Wave pattern output count
The wave pattern can be output repeatedly according to the setting of 'CH1 Wave pattern output repetition setting' (Un\G530).
Set the output count within 1 to 32767. The wave pattern also can be output in analog repeatedly and unlimitedly by setting
'CH1 Wave pattern output repetition setting' (Un\G530) to -1.
Ex.
When the wave pattern output count is set to three
Analog output
Wave pattern
(1) The wave pattern is output repeatedly three times.
(2) After the wave pattern is output three times, the wave output stops and the data set in 'CH1 Output setting during wave output stop (Un\G524)' is output in
analog.
The following section describes "repeat control" in which the same wave pattern is output repeatedly from the D/A converter
module.
■When the digital values are same for the start point and the end point
An end point of a wave pattern overlaps with the start point of the wave pattern of the next iteration in the D/A converter
module's processing; therefore, the end point is not output in analog. The analog output of the wave pattern end point varies
as follows depending on the setting of 'CH1 Wave pattern output repetition setting' (Un\G530).
• Limited repetition:
When a value of 2 to 32767 is set to 'CH1 Wave pattern output repetition setting' (Un\G530), the digital value of the end point
is not output in analog till the wave pattern of the final iteration output. After the digital value of the end point is output in analog
at the wave pattern of the final iteration output, the value is output in analog according to the setting in 'CH1 Output setting
during wave output stop' (Un\G524).
• Unlimited repetition:
The digital value of the wave pattern end point is not output in analog.

A wave pattern that is
repeatedly output in analog
(1) In the limited repetition, after the value is output for the count set in the wave pattern output repetition setting, the analog value set in the output setting
during wave output stop is output.
(2) The value at the start point of the next repetitive wave always comes after the value at the end point of the previous wave. Preventing the output of the value
at the end point allows the wave to be connected seamlessly.
