are set again and the
parameter setting has succeeded, the module will
recover from this error.
