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

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
With the above setting, the output cycle of a wave pattern becomes as follows. (When the D/A conversion is enabled only for
CH1)

For the case where the wave pattern is repeatedly
output a limited number of times, the wave pattern
is output a number of times specified in Wave
pattern output repetition setting, and then the value
is output according to the setting in Output setting
during wave output stop.

Wave can be combined seamlessly by not outputting end point
data because the end point data overlaps with the start point
data of the next iteration.
