Power OFF Interrupt Disabled

This parameter determines whether the power OFF interrupt task is enabled.
Parameter
Power Off Inter-
rupt disabled
Note This parameter is not supported when the CJ1W-PD022 Power Supply Unit is mounted.
Power OFF Interrupt Task
This parameter determines whether a power OFF interrupt task will be executed when a power inter-
ruption is detected. (When this parameter is set to ON, the regular program will just stop when a
power interruption is detected.)
The power OFF interrupt task will be stopped when the power hold time (processing time after
power interrupt + power OFF detection delay time) has elapsed. The maximum power hold time is
10 ms.
When a power OFF detection delay time has to be set, be sure that the power OFF interrupt task
can be executed in the available time (10 ms minus the power OFF detection delay time).
Note This parameter is not supported when the CJ1W-PD022 Power Supply Unit is mounted. (Refer to A-5 Oper-
ation for Power Interruptions.)
