CH1 Set value check code
The check result of whether the set digital value is within the setting range can be checked.
The target values are 'CH1 Digital value' (Un\G460) in the normal output and the wave data to be output in the wave output.
When a digital value out of the setting range is written, one of the following check codes is stored.
Check code
000FH
00F0H
00FFH
Once the check code is stored, the code is not reset even when the digital value falls within the setting range.
To reset the check code, rewrite the digital value to a value within the setting range and turn on and off 'Error clear request'
(YF).
When the scaling function is used, the value of 'CH1 Digital value' (Un\G460) which has undergone a scale conversion is
checked. Note that some errors may be observed in the target digital value for a check code to be stored due to the
calculation error of scale conversion when a scale-converted value exceeds the setting range.
When a check code is stored in the wave output, the address of the wave data which is out of the setting range can be
checked with 'CH1 Wave output digital value outside the range Address monitor' (Un\G440 to Un\G441).
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
CH Setting value check code
CH Setting value check code (When the Q
compatible mode function is used)
CH1 Wave output status monitor
The wave output status can be checked.
Monitor value
0H
1H
2H
3H
Only when the wave output function is used and the operation mode is normal mode, a value is stored in the area. Otherwise,
0 is stored.

Description
A digital value exceeding the setting range has been written.
A digital value falling short of the setting range has been written.
A digital value falling short of the setting range and a digital value exceeding the setting range have been written.
This check code may be stored when a check code is not reset.
