Operation of the wave output step action function
The wave output step action function is executed as follows.
Step action wave output
request (Un\G188)
CH1 Wave output status monitor
(Un\G401)
CH1 Wave output step action
movement (Un\G482)
CH1 Wave output current address
monitor (Un\G442, 443)
Analog output value
Change the value in 'Step action wave output request' (Un\G188) from OFF (0) to ON (1) to set the wave output status to the
wave output step action. By setting a value in 'CH1 Wave output step action movement amount' (Un\G482) during the wave
output step action, the address moves to the address of the target wave data for the output test. Set the amount for movement
from the current wave data address in 'CH1 Wave output step action movement amount' (Un\G482).
After the movement, the value in 'CH1 Wave output step action movement amount' (Un\G482) is changed to No movement
(0) and the wave data of the target address is output in analog.
The available range for movement by using 'CH1 Wave output step action movement amount' (Un\G482) depends on the
setting values of the wave pattern start address and wave pattern data points. The following shows the available range for
movement.

start address
If a value out of the setting range of the wave pattern data points is set to 'CH1 Wave output step action movement amount'
(Un\G482), the data is processed with the value within the setting range.
Execution of the wave output step action function
To use the wave output step action function, the initial setting for the wave output function must be set in advance. For details
on the initial setting for the wave output function, refer to the following.

■Switch to the wave output step action status
Switch the wave output status to the wave output step action in the following procedure.
1.
Change the value in 'Step action wave output request' (Un\G188) from OFF (0) to ON (1).
2.
Check that During wave output step action (3) has been set to CH Wave output status monitor in all the channels
where the D/A conversion is enabled.
To execute the wave output step action, check 'Latest error code' (Un\G0) and the ERR LED to check that no error has
occurred, and set 'Step action wave output request' (Un\G188) from OFF(0) to ON(1). When the value in the parameter
setting of the wave output is not set within the setting range in all the channels where the D/A conversion is enabled, the wave
output step action cannot be executed in all the channels.
