(3) Analog output test in the wave output mode
The following shows the procedure of the analog output test using the wave output step action function.
The example of testing analog output in CH1 is described as well.
Switch the output mode to the wave output mode
in the switch setting.
Enable D/A conversion.
Turn on then off Operating condition setting
request (Y9).
Change the wave data value of the wave pattern
start address.
Set Step action wave output request (Un\G1072)
to ON (1).
No
Has the step action wave output request
been accepted?
Yes
Turn on CH Output enable/disable flag (Y1 to Y8).
Check if the wave data value of the wave pattern
start address is output in a proper analog value.

Example of testing analog output in CH1
Set "Output mode setting" to "Wave output mode" in the
switch setting.
Set D/A conversion enable/disable setting (Un\G0) to 000E
(for the L60DA4) or 00FE (for the L60DAVL8 or L60DAIL8).
H
(Set D/A conversion enable (0) only for CH1.)
Turn on then off Operating condition setting request (Y9).
Even though the D/A conversion is enabled, the analog output value
is the offset value since CH1 Output enable/disable flag (Y1) is off.
The value set in CH1 Wave output status monitor (Un\G1100) is
changed to Wave output step action (3) when the value in Step action
wave output request (Un\G1072) has been accepted.
Turn on CH1 Output enable/disable flag (Y1).
The analog output value changes from the offset value to the wave
data value of the wave pattern start address.
Check that the analog output value is proper using a measuring
instrument such as a tester.
