Normal mode
The normal mode is divided into the normal output and wave output modes. "Normal mode" in this manual refers to both the
normal output and wave output modes.
■Normal output mode
Used to perform normal D/A conversion. This mode D/A-converts the value set in 'CH1 Digital value' (Un\G460) and outputs it
as an analog output value.
■Wave output mode
Used for wave output. This mode D/A-converts the value set in 'Wave data registration area' (Un\G10000 to Un\G89999) and
outputs it as an analog output value.
For details on the wave output function, refer to the following.

For details on the offset/gain settings, refer to the following.

Wave output mode
No. Conditions for change
(1) In "Basic setting" of GX Works 3, "Operation mode setting" is set to "Normal mode", and "Output mode setting" is set to "Normal output mode".
(2) In "Basic setting" of GX Works 3, "Operation mode setting" is set to the "Offset/gain setting mode".
(3) The following values are set in 'Mode switching setting' (Un\G296, Un\G297), and 'Operation condition setting request' (Un\G70, b9) is turned
offonoff.
• Un\G296: 4658H
• Un\G297: 4441H
(4) The following values are set in 'Mode switching setting' (Un\G296, Un\G297), and 'Operation condition setting request' (Un\G70, b9) is turned
offonoff.
• Un\G296: 4441H
• Un\G297: 4658H
(5) In "Basic setting" of GX Works 3, "Operation mode setting" is set to "Normal mode", and "Output mode setting" is set to "Wave output mode".
*1 The wave output mode is independent of the others. After the system starts up in the wave output mode, it cannot change to another.
After the system starts up in a mode other than wave output, it cannot change to the wave output mode.
Checking
The current mode can be examined by the following.
