List of Error Codes

When an error occurs during operation, the D/A converter module stores an error code in 'Latest error code' (Un\G0) of the
buffer memory. In addition, 'Error flag' (XF) turns on. Turning on 'Error clear request' (YF) allows clearing of the error code of
'Latest error code' (Un\G0), and turning off of 'Error flag' (XF). The error code is also cleared by turning on and off 'Operating
condition setting request' (Y9).
Error codes of the D/A converter module are classified in minor errors or moderate errors.
• Minor error: An error generated by an incorrect setting of a program or parameter. The D/A conversion continues with the
parameter setting before the change. (1000H to 1FFFH)
• Moderate error: An error such as hardware failure. The D/A conversion does not continue. (2000H to 2FFFH, 3000H to
3FFFH)
The following table lists the error codes that may be stored.
 in an error code: This symbol indicates the number of the channel where an error has occurred. A numerical value of 0 to 3
is used to correspond to CH1 to 4.
(CH1: 0, CH2: 1, CH3: 2, CH4: 3)

3.4 List of Error Codes
Description and cause
There is no error.
The number of the offset/gain settings has exceeded
the guaranteed maximum number.
Offset/gain values cannot be restored with the
module-specific backup parameter.
The module-specific backup parameter was not
created.
Interrupt factor generation setting [n] is set to a value
other than Interrupt resend request (0) and No
interrupt resend request (1).
 indicates the interrupt setting related to the error
as follows:
0: Setting 1 to F: Setting 16
Condition target setting [n] is set to a value outside
the range.
 indicates the interrupt setting related to the error
as follows:
0: Setting 1 to F: Setting 16
Condition target channel setting [n] is set to a value
outside the range.
 indicates the interrupt setting related to the error
as follows:
0: Setting 1 to F: Setting 16
• In offset/gain setting mode
• In wave output mode
• When the module is set as an inter-module
synchronization target
The G(P).OGSTOR instruction has been executed in
above cases.
The G(P).OGSTOR instruction has been executed
continuously or a set value has been continuously
written to the flash memory 26 times or more in the
offset/gain setting.
The G(P).OGSTOR instruction has been executed
on a module of the model different from the one on
which the G(P).OGLOAD instruction was executed.
Or the G(P).OGSTOR instruction has been executed
ahead of the G(P).OGLOAD instruction.
Action

Any further setting of offset/gain values may not be
reflected correctly.
The module-specific backup parameter file may be
damaged. Readjust the user range.
Check the free space on the data memory of the
control CPU and the SD memory card, and recreate
a module-specific backup parameter.
For how to create module-specific backup
parameters, refer to the following.
Page 107 Creating and updating a module-
specific backup parameter
Set Interrupt factor generation setting [n] to Interrupt
resend request (0) or No interrupt resend request
(1).
Set Condition target setting [n] to a value within the
range of Disable (0) to External power supply
READY flag (X7) (4).
Set Condition target channel setting [n] to a value
within the range of All channels (0) to CH4 (4).
Execute the G(P).OGSTOR instruction in normal
output mode.
For the G(P).OGSTOR instruction, execute it only
once per module. For the offset/gain setting, write
the set value only once per setting.
Execute the G(P).OGLOAD and G(P).OGSTOR
instructions on a module of the same model.
Moreover, execute the G(P).OGLOAD instruction on
the module from which data is saved, and then
execute the G(P).OGSTOR instruction on the
module to which the data is restored.
