Wave output conversion cycle
The wave output conversion cycle is calculated by the following formula.
• Conversion cycle (s) = Conversion speed (20s)  Number of D/A conversion enabled channels  "Constant for wave
output conversion cycle"
In the wave output function, the conversion cycle can be set by setting 'CH1 Constant for wave output conversion cycle'
(Un\G531). The conversion cycle of the current output wave can be checked in 'CH1 Wave output conversion cycle monitor'
(Un\G432, Un\G433).

Setting item
D/A conversion enable/disable setting
CH1 Constant for wave output conversion cycle
CH2 Constant for wave output conversion cycle
CH3 Constant for wave output conversion cycle
CH4 Constant for wave output conversion cycle
The following figure shows the conversion cycle of each channel with the above settings.
• CH1: 80s
• CH2: 160s
• CH3: 240s
• CH4: 320s
D/A conversion is performed with this conversion cycle, and an analog value is output.
