The following table lists the setting contents for the wave pattern.

If the address value (total of the set values for "Wave pattern start address setting" and "Wave pattern data points setting" - 1)
exceeds the last buffer memory address (Un\G89999) of the wave data registry area, an error occurs. The error code
(1D9H) is stored in 'Latest error code' (Un\G0), 'Error flag' (XF) turns on, and the ERR LED turns on.

Description
Set the start address of the wave pattern to be output for each channel. The D/A conversion starts from the digital
input value of the buffer memory address set in this area and the converted values are output sequentially.
This area is for setting the points of the wave pattern to be output for each channel. From the start address of the
wave pattern, the D/A conversion starts for the points of wave data set in this area and the converted values are
output.
