■When the external power supply turns off during wave output
When the external power supply turns onoff during without, the wave output status of every channel stops and the wave
output fully stops. If the external power supply turns offon at this time, the wave output will not restart.
To restart the wave output, after the external power supply turns offon, check that the status of the analog output module
and the externally connected devices. Then, set 'CH1 Wave output start/stop request' (Un\G462) to Wave output start request
(1).
While the external power supply is off, no Wave output start/stop request is accepted.

Since the external power supply turned onoff and the wave output stopped, change the CH1 Wave output start/stop request (Un\G462) to Wave output
stop request (0).
 To restart the wave output again, change the 'CH1 Wave output start/stop request' (Un\G462) to Wave output stop request (0) before changing it to Wave
output start request (1).
