• For indefinite repetition
Any digital input value at the wave pattern end point is not output as analog data.
A wave pattern that is repeatedly
output in an analog value
The digital input values of
the start point and the end
point are the same *1
1 cycle
*1 The wave pattern output cycle is calculated using the following formula.
Wave pattern output cycle = (Wave output conversion cycle)  (Wave pattern data points -1)
For details on the wave output conversion cycle, refer to the following.

Setting item
CH1 D/A conversion enable/disable setting
CH1 Wave pattern data points setting
CH1 Wave pattern output repetition setting
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).

■If the start and end point digital input values are different
The wave pattern end point is directly output as analog data. Regardless of the setting in 'CH1 Wave pattern output repetition
setting' (Un\G530), the set wave patterns are consecutively output as analog data.

The digital input value of the end point
and the digital input value of the next
start point are successively output in analog
For the case where the wave pattern is
repeatedly output for a limited number of times,
the wave pattern is output for the number of
times specified in Wave pattern output repetition
setting, and then the value is output in analog
according to the setting in Output setting during
wave output stop.

The start point data of the next iteration always comes
after the end point data, not to let the end point data be
output, to seamlessly connect the wave.
