Analog output test when the wave output function is used
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.
Start
Select the wave output mode in the parameter
setting.
Enable D/A conversion.
Turn on and off Operating condition setting
request (Y9).
Change the wave data value of the wave pattern
start address.
Set ON (1) to Step action wave output request
(Un\G188).
No
Has the step action wave output request
been accepted?
Yes
Turn on CH Output enable/disable flag.
Check that the wave data value of the wave pattern
start address is output in a proper analog value.

Example of testing analog output in CH1
Select "Wave Output Function" for "Output mode setting"
in the parameter setting.
Set CH1 D/A conversion enable/disable setting (Un\G500) to
D/A conversion enable (0).
Turn on and off Operating condition setting request (Y9).
Even though the D/A conversion is enabled, the analog output value
is the offset value because CH1 Output enable/disable flag (Y1) is off.
The value set in CH1 Wave output status monitor (Un\G401) is
changed to Wave output step action (3) when the value in
Step action wave output request (Un\G188) has been accepted.
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.
