■Default value
The default value is 0 for all channels.
CH1 Range setting
This area is for setting the output range.
Setting value
0003H
0002H
0005H
0006H
0000H
0007H
000DH
000EH
If a value other than the above is set, a range setting range error (error code: 190H) occurs.
If the range switching is attempted with the D/A conversion and D/A output enabled for the purpose of preventing a sudden
change in the analog output, CH Under-output range change denial alarm (alarm code: 0C0H) occurs and the range
switching is not executed. To execute the range switching, turn off 'CH1 Output enable/disable flag' (Un\G70, b1).
The user range cannot be used when the wave output function is used. Even within the setting range in the above table, when
the user range is set while the wave output function is used, a user range specification error in wave output mode (error code:
1D1H) occurs and the wave output does not start.
■Buffer memory address
The following shows the buffer memory address of this area.

■Enabling the setting
Turn on and off 'Operating condition setting request' (Un\G70, b9) to enable the setting.
Range setting [FX3 allocation mode]
When the FX3 allocation mode function is used, this area is for setting the output range.
The setting contents in FX3 allocation mode are as follows.
b15 ... b12 b11

If a value other than the above is set, a range setting range error (error code: 190H) occurs.
If the range switching is attempted with the D/A conversion and D/A output enabled for the purpose of preventing a sudden
change in the analog output, CH. Under-output range change denial alarm (alarm code: 0C0H) occurs and the range
switching is not executed. To execute the range switching, turn off 'CH1 Output enable/disable flag' (Un\G70, b1).
