List Of Error Codes - Mitsubishi Electric MELSEC iQ-F FX5 User Manual

■The digital output value is not converted to an expected value
Check item
Check whether the input type/input range setting are correct.
Check whether the offset/gain setting is correct.
Check whether average processing specification is correct.
Is an external input being made to a conversion disabled channel?
■Digital output value varies
Check item
Check whether a conversion method other than sampling processing is set.
■Conversion completed flag does not turn on
Check item
Check whether all channels are set to be conversion disabled.

List of error codes

If an error occurs during operation, a multiple input module stores the error code into 'Latest error code' (Un\G0) of the buffer
memory. In addition, 'Error flag' (Un\G69, b15) turns on. Turning on 'Error clear request' (Un\G70, b15) clears the error code in
'Latest error code' (Un\G0) and turns off 'Error flag' (Un\G69, b15).
Error codes of a multiple input module are classified in minor errors or moderate errors.
• Minor error: This error is caused by the setting failure of programs and parameters, and after eliminating the error cause,
each function normally executes. (1000H to 1FFFH)
• Moderate error: Hardware failures. The A/D conversion, and temperature conversion do not continue. (3000H to 3FFFH)
The following table lists the error codes that may be stored.
: This symbol indicates the number of the channel where an error has occurred. A numerical value of 0 to 7 is used to
correspond to CH1 to 8.
(CH1: 0, CH2: 1, CH3: 2, CH4: 3, CH5: 4, CH6: 5, CH7: 6, CH8: 7)
: For what this symbol indicates, refer to Description and cause of error.

3.10 Troubleshooting
Corrective action
Check the setting of input type, and input range from the "Module parameter
setting" screen of GX Works3.
If the setting range is not correct, set input range from "Module parameter
setting" screen again.
Check that the offset/gain setting is correct. If the user range setting is used,
change to the factory shipment setting, and check that the conversion is
performed.
When the conversion is correct, perform the offset/gain setting again.
Check the setting of average processing specification from the "Module
parameter setting" screen of GX Works3.
If the setting is different from the average processing you want to use, reset
the average processing specification from the "Module parameter setting"
screen.
Do not input to a conversion disabled channel from an external device.
Corrective action
Check the setting of average processing specification from the "Module
parameter setting" screen of GX Works3.
Review the setting of average processing specification and check the state of
variation of 'CH1 Digital output value' (Un\G400) again.
Corrective action
Check the setting of input type with GX Works3.
If there is no channel other than conversion disabled, please set the input type
setting to one other than "Conversion disabled" for one or more channels from
GX Works3 or sequence program.
Description and cause
There is no error.
The number of the offset/gain settings has
exceeded the guaranteed maximum number.
In 2CH conversion mode, CH used for
conversion enabled CH number is out of
combination range.
The setting value has been continuously written
to the flash memory 26 times or more in the
offset/gain setting.
• A value out of the range is set in CH Input
type/Range setting.
• A value out of the range is set in CH Range
setting (Offset/gain setting).
Corrective action

Any further setting of offset/gain values may not be
reflected correctly.
Reconfigure CH to the conversion enabled with the
correct combination for conversion enabled CH
number.
For the offset/gain setting, write the setting value
only once per setting.
• Set CH Input type/Range setting to the value
within the range again.
• Set 0 or 1 in CH Range setting (Offset/gain
setting).
