Mode transitions
The following figure and table describe the transition condition for each mode.
At the power-on or at the
reset of the CPU module

Wave output mode
No. Transition condition
(1) Set "Operation mode setting" to "Normal mode (D/A conversion process)" in "Basic settig" of the engineering tool and set "Output mode
setting" to "Normal output mode".
(2) Set "Operation mode setting" to "Offset/gain setting mode" in "Basic settig" of the engineering tool.
(3) Perform the mode transition by either of the following methods.
Method 1
Method 2
(4) Perform the mode transition by either of the following methods.
Method 1
Method 2
(5) Set "Operation mode setting" to "Normal mode (D/A conversion process)" in "Basic settig" of the engineering tool and set "Output mode
setting" to "Wave output mode".
*1 The wave output mode is independent of the other modes. After the module is powered on in the wave output mode, the transition to the
other modes is disabled.
After the module is powered on in any mode other than the wave output mode, the transition to the wave output mode is also disabled.
Checking method
The currently selected mode can be checked with the following items.

Execute the G(P).OFFGAN instruction (Argument "S": 0: Transition to the normal output mode).
Set the following values for 'Mode switching setting' (Un\G296, Un\G297) and turn on and off 'Operating condition setting
request' (Y9).
• Un\G296: 5260H
• Un\G297: 4441H
Execute the G(P).OFFGAN instruction (Argument "S": 1: Transition to the offset/gain setting mode).
