[Wave output step execution]
After making change to the wave output step execution state, perform the wave output step execution using the following
procedure. By repeating this procedure, the analog output test and debugging can be performed when the wave output
function is performed.
1.
Change the wave data of the target subjected to wave output step execution to an arbitrary value.
2.
Set the value in 'CH1 Wave output step action movement amount' (Un\G482).
Set the following value depending on the direction in which to move control.
Shift direction
No shift
Forward movement
Reverse movement
3.
Check that the value of 'CH1 Wave output step action movement amount' (Un\G482) has changed to No movement (0).
4.
Check that 'CH1 Wave output current address monitor' (Un\G436, 437) has changed to the buffer memory addresses at
which to output the wave data.
5.
Check that the analog output value is proper.
[Terminating the wave output step execution]
Terminate the wave output step execution using the following procedure.
1.
Turn 'Step action wave output request' (Un\G188) ON (1)  OFF (0).
2.
Check that the CH Wave output status monitor for all channels have changed to Wave output stopped (0). In addition,
if the CH Wave output start/stop request was other than the wave output stop request (0), check that the status has
been forcedly changed to Wave output stop request (0) at this timing.
To perform the wave output after the wave output step execution terminates, set CH Wave output start/stop request in Wave
output start request (1).
• When the value is set for the CH Wave output step execution movement amount, the analog output may
suddenly change. It is recommended to use this function in combination with the CH Output enable/
disable flag to suppress the sudden change. For the combination, refer to the following.
Page 187 In the wave output mode
• By using this function in combination with the CH Output enable/disable flag during wave output step
execution, the analog output can be changed at a desired timing. For details, refer to the following.
Page 231 Analog output test when wave output function is used
• During wave output step execution, setting a value in CH Wave output start/stop request does not change
the wave output status. The wave output status can be changed by setting 'Step action wave output request'
(Un\G188) to OFF (0) so that the status changes to Wave output stopped.

2.4 Functions
Description
Control does not move to another buffer memory address of the output wave data.
Control moves to another output buffer memory address in the increasing direction from the
address at which the wave data is currently being output.
• If 10000 is set in 'CH1 Wave output step action movement amount' (Un\G482) when the
currently output wave data is at buffer memory address Un\G20000, control will move to
Un\G30000 as the output buffer memory address.
Control moves to another output buffer memory address in the decreasing direction from the
address at which the wave data is currently being output.
• If -10000 is set in 'CH1 Wave output step action movement amount' (Un\G482) when the
currently output wave data is at buffer memory address Un\G40000, control will move to
Un\G30000 as the output buffer memory address.
