208 0 to 15 0001 to 7D00: 1 to
32,000 ms
(1-ms units)
Default: 0000
(No minimum)
Set to 0001 to 7D00 to specify a minimum
cycle time. If the cycle time is less than this
setting, it will be extended until this time
passes. Leave this setting at 0000 for a vari-
able cycle time. (Can’t be changed during
operation.)
This cycle time will apply to the program
execution cycle when a parallel processing
mode is used.

225 0 to 7 00 to 0A:
0 to 10 ms
(1-ms units)
Default: 00
This setting determines how much of a
delay there will be from the detection of a
power interruption (approximately 10 to
25 ms for AC power and 2 to 5 ms for DC
power after the power supply voltage drops
below 85% of the rated value) to the confir-
mation of a power interruption. The default
setting is 0 ms.
When the power OFF interrupt task is
enabled, it will be executed when the power
interruption is confirmed. If the power OFF
interrupt task is disabled, the CPU will be
reset and operation will be stopped.
--- At startup or
at start of
operation.
(Can’t be
changed dur-
ing opera-
tion.)
