■When the disconnection occurs during wave output
When the disconnection is detected during wave output, the wave output status of the channel in which the disconnection was
detected becomes the wave output stopping, and the wave output completely stops. Even if the disconnection cause is
eliminated from the disconnection status, the wave output is not restarted.
By turning 'Error clear request' (Un\G70, b15) offonoff, the output of the value set in 'Output setting during wave output
stop' (Un\G524) is restarted.
To restart the wave output, 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 disconnection detection signal is on, no Wave output start/stop request is accepted.

Since the disconnection detection signal turned offon 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).
