■ When Power Failure Occurred during Operation
● Momentary power failures of less than 20ms (or less than 1ms when “/V24” is specified) have no
effect on the controller operation (i.e., normal operation continues).
● For power failures longer than 20ms (or longer than 1ms when “/V24” is specified), however the
status will be as follows.
(The controller action at power recovery is the same as at power-on.)
• Alarm action: Continues (but alarms with a waiting action enter the waiting state once)
• Setting parameters: Maintained
• Auto-tuning: Canceled
