• Normal mode to offset/gain setting mode (the offset/gain setting mode status
flag (XA) turns ON)
• Offset/gain setting mode to normal mode (the offset/gain setting mode status
flag (XA) turns OFF)
POINT
(1) When the offset/gain setting mode is switched to the normal mode, Module
Ready (X0) turns from OFF to ON.
Note that initial setting processing will be executed if there is a sequence
program that makes initial setting when Module Ready (X0) turns ON.
(2) D/A conversion is discontinued if the mode is switched (from the normal mode
to the offset/gain setting mode or from the offset/gain setting mode to the
normal mode).
To resume D/A conversion, switch to the normal mode and then turn ON
Operating condition setting request (Y9).
