Power save on |
The system enters the power conservation mode since the
condition in which the program has not been executed continues
for the period longer than the preset period in the automatic
mode operation with the single block function OFF.
Setting is made at MC USER PARAMETER POWER SAVE "2. Power
save timer" in units of minutes; initial setting is 30.
