from the point at which power failure occurred.
(2) If power failure occurs during Program standby mode, the control resumes
from the Program standby mode.

[Wait function]
During the program control run, the program does not proceed to the next step
until the deviation between PV and Step SV enters the Step SV Wait value
when the step ends.
While the Wait function is working, the numeric value on the Step display flashes.
The Wait function is cancelled on the condition that:
(Step SV – Wait value) PV ( Step SV + Wait value)
When the program pattern is rising [The Wait function is cancelled at
(Step SV – Wait value) PV]
: Program pattern
: PV
: Program pattern which is delayed by T due to the Wait function
T : Wait time
