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.
Select 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 'Step action wave output request' (Un\G188) to ON (1).
No
Has the step action wave output request
Turn on CH Output enable/disable flag.
Check that the wave data value of the wave pattern start a
ddress is properly output in analog.

Example of testing analog output in CH1.
Set "Operation mode setting" of the module parameter so that the module is in
wave output mode.
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 becomes
the offset value because 'CH1 Output enable/disable flag' (Y1) is off.
When a value set in 'Step action wave output request' (Un\G188) has been
accepted, 'CH1 Wave output status monitor' (Un\G401) changes to During
wave output step action (3).
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 a proper one using a measuring
instrument such as a tester.
