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

List of error codes

If an error occurs during operation, an analog output 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 an analog output module are classified into minor and 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: An error such as hardware failure. The D/A conversion does not continue. (3000H to 3FFFH)
The following table lists the error codes that may be stored.
: Indicates the number of the channel where an error has occurred. It represents one of numerical values 0 to 3, which
correspond to CH1 to CH4.
(CH1: 0, CH2: 1, CH3: 2, CH4: 3)
 in error code: Indicates the interrupt setting corresponding to the error (0: setting 1 to F: setting 16).

Description and cause
There is no error.
The number of the offset/gain settings has
exceeded the guaranteed maximum number.
A value other than 0 or 1 was set in 'Interrupt factor
transaction setting' (Un\G200 to 215).
A value other than 0 to 4 was set in 'Condition target
setting' (Un\G232 to 247).
A value other than 0 to 4 was set in 'Condition target
channel setting' (Un\G264 to 279).
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 Range
setting.
• For normal output
A value out of the range is set for the CH Digital
value.
• For wave output
A value out of the setting range was set for part of
'wave data registry area' (Un\G10000 to
Un\G89999) used for the channel of wave-output-in-
progress.
A value out of the range is set in CH HOLD
setting.
A value other than 0 and 1 is set in CH Scaling
enable/disable setting.
CH Scaling upper limit value and CH Scaling
lower limit value are set as the scaling upper limit
value = the scaling lower limit value.
A value other than 0 to 2 was set in CH Warning
output setting.
A value not meeting the following condition was set
for the CH Warning output upper limit value or
CH Warning output lower limit value.
Upper limit value > Lower limit value
A value other than 0 or 1 was set in CH Rate
control enable/disable setting.
A value other than 0 to 64000 was set for the CH
Increase digital limit value or CH Decrease digital
limit value.
Corrective action

Though any further setting of offset/gain values
is performed, the setting value will not be
guaranteed.
Retry to set 0 or 1 in 'Interrupt factor transaction
setting' (Un\G200 to 215).
Retry to set a value of 0 to 4 in 'Condition target
setting' (Un\G232 to 247).
Retry to set a value of 0 to 4 in 'Condition target
channel setting' (Un\G264 to 279).
For the offset/gain setting, write the setting
value only once per setting.
Set CH Range setting to the value within the
range again.
Retry to set a proper value for the CH Digital
value.
Correct the corresponding data in 'wave data
registry area' (Un\G10000 to Un\G89999) being
used for the channel where the error occurred,
to a value within the setting range.
Retry to set a proper value for the CH HOLD
digital value.
Set CH Scaling enable/disable setting to 0 or
1.
Set CH Scaling upper limit value and CH
Scaling lower limit value as the scaling upper
limit value  the scaling lower limit value.
Retry to set CH Warning output setting to 0 to
2.
Retry to set the CH Warning output upper limit
value and CH Warning output lower limit
value so that the condition "upper limit value >
lower limit value".
Retry to set CH Rate control enable/disable
setting to 0 or 1.
Retry to set a value of 0 to 64000 for the CH
Increase digital limit value or CH Decrease
digital limit value.
