validation
Non-volatile An error of the parameter data
memory data error stored in the non-volatile
(parameter) memory has been detected.
Non-volatile An error of the control data
memory data error stored in the non-volatile
(control data) memory has been detected.
Output read-back A discrepancy of an output
error read-back value and an output
value was detected.
Action
There may be an influence from noise or a hardware failure. If
the same error occurs again even after measures have been
taken against noise, the module may be in failure. Please
consult your local Mitsubishi representative.
• Match the ON timing of the external power supply with the
ON timing of the module power supply.
• Review the connected devices, wiring, and voltage.
• There may be an influence from noise of external wiring
(such as power supply part and I/O signal part). Take
measures to reduce noise.
• If the same error occurs again, the module may be in
failure. Please consult your local Mitsubishi representative.
• Check the connection status of the extension module.
• If the module is connected properly, there may be an
influence from noise or a hardware failure. If the same error
occurs again even after measures have been taken against
noise, the module may be in failure. Please consult your
local Mitsubishi representative.
There may be an influence from noise or a hardware failure. If
the same error occurs again even after measures have been
taken against noise, the module may be in failure. Please
consult your local Mitsubishi representative.
Check whether the extension module connected is
connectable to this product. If the module is connectable,
there may be an influence from noise or a hardware failure. If
the same error occurs again even after measures have been
taken against noise, the module may be in failure. Please
consult your local Mitsubishi representative.
• Restart the module.
• If the same error occurs again, the module may be in
failure. Please consult your local Mitsubishi representative.
• The module will recover from this error by initializing
parameters by using Parameter area initialization
command. In such a case, parameters are required to be
set again by users.
• If the same error occurs again, the module may be in
failure. Please consult your local Mitsubishi representative.
• Check parameters again and perform the safety module
validation.
• If the same error occurs again, the module may be in
failure. Please consult your local Mitsubishi representative.
• Match the ON timing of the external power supply with the
ON timing of the module power supply.
• Review the connected devices and wiring.
• Check that 24V is supplied to the external power supply
using a tester.
• Check that the external connection is not overloaded.
• When the connected devices and wiring have no errors,
there may be an influence from noise or a hardware failure.
Take measures to reduce noise.
• If the same error occurs again, the module may be in
failure. Please consult your local Mitsubishi representative.
