CH1 Constant for wave output conversion cycle
For the above setting, the wave pattern output cycle is as follows (when D/A conversion is enabled only for CH1).

Wave output conversion cycle
The wave pattern conversion cycle is calculated using the following formula.
Conversion cycle
=
(s)
The wave output function allows you to set the conversion cycle by setting 'CH1 Constant for wave output conversion cycle'
(Un\G531). The conversion cycle of the current wave output can be examined using 'CH1 Wave output conversion cycle
monitor' (Un\G432, 433).

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
For the above setting, the conversion cycles for the channels are as follows.
• CH1: 80  4  1 = 320 (s)
• CH2: 80  4  2 = 640 (s)
• CH3: 80  4  3 = 960 (s)
• CH4: 80  4  4 = 1280 (s)
With this conversion cycle, D/A conversion is executed and the analog values are output.
