CH1 Constant for wave output conversion cycle
Wave
Set a constant to determine the conversion cycle (multiply the conversion speed). Use the value set in this area to set the
conversion cycle in accordance with the following conditions.
• Conversion cycle = Conversion speed (20s)  Number of D/A conversion enabled channels  Constant for wave output
conversion cycle
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
CH Constant for wave output conversion cycle
■Setting range
• The setting range is from 1 to 5000.
• In the channel where a value out of the setting range is set, a setting range error for Constant for wave output conversion
cycle (error code: 1D7H) occurs. The wave output does not start.
■Enabling the setting
Turn on and off 'Operating condition setting request' (Y9) to enable the setting.
■Default value
The default value is 1 for all channels.
CH1 Range setting
Common
This area is for setting an output range.
Output range
4 to 20mA
0 to 20mA
1 to 5V
0 to 5V
-10 to 10V
User range setting (voltage)
User range setting (current)
• If a value other than the above is set, a range setting range error (error code: 190H) occurs.
• To prevent a sudden change of the analog output, a range change denial alarm during analog output in CH (alarm code:
0C0H) occurs when the range switching is attempted to be executed with the D/A conversion and output enabled. Thus,
the range switching is not executed. To execute the range switching, turn off 'CH1 Output enable/disable flag' (Y1).
• The user range cannot be used in the wave output mode. If a user range is set in the wave output mode, a user range
specification error with the wave output function used (error code: 1D1H) occurs, and the wave output is not started.
• The output range cannot be changed for a channel where D/A conversion is disabled. To change the output range, set 'CH1
D/A conversion enable/disable setting' (Un\G500) to D/A conversion enable (0), turn off 'CH1 Output enable/disable flag'
(Y1), and turn on and off 'Operating condition setting request' (Y9).
