CH1 Setting 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 mode and the wave data to be output in the wave
output mode.
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'
(Un\G70, b15).
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 (in FX3 allocation
mode function)
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 upper limit of the setting range has been written.
A digital value below the lower limit of the setting range has been written.
A digital value falling short of the setting range and a digital value exceeding the upper limit setting range have been
written.
This check code may be stored when a check code is not reset.
