Error Code List

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) clears the error code in 'Latest error
code' (Un\G0), and 'Error flag' (XF) turns off.
Error codes of the D/A converter module are classified in minor errors or moderate errors.
• Minor error: This error is caused by the setting failure of programs and parameters. The D/A conversion continues with the
parameter setting before the change. (1000H to 1FFFH)
• Moderate error: Hardware failures and errors at the execution of the inter-module synchronization function are included.
The D/A conversion do not continue. (2000H to 2FFFH, 3000H to 3FFFH)
The following table shows the error codes stored.
 in error codes: Indicates the channel number of a generated error. A numerical value of 0 to 7 is used to correspond to
channel 1 to 8.
(CH1: 0, CH2: 1, CH3: 2, CH4: 3, CH5: 4, CH6: 5, CH6: 5, CH7: 6, CH8: 7)
 in error codes: Indicates the interrupt setting corresponding to an error (0: Setting 1 to F: Setting 16).

3.4 Error Code List
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 has not
been created.
A value other than 0 to 1 is set in Interrupt factor
generation setting [n].
A value other than 0 to 4 is set in Condition target
setting [n].
A value other than 0 to 8 (for R60DA4, 0 to 4) is set
in Condition target channel setting [n].
• Offset/gain setting mode
• Wave output mode
• The module is set as a target for the inter-module
synchronization.
The G(P).OGSTOR instruction is executed in one of
the cases above.
The G(P).OGSTOR instruction is continuously
executed.
In the offset/gain setting, a setting value has been
written to the flash memory more than 25 times
consecutively.
The G(P).OGSTOR instruction has been executed
on a module different from the one on which the
G(P).OGLOAD instruction was executed.
The G(P).OGSTOR instruction has been executed
ahead of the G(P).OGLOAD instruction.
A value outside the range is set in CH Range
setting.
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 88 Backing up, Saving, and Restoring
Offset/Gain Values
Set Interrupt factor generation setting [n] to 0 or
1.
Set Condition target setting [n] to 0 to 4.
Set Condition target channel setting [n] to 0 to 8
(for R60DA4, 0 to 4).
Execute the G(P).OGSTOR instruction in the
normal mode.
For the G(P).OGSTOR instruction, execute it
only once per module.
Write the setting value into the flash memory
only once for each offset/gain setting.
Execute the G(P).OGLOAD and G(P).OGSTOR
instructions on the same module.
Execute the G(P).OGLOAD instruction on the
module whose data is to be restored, and
execute the G(P).OGSTOR instruction on the
module to which the data is restored.
Set any of the following values in CH Range
setting:
R60DA4: 0 to 4, E, F (hexadecimal)
R60DAV8: 0, 2 to 4, E (hexadecimal)
R60DAI8: 0, 1, F (hexadecimal)
