When the external power supply is turned off during the wave output
When the external power supply is turned off during the wave output, the wave output status of all the channels becomes the
wave output stop (the wave output stops). The wave output does not resume even when the external power supply is turned
on.
To resume the wave output, check the D/A converter module and external devices after turning on the external power supply,
and set Wave output start request (1) to 'CH1 Wave output start/stop request' (Un\G462).
Wave output start/stop request cannot be accepted when the external power supply is off.

(1): Because the external power supply was turned off and wave output stopped,
change the value set in CH1 Wave output start/stop request (Un\G462)
to Wave output stop request.
(2): To resume wave output, change the value set in CH1 Wave output start/stop
request (Un\G462) from Wave output stop request (0) to
Wave output start request (1).
